Horn a Plenty

 

QUESTION: I’ve always been fascinated by antique items made of horn. I see them in cases at antique shows all the time. I’ve even purchased a hair comb or two and a walking stick with a horn handle. But I have no idea how these items were produced. I assume most of them were made in the 19th century, but I’m only guessing. Can you give me some insight into the production of products from cow’s horn.

ANSWER: Horn has long been used to make various utilitarian objects. Ancient people blew through it to call meetings and such. Other horns held gun powder for muskets. And ornate hair combs made of horn were all the rage in Victorian times.

Long before synthetic materials like Celluloid, Bakelite,  and Lucite came on the scene,  Mother Nature provided an interesting assortment of moldable organic materials. These unique substances from plants and animals are known as "natural plastics."

Thermoplastics are materials that are made pliable by the application of heat, then molded with pressure or by casting in a cold mold. Additional applications of heat will subsequently re-soften thermoplastics and distort the original molded shape of an object. Though many modern thermoplastics are recyclable, antique thermoplastics can be permanently damaged by heat. Testing methods, such as exposure to hot water and the ever-popular hot pin test, can ruin valuable antique objects that are very often irreplaceable. So caution should be taken when trying to identify the materials from which some antique molded items are made.

Collectors seek objects fashioned from natural thermoplastic materials like cow horn in the 18th and 19th centuries. Over time, people used horn for a .variety of useful and ornamental applications. It required persistence and hard work to understand its unique properties. Through trial and error, ingenuity and luck, horn smiths developed successful fabricating techniques for working with horn.

Horn is a form of a protein called keratin, the same type of material as in fish scales, bird feathers, human hair and fingernails. Tiny compressed hair-like fibers, which can be seen with a magnifying glass, make up the structure of ' horn. Because of its unique protein formation, horn frays easily and has a tendency to split and crack during fabrication, making it difficult to work with. 

Horn smiths harvested, cleaned and fabricated horn into a variety of useful and ornamental objects such as dressing combs, hair ornaments, buttons, jewelry, decorative inlaid frames, trinket and snuffboxes. Because of Its beautiful pale translucent quality, they used horn extensively during the Edwardian Era for producing Art Nouveau accessories that depicted the dragon fly motif. 

Horn was a plentiful by-product of the meat and leather industries. It had been used for centuries n its raw state to make objects like powder horns and for fashioning common utilitarian items such as serving spoons and shoehorns. Oxen, steer and cow horn ranged in color from pale cream to light mottled gray. Buffalo horn, obtained from India, Thailand, and China, was dark brown. Domestic cattle horn vas plentiful and ranged in color tones from pale grayish green to streaked dark brown.

Manufacturers used raw cattle horn to make pressed rattans, umbrella and utensil handles, jewelry items and dressing combs. But Before these finished products could reach consumers, they had to first be fabricated. This process actually began with the meat industry.

Slaughterhouses had a surplus of raw cattle horn, which they stockpiled into various sizes and colors. This they sold cheaply to manufacturing companies or merchants who were in the business of applying horn to fabricators. A representative from the fabricating company would carefully select horn for specialty items like ornamental hair combs. Some representatives traveled the world searching for fine horn. When color wasn’t a consideration, the horn went for making common utilitarian objects like utensil handles or buttons.

After sorting, fabricators prepared the raw horn for the first step in processing. Workers trimmed the ends away by means of sawing two cross cuts—the first called the "head" or "rootº cut and the second the "screw" or "tip" cut. They then gathered the tips  to make utensil handles and buttons and used the ragged edges of the head cut to produce fertilizer.

They then sent the trimmed horn to the "opening department" where they soaked it with water and heated it over an open fire until it became softened. Another method commonly employed by fabricators involved softening the trimmed horn in huge vats of hot water or oil.

Nevertheless, once sufficiently pliable, the horn was ready to be split open. In order to prevent waste and in an attempt to end up with a rectangular piece of material, workers made an elongated, spiral cut beginning from the widest part of the horn up through the narrow section. After slitting, they forced the  horn open using tongs, and then placed it between screw plates to flattened it.

Fabricators often performed special finishing techniques on raw horn to change its appearance. They frequently clarified and sometimes stained it. The clarifying process involved squeezing the cleaned and flattened material between heated and oiled iron plates under tremendous pressure until it became translucent. Lantern makers used clarified horn, which had a slight greenish hue, as a "glaze" instead of glass in lanterns throughout the 18º and 19" centuries. Another use for ultra thin, translucent sheets of horn was to layer them between the pages of important documents in order to protect them from damage caused by bleeding inks. But the most important application of clarified horn was in the production of fancy ornamental hair combs.

Horn smiths stained clarified horn to resemble expensive tortoiseshell by first exposing it to diluted nitric acid which turned it a pale yellow. Once they achieved the desired amber color, they sprinkled and streaked the horn with a mixture of caustic soda, litharge, or lead monoxide, and dragon's blood, a colored resin derived from the rattan palm. This solution reacted with the nitric acid in the treated horn and turned the affected areas orange. The end result was a mottled imitation of tortoiseshell in mellow shades of amber and orange. Records show that in the late 1880s the comb factory of Stewart & Company of  Aberdeen, Scotland, used 3.5 million horns to only 600 pounds of authentic tortoiseshell per year.

Warming Up on a Cold Day

 


RS Prussia chocolate pot
QUESTION: I recently purchased what looks like a porcelain coffee pot. However, it has a decorative spout that has what seems like a bridge across its top. The floral design is delicately painted and on the bottom is stamped the name R.S. Prussia. Can you tell me anything about this piece?

ANSWER: What looks like a coffee pot is actually a chocolate pot, used by Victorians to serve hot chocolate on cold winter days. 

By the mid-17th century, chocolate was well established and sought after by the well-to-do in Italy, France, Germany, and finally England. From the time Spanish explorers brought chocolate back to Europe, people served chocolate hot. But the chocolate tasted bitter, so it became necessary to add sugar, vanilla, and jasmine to it to make it more palatable. Since chocolate was expensive, only the wealthy could afford this exotic drink.

Chocolate from bean to processed
Mechanization during the Industrial Revolution made processing of cacao beans more efficient and brought down labor costs. A Dutch chemist, Coenraad Van Houten patented a process that defatted and alkalinized the chocolate in 1828, making possible the mass production of cheap chocolate in powdered and solid forms.  

As chocolate's popularity spread throughout the Continent, people needed vessels to serve it. Chocolate pots began to appear in a variety of forms and materials, including earthenware, tin, pewter, tin-plated copper, porcelain, gold, and silver.

Potters created the first commercial chocolate pots of earthenware, but by the early 19th century, porcelain ones began to appear, coinciding with the decrease in the cost of chocolate and its availability to everyone, regardless of their economic status. At the same time the porcelain chocolate pot changed. Since the cocoa made from the cacao bean dissolved in hot water, whipping the chocolate was no longer necessary, so the hole for the molinet—the wooden stirrer—originally placed in the lid of the pot was no longer needed. By the mid- to late 19th century, most porcelain companies produced chocolate pots with solid lids.

Factories began producing a variety of affordable chocolate pots for the average household. Production peaked in the mid-to late 1800s, but continued until the mid- 1900s when people’s preference switched from hot chocolate to coffee.

Due to the widespread popularity of hot chocolate, chocolate pots are readily available to collectors, both online and at shows and auctions. For example, eBay has over 500 chocolate pots listed in active auctions. Prices vary widely and depend on material, with silver pots being more expensive than porcelain pots. Value also depends on the age and maker, as well as where the pot is being sold.

While the average porcelain chocolate pot sells for about $100, the higher quality ones from Meissen and R.S. Prussia range in price from $500 to $5,000. Chocolate sets—a pot with six tall cups and sometimes saucers—tend to sell for more than individual pots. Also, larger pots and those with floral or scenic designs are more expensive than smaller ones without decoration. Unmarked pots and those from lesser-known factories often sell for less than $100. 

Before starting a chocolate pot collection, examine a variety of chocolate pots being offered by reputable dealers. Read books on specific manufacturers such as Limoges; R.S.Prussia. and Nippon, and visit repronews.com, e-limoges.com and rsprussia.com online. Lastly, if you’re not sure of a chocolate pot's authenticity, don't buy it.

The Look of Beauty



QUESTION: I recently have become interested in possibly collecting ladies’ compacts. I see them at flea markets all the time and the prices are reasonable enough to fit my budget. Also, I live in an apartment, so their small size is a plus. But I don’t want to randomly begin collecting them without knowing a little about their background. What can you tell me about ladies’ compacts? Are they a good item to collect? Will I be able to find enough of them to make collecting them worthwhile?

ANSWER: They say good things come in small packages and ladies’ compacts are a good example. These little treasures not only represent a lost art but are also a connection to the past that’s still affordable.  With so many different types on the market, you’ll have no problem finding plenty in to fit your collecting budget.

For the sheltered few who may not know, compacts are devices women carry that help them pursue their quest for beauty. Many of the compacts are works of art themselves. They first appeared during in the early 1900s. In 1908, Sears, Roebuck & Co advertised a hinged, silver-plated case that sold for 19 cents, described as “small enough to carry in the pocketbook.” This small and round housing for face powder, puff, and mirror became known as a compact. By the 1920s, during the age of the flapper, the compact had become a fashion accessory. And right from the beginning there was lots of competition.

Manufacturers used metal because it was readily available, cheap to produce, and could be brushed, enameled, engraved, and painted. Sterling silver was extremely popular, as was brass, aluminum, gunmetal, nickel, and gilt bronze. Those made at the close of World War I featured shapes, patterns, and motifs that reflect the geometric style of what would become known as Art Deco.

The companies making compacts had intensive marketing campaigns, assuring women that they simply had to have a collection of compacts, not just for every occasion, but also to make a particular statement during each occasion. A Coty double compact advertisement urged women to "be lovely always”— morning, noon and night... and it is so exquisitely smart with its polished platinum tone that you will feel a subtle bit of pride in having it in your handbag.”

The ones most sought after by collectors, however, include those made by obscure companies such as Fisher, La Mode, F & B, R & G, FM Company, DFB Company and the makers of Italian silver vermeils.

Volupte, founded in 1920 in Elizabeth, New Jersey, made one of the most desirable designs —the Golden Gesture Hand, designed by Ruth Warner Mason for a special promotion of "Genuine Collector's Items." These compacts are also referred to as the "Praying Hands" or "Gay Nineties" compacts. The most desirable and costly ones feature either a black or white lace mitt and enhanced with a faux engagement ring, diamond bracelet, or with manicured fingernails or multiples of these enhancements. The hand compacts are about five inches long and can cost as much as $800 each.

These compacts are extremely fragile and dent easily. They’re relatively rare to find in anything but the plain gold version, which sells cheaply compared to the decorated ones. The latter are rare and even then, to get one in mint condition is like finding a needle in a haystack. Condition on these is very important with compacts, as with other collectibles. Dents and wear will lessen their value considerably. Beginners should always seek the unusual over the commonplace.

At one time, compacts were all similar in design. Collectors call these "flapjacks" because of their shape. They measure approximately 4½ to 5 inches and their size allowed a woman to see herself from her chin to the top of her hairdo. However, the cases of these large flapjacks often warp. If the mirror is intact and the case closes, collectors usually overlook any side gaps. The design and overall condition is the deciding factor when it comes to value.

Divine compacts, on the other hand, are small but often have fantastic designs. Many are souvenirs, depicting buildings, cities, landmarks, or world's fairs. Generally, prices for souvenir compacts are lower, but there are still some very stunning examples out there.

Guillouche compacts are highly collectible. The guillouche technique was an attempt to copy Faberge. By using colored foil stamped with appropriate patterns and topped with a clear plastic dome, the results were surprisingly effective. Not to be confused with cloisonné, guillouche enameling always has a translucent pattern. Faux guillouche is stamped on foil with a plastic top. Compact experts define genuine guillouche as machine-engraved decoration on metal, over which a translucent enamel is often applied.

Many companies marked their compacts on the powder cover or inside the powder well and on the puffs. Sterling compacts may have a word or number stamped into the tiny rims of the mirror or base. These marks are highly desirable by collectors. These can be identified by old catalog advertisements or simply by getting a feel for the quality of workmanship that particular company produced. However, even an unknown compact with no identifying features can still be a work of art and be of high value.

Before purchasing a vintage compact, the beginning collector judge the quality of construction, detail of artwork, and the type of base metal. Top quality items will always retain their value —an unmarked piece may have been produced by a small company that made excellent pieces and therefore there will be fewer of them, thus the price will be higher.

Collecting compacts should be fun. Part of the fun is in discovering unique pieces. It’s like finding a piece of history.
