Rock Around the Jukebox


QUESTION: My husband recently purchased an old jukebox for a game room we created in our basement.  It’s a Wurlitzer 1015, and considering it’s 68 years old, it still plays pretty well. He paid $3,500 for it. Can you tell me more about this machine and others like it? Did my husband get taken on this deal?

ANSWER: While the jukebox is more or less a thing of the past, a few still exist in arcades and road houses off the beaten path and in the private collections of people who yearn for a return to those happy days. The one your husband purchased is the most popular of the oldies but goodies and normally sells for twice that amount.  

A jukebox, for those of you who may not know, is a partially automated music-playing device, usually a coin-operated machine, that plays selections from self-contained media, at first records, then CDs.. The classic jukebox has buttons with letters and numbers that restaurant, diner, and bar patrons pushed  in combination to choose and play a specific selection at first for a 10 cents, then later 25 cents, 50 cents, and upwards.

The earliest jukebox was called a  a "nickel-in-the-slot phonograph," and it came about in the late 1880s. The state-of-the-art invention, engineered by Louis Glass and William S. Arnold of San Francisco, was a coin-operated machine that was a modification of the phonograph, invented by Thomas Edison. Upon receiving a coin, unlocked the mechanism, allowing the listener to turn a crank which simultaneously wound the spring motor and placed the reproducer's stylus in the starting groove. Frequently exhibitors would equip many of these machines with listening tubes, similar to acoustic headphones, and array them in "phonograph parlors" allowing the patron to select between multiple records, each played on its own machine. Some machines even contained carousels and other mechanisms for playing multiple records. Most machines were capable of holding only one musical selection, the automation coming from the ability to play that one selection at will. The first of these music players was put at the Palais Royal Saloon in San Francisco on November 23, 1889. 

The jukebox continued to evolve. Hobart C. Niblack invented a way for the machine to automatically change records in 1918. This led the Automated Musical Instrument Company (AMI) to produce an innovative type of jukebox. Initially playing music recorded on wax cylinders, the shellac 78 rpm record dominated jukeboxes in the early part of the 20th century. 

In 1928, Justus P. Seeburg, who manufactured player pianos, combined an electrostatic loudspeaker with a coin-operated record player and gave the listener a choice of eight records. This Audiophone machine was wide and bulky and had eight separate turntables mounted on a rotating Ferris wheel-like device, allowing patrons to select from eight different records. Later versions of the jukebox included Seeburg's Selectophone, with 10 turntables mounted vertically on a spindle. By maneuvering the tone arm up and down, the customer could select from 10 different records.

Song-popularity counters told the owner of the machine the number of times each record had been played, which allowed the owner to replace less-played songs with more popular ones.

 

The term "jukebox" came into use in the United States around 1940, apparently derived from the familiar usage "juke joint", derived from the word "juke" meaning disorderly, rowdy, or wicked.

Jukeboxes had once been enclosed in wooden cabinets, but by 1937 manufacturers had begun to make them of gaudy plastic, frosted glass, jeweled mirrors, and chrome ornaments. Many of those Art Deco creations were self-contained light shows with polarized revolving disks, bubble tubes, and flashing pilasters. 

In the 1940s, the jukebox started evolving into the version we know today with colorful designs. Manufacturing stopped during World War II, however, as the materials were needed for the war effort. After the war, jukebox manufacturing continued, with the Seeburg Corporation introducing the vinyl record jukebox that used 45 rpm records. 

During those golden years, the Leonardo da Vinci of jukebox design was Wurlitzer's Paul Fuller, who was responsible for 13 full-size machines, five table models, and numerous speakers. The Golden Age of jukebox design ended when he suffered a heart attack in 1944 and died the next year. By then a new generation of larger jukeboxes had appeared, and the classic machines from the golden years—1937 to 1949—were, for the most part, relegated to the junk heap and forgotten. 

 became an important, and profitable, part of any jukebox installation. They enabled restaurant patrons to select tunes from their table or booth. One example is the Seeburg 3W1, introduced in 1949 as companion to the 100-selection Model M100A jukebox. Stereo sound became popular in the early 1960s, and wallboxes of the era came with built-in speakers, enabling patrons to sample this latest technology.

The popularity of jukeboxes extended from the 1940s through the mid-1960s, but they were particularly fashionable in the 1950s. By the middle of the 1940s, three-quarters of the records produced in America went into jukeboxes.

And even with all of today’s high-tech music devices, the sound from one of those old machines was fabulous. Nothing beats hearing an old 78 on a machine created just to play it. Those were the days.

Art Deco vs. Art Moderne

 

QUESTION: I’m a great lover of all things Art Deco, although I don’t know much about it. I’ve heard some people refer to this style as Streamlined Modern while other call it Art Moderne. Can you please tell me a little about this style? And what about Streamlined Modern? Is it related to Art Deco?

ANSWER: Art Deco and Art Moderne overlap, both stylistically and chronologically. Both were in vogue in the first half of the 20th century. But it's more a question of style than dates. While Art Deco emphasized verticality and stylized, geometric ornamentation, Art Moderne was a horizontal design, emphasizing movement and sleekness;.

The Art Deco style made its debut at the 1925 World's Fair in Paris—the Exposition Internationale des Arts Décoratifs et Industriels Modernes or the International Exhibition of Modern and Industrial Decorative Arts—but the term Art Deco wasn’t used until 1966. A group of French architects and interior designers, who banded together to form the Societe des Artistes Decorateurs, developed the style to incorporate elements of style from diverse modern artworks and current fashion trends. Influence from Cubism and Surrealism, Egyptian and African folk art can be seen in the lines and embellishments, and Asian influences contribute symbolism, grace and detail.

Art Deco was already an internationally mature style by 1925—one that had flourished in the years following World War I and peaked at the time of the fair. The enormous commercial success of Art Deco ensured that designers and manufacturers throughout Europe continued to promote this style until well into the 1930s. 

Sometimes Deco designers applied ornamentation to the surface of an object, like a decorative skin, but at other times the utilitarian designs of bowls, plates, vases, and furniture were themselves purely ornamental. These objects weren’t intended for practical use but rather created for their decorative value alone, exploiting the beauty of form or material. Among the most popular and recurring motifs were the human figure, animals, flowers, and plants. Abstract geometric decoration was also common. 

Victorians loved to apply ornamentation onto furniture, to embellish basic frames and shapes. With Art Deco, the texture and embellishment came from contrasts in a variety of colored woods and inlays or in the material itself. Designers often used burled or birds-eye or visibly grained woods, tortoise shell, ivory, tooled leathers. Lacquered glosses accentuated color differences. Animal skins and patterned fabrics in bright colors were also popular as upholstery.

Though it spread to other countries, Art Deco was a distinctively French response to the postwar demand for luxurious objects and fine craftsmanship. French designers utilized lavish materials and such rich, traditional decorative techniques as inlay and veneer on streamlined geometric forms.

Art Deco reflected the general optimism and carefree mood that swept Europe and the United States following World War I. Hope and prosperity are represented in sunburst designs, chevrons and references to the good life in the elegant figures depicted in casual, sensual poses, often dancing or sipping cocktails. The modern influences heralded a bright and shining future outlook that found its way to architecture, jewelry, automobile design and even extended to ordinary things such as refrigerators and trash cans.

Exoticism also played a role in Art Deco. During the 1920s and 1930s, the French government encouraged designers to take advantage of resources—like raw materials and a skilled workforce—that could be imported from the nation's colonies in Asia and Africa. The resulting growth of interest in the arts of colonial countries in Asia and Africa led French designers to explore new materials, such as ivory, sharkskin, and exotic woods, techniques such as lacquering and ceramic glazes, and forms that evoked faraway places and cultures. 

Art Moderne
 Moderne, also called Streamlined Modern, was an American invention that first appeared in the 1930s and lasted into the 1940s. Although taking its design concepts from Art Deco, it was a completely different style It was bigger and bolder. While Art Deco placed an emphasis on shape, Art Moderne was streamlined. Unfortunately, this is the style most Americans confuse with Art Deco.

Think of Art Moderne as Art Deco on steroids. Moderne was positively streamlined—at the time a new scientific theory that shaping objects along curving lines to cut wind resistance would make them move more efficiently. The furniture in this style was much more pared down, making its outline more geometric in sleek curves like a tear drop or torpedo. Moderne designers often conceived pieces as a series of escalating levels- similar to a staircase or the setback effect of skyscrapers that were rising in every city.

While rich colors, bold geometry, and decadent detail work characterized Art Deco, evoking glamour, luxury, and order with symmetrical designs in exuberant shapes, Art Moderne was essentially a machine-made style focused on mass production, functional efficiency, and a more abstract look coming from the Bauhaus in Germany.

Much of it was designed to be mass-produced, but even if it wasn't, it looked as if it could be: Art Deco's balance and proportion extended to regularity and repetition. Much of the decorative interest in a Moderne piece comes from the precision of line and duplication of functional features. Art Moderne designs often conveyed a sense of motion.

Art Moderne designers favored simpler, aerodynamic lines and forms in the modeling of ships, airplanes, and automobiles. In the modern machine age smooth surfaces, curved corners, and an emphasis on horizontal lines came into fashion. Streamlining appeared on everyday objects and buildings such as roadside diners, motor hotels, movie theaters, early strip malls and shopping centers, seaside marinas, and air and bus terminals. Trains, ocean liners, airplane fuselages, as well as luxury automobiles all sported the Moderne look.

People often refer to furnishings and buildings from the 1920s through the 1940s as Art Deco. Understanding the difference between Art Deco and Art Moderne isn't always easy, especially since Art Deco was originally called Moderne.

The Teapot King

 

Aladdin Teapot

QUESTION: My mother was an avid tea drinker. When she was a young woman, she began buying old teapots at flea markets and yard sales. When I grew up and left to go on my own, I started giving her a teapot for her birthday. Over time, she amassed a collection of some 50 teapots. She passed away recently, and her collection has passed on to me. I chose the teapots I bought for her because of their unusual shapes, but I noticed that a good many of them seem to be marked for the Hall China Company. I’d like to continue adding to this collection. Why would so many have been made by Hall China? And as collectibles, are these teapots of any value?

ANSWER: Indeed, the Hall China Company is the king of teapots. Lots of people probably have one and don’t know it.

Gold Decorated Los Angeles Teapot
Albany Teapot

Robert Hall founded the Hall China Company after the dissolution of East Liverpool Potteries of East Liverpool, Ohio, in 1903. Taggert Hall, Robert’s son, became president following his father’s unexpected death in 1904. The company initially made jugs, toilet sets, and utilitarian whiteware. Robert T. Hall’s major contribution to the firm’s growth was the development of an economical, single-fire process for lead-free glazed wares introduced in 1911.

Robert Hall died just a year after founding his company. One of his eight children, Robert Taggart Hall, took it over and immediately began developments to introduce the single-fire process, which had first been used centuries earlier by Chinese potters during the Ming Dynasty from 1368 to 1644. His aim was to change from the two-firing manufacturing method, using first a biscuit firing and then the glaze firing. With the help of staff chemists and ceramic engineers, Hall experimented from 1904 until 1911, when the process was successful. The new process fused together the white body, color and glaze when it was fired at a temperature of 2,400 degrees Fahrenheit.

Pear Teapot

The new glazes allowed the creation of brilliant colors never before seen on American china: 47 colors developed for the new process, which allowed for rapid expansion of the company and its product selections at the onset of World War I. After tepid sales of its new housewares lines in the 1910s, the company tried designing and selling decorated teapots. The teapot business was so successful that the company decided to expand it from the original three designs to a plethora of new shapes and colors. In the 1940s the teapot business began to dwindle. By the 1960s, probably due to the increased preference for coffee by the public, teapot sales had fallen to insignificance.

In the mid-1920s, Hall China began producing a range of ware exclusively for the Jewel Tea Company. Jewel started using Hall teapots as premiums, and then expanded the promotion to include its own line of distinctive dinnerware and kitchenware.

Globe Teapot

Hall’s teapots were durable, non-porous, and unlike other types of china, didn’t craze.  The Hall palette of colors included no fewer than 47 different variations over the years.  The non-crazing process used to manufacture its pieces were made to emulate beautiful wares made in China during the Ming Dynasty, although the shapes and decor didn’t generally show any Asian influence. 

Hall also produced novelty teapots shaped like cars, footballs, and doughnuts that remain popular with collectors although they're often difficult to find today. These include the popular Nautilus and Aladdin teapots.

Nautilus Teapot

A Selection of Hall Teapots
Hall produced over 160 different shapes and color combinations of teapots. The first, the Gold Decorated Teapot line, also known as the Los Angeles teapot, was extremely popular.

Loc Angeles Teapot

The second, the Boston teapot, which also began production in 1916, came in two styles, the Boston Knob, included here, and the Boston Sunken Lid. Both came in seven sizes from one cup to seven or eight cup. The Boston is one of Hall China Company’s earliest and most enduring styles. In 1916, the McCormack Tea Company purchased the Boston in the seven cup green. The seven cup green and brown Boston teapots were the first ones carried by the Jewel Tea Company in 1924.

Boston Teapots
Philadelphia Teapot

Another teapot Hall introduced in 1916 was the New York teapot and was one of Hall’s longest running styles, available from 1916 through 1989. It was originally and continually produced in nine different sizes for the Hall hotel ware line but was also added to the Gold Decorated line in 1920.  

The Philadelphia  teapot, produced during the 1920s, came in seven different sizes, ten, seven, six, five, four, three and one and a half cups. Later in that same decade, Hall introduced the Hollywood teapot which came in four, five, six and eight cup sizes.

Tea-for-Two Teapots

From 1930 to 1996, Hall produced the Tea-for-Two, a combination teapot and a hot water pot, It’s distinguished from the Twin-Tea set by the sloped shape of the body, It can also be found as a Tea for Four set. 

Musical Teapot

From the late 1930s to the 1940s, Hall produced one of two Globe shaped teapots. The No-Drip is a Globe shape teapot with a different spout and decoration. The Globe teapot, introduced in the late 1930s, was usually found with the gold decoration pictured. By 1942 it was available in black, blue, brown, cadet, canary, delphinium, Dresden, emerald, green, green luster, ivory, marine, maroon, orchid, rose, turquoise and yellow. 

Hall’s Musical teapot, made in the 1930s, wasn’t a success. The music box, which played “Tea for Two,” sat under the teapot in a “well,” held in place with a spring clip. Often, users would wash the teapot without removing the musical box, causing damage to the mechanism. 

In 1937, Hall added the Streamline to the Gold Decorated teapot line. It featured the standard gold decoration around the top, edge, and spout found on other teapots in the line.

Streamline Teapot

Doughnut Teapot

The Automobile was one of the Hall China Company’s Novelty teapots introduced in 1938. Although it has a very unusual shape it was very popular. Introduced in 1938, the Basket was another Novelty teapot that included the Doughnut, the Birdcage, the Football, and the Basketball. In 1982, Hall was commissioned to make a caricature teapot of newly elected President Ronald Reagan. After a partial delivery the customer defaulted on the remaining order and subsequently the teapots were sold at the local Hall Closet store.  

Automobile Teapot
Rhythm Teapot

Hall China produced some of its most beautifully designed teapots in the 1930s, many of which featured Art Deco styling. Introduced in 1938 in the 8-cup size with the 6-cup introduced the following year, the Airflow was colored marine in its standard design. It was perfectly balanced and was as simple to lift as a purse, easy to pour, plus the lid wouldn’t fall off.

Hall introduced the Rhythm teapot in 1939. Originally introduced as a gold decorated teapot with gold dots on the upper two drapes, it was later a part of the Hall American line and came in over 100 different colors. That same year, Hall produced a special souvenir teapot for the 1939 New York World's Fair.

1939 New York World's Fair Teapot
Twinspout Teapot

Designer Oscar Ottoson invented the Twinspout teapot for which he received a patent in 1938. Hall China produced it for the Twinspout Pottery Company of New York.  When a user removed the lid, there were two openings, the larger for the tea and the smaller for the hot water. 

Produced from 1939 to 1963, the Aladdin teapot was one of Hall’s most popular shapes. It came with either a round or an oval opening, both with and without infusers, and in narrow and wide bodies.

Sani-Gold Teapot

During the 1940s, Hall came out with the Sani-Gold teapot. It first appeared in the 1941 Hall China Special Catalog #4. The firm made it in three and six cup sizes, with grid in the spout  to catch the tea leaves which was also shortened for easy cleaning.. The style, often referred to as “pert” was also easier to store. 

Introduced in 1940, the Hook Cover teapot, produced only in the six cup size, had a lid that wouldn’t fall off when pouring. The body has a hook over which the lid fits, thus the name.

Hook Cover Teapot
Windshield Teapot

The Windshield teapot, introduced in 1941, had a collar similar to the one worn by Queen Elizabeth I of England.

From the mid 1950s through the 1960s, Hall produced the Parade teapot as one of its Gold Decorated teapots.. It had a hook cover lid and a non-slip handle.

Hall produced the E-Style Cameo Rose teapot, designed by J. Palin Thorley, another of Hall’s top designers, exclusively for the Jewel Tea Company from the 1950s to the 1970s. Another of its noted designers was Donald Schreckengost who designed the Pear teapot, first introduced in 1970.

E-Style Cameo Rose Teapot
Airflow Teapot

Hall China produced so many teapots during its existence that it’s nearly impossible for a collector to collect them all.

The Plastic That Shaped the Future

 

QUESTION: Recently I purchased a box of assorted costume jewelry at a flea market. What intrigued me was the variety of colorful plastic bracelets in the assortment. While these look like they’re made of regular plastic we know today, the dealer told me they were Bakelite. My grandfather once told me that Bakelite was the first plastic. He had an old radio that seemed to have a plastic case. At the time, I didn’t believe it because I thought plastic was a mid-20th century invention. What can you tell me about Bakelite? Who invented it and when?

ANSWER: Without knowing it, you’ve discovered a treasure of the early 20th century. Bakelite was a chemical miracle of the 20th century. It enabled manufacturers to make a variety of items—children’s toys, kitchenware, pipe stems, wall switches, appliance and cutlery handles, colorful radio cases, and yes, jewelry. Dubbed the “Material of a Thousand Uses” by the Bakelite Corporation, Bakelite was versatile and nonflammable.

Leo Baekeland developed this innovative form of plastic in his backyard laboratory in Yonkers, New York, between 1907 and 1909. He attempted to create a synthetic shellac when he discovered that phenol, or carbolic acid, and formaldehyde, when combined under certain conditions, resulted in a molasses-colored resin with unique and exceptional properties.

Once cured, the phenol formaldehyde resin could be ground into powder and mixed with a variety of fillers to create a molding compound that was practically indestructible. Slate dust, asbestos, wood flour and ground walnut shells were all used for this purpose, but because of their dark color, molded Bakelite was limited to shades of black, maroon and brown.

In1911, he founded the General Bakelite Company in Perth Amboy, New Jersey, which produced up to 200,000 tons of the plastic each year. Because it was resistant to heat, moisture, and chemicals, it became a component of the electrical industry. It also had excellent insulating properties, making it perfect for use in electrical insulators, switches, plugs and sockets. 

Making Bakelite was a multi-stage process. It began with the heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. This created a liquid condensation product, referred to as Bakelite A, which was soluble in alcohol, acetone, or additional phenol. Heated further, the product became partially soluble and could still be softened by heat. Sustained heating resulted in an "insoluble hard gum." 

However, the high temperatures required to create this tended to cause violent foaming of the mixture when performed at standard atmospheric pressure, which resulted in the cooled material being porous and breakable. Baekeland's innovative step was to put his "last condensation product" into an egg-shaped "Bakelizer." By heating it under pressure at around 300° F, he was able to suppress the foaming. The resulting substance was extremely hard and both infusible and insoluble. The range of colors available included black, brown, red, yellow, green, gray, blue, and blends of two or more of these. 

Bakelite came in various forms to suit varying needs, including clear material, for jewelry and smokers' articles, cement, used in sealing electric light bulbs in metal bases, varnishes, for impregnating electric coils, lacquers, for protecting the surface of hardware, and enamels, for giving resistive coating to industrial equipment. In addition, there was laminated Bakelite, used for silent gears and insulation; and molding material, used to form items of utility and beauty.

When Bakelite’s patent on phenol formaldehyde expired in 1927, other companies using the chemical came on the scene, including the American Catalin Corporation which pioneered a purified form of phenolic resin that did away with the dense fillers used in molded Bakelite. The company introduced casting resins in 20 different colors.

The Bakelite Corporation quickly developed its own phenolic resin, producing it in thousands of colors. In reality its recipes were exactly the same as American Catalin, except they experimented more with dye saturation and mixing colorants with clear resin to create mottled and swirled effects.

By the mid 1930s, several competitors had begun producing phenolics which forced the price of both Bakelite and Catalin down. One of these other companies, Fiberloid, introduced Opalon in lapis lazuli, mottled red, alabaster, onyx and mottled walnut, fabricated into board game pieces, jewelry, and umbrella and knife handles.

The introduction of electrical power gave rise to a wide range of labor-saving devices that utilized Bakelite and Catalin in one way or another. The modern appearance, durability and hygienic qualities of plastic made it superior to traditional substances.

Bakelite quickly replaced wood and metal in telephones, clock and barometer cases, as well as knobs and handles on small appliances like electric irons, toasters and cookware. Colorful Catalin cutlery handles and novelty napkin rings dressed up the table and brightened the kitchen.

In 1933 the Bakelite Corporation began to produce wood-tone radio cabinets of compression-molded phenolic resin. Thermosetting plastics resisted the heat generated by radio tubes, making Catalin ideal for radio cabinets. It wasn't long before colorful, modernistic Catalin radios began to make their appearance.

By 1936, various companies made two-thirds of all costume jewelry produced in the U.S. by fabricated molding and fabricating cast phenolic resin. The fabricating process, however, was labor-intensive and lengthy.

First, molds had to be made by dipping a steel master into molten lead. Once workers  assembled enough molds, others prepared phenolic resin and carefully poured it into each mold by hand. A technician carefully combined resins as casting occurred if special swirled or mottled colors were desired, the technician needed to carefully combine resins as they were being cast.

Once filled, workers wheeled the molds into a huge oven to be baked  at176 degrees F. until the resin cured. Curing time varied. Dark red and blue cured in three to four days while whites took six to eight days. Once the cast resin cured, workers removed it from the lead molds using air hammers. This always resulted in damaged molds. Other workers tossed the broken pieces back into the vat of molten lead to be melted down for reuse.

To make jewelry components, workers cut shaped or hollow phenolic rods into individual pieces, much like slicing a loaf of bread. Then they carved and machined by hand them for added adornment. Once they completed the decorative carving, they finished the pieces by tumbling or buffing on a polishing wheel.

Bakelite became a symbol of progress and modernity as the streamlined Art Moderne style overtook the chic style of Art Deco. The sharp-stepped sides of skyscrapers softened into curves, while boxy trains and automobiles became sleek, with fluid lines that created the illusion of speed and motion.

By the late 1930s, plastic moldings reflected the streamline design trends. Shiny surfaces, modernistic curves, waterfall fronts and facades, made to look like car grills, all found their way into jewelry, small home appliances and decorative household objects.

Perfectly suited to Bakelite and Catalin molds, the Art Moderne style enabled the resin to easily flow inside a curved mold. In addition, it was easier to mold, fabricate, and polish the resulting casts than the boxy, stepped sides and sharp corners of Art Deco designs.

Cast phenolic resins weren’t as durable as compression molded phenolic compounds because they shrank over time, often resulting in cracks. Catalin averaged a 4 percent shrinkage in the first 10 years. Cracks developed in radio cases because the parts were bolted to the housing, leading to stress as the plastic shrank.

Though companies produced Catalin in 20 opaque and translucent colors, engineers limited the color range because they felt all other dyes would cause instability in the plastic.

Unfortunately, Catalin reacted to ultraviolet light by converting to phenyl alcohol, which was brownish in color. That was why so many Catalin items are amber colored. The effect turned original white to butterscotch, bright blue into drab olive, green into butterscotch, and brilliant red marble into brown.
