Ruby---The Color of Christmas

 

QUESTION: My mother had a collection of ruby glass that she left to me. She would always display it around the Christmas holidays. To this day, I still take out select pieces to dress up my holiday table. What can you tell me out this beautiful glass?

ANSWER: Ruby glass is the dark red color of the precious gemstone ruby. This popular Victorian color never went out of style, and it’s still cherished today as it was then. 

Ruby glass has been around since Roman times. But the secret of making red glass, lost for many centuries, wasn’t rediscovered until the 17th Century in Brandenburg, Bohemia. Johann Kunckel, a chemist from a glass-making family, re-discovered how to make gold ruby glass around 1670.

To make gold ruby glass, include gold chloride, a colloidal gold solution produced by dissolving gold metal in Aqua Regia (nitric acid and hydrochloric acid) in the glass mixture. Tin (stannic chloride) is sometimes added in tiny amounts, making the process both difficult and expensive. The tin has to be present in the two chloride forms because the stannous chloride acts as a reducing agent to bring about the formation of the metallic gold. Depending on the composition of the base glass, the ruby color can develop during cooling, or the glass may have to be reheated to ‘strike’ the color.” Today, glassmakers use selenium to make ruby glass.

Over the years, the number of companies making ruby glass has diminished. Since the EPA has come down hard on these manufacturers, it became too costly to make ruby glass.

Other than its inherent color and possible shape, ruby glass pieces aren’t easily identified. Most Royal Ruby glass wasn’t marked or signed. The glass usually came from the factory with a sticker identifying the ruby color. During the 1940s, ruby glass manufacturers began using stickers which eventually got washed off or pulled off.

Major glass companies such as Sandwich, Cambridge, Mount Vernon, Gadroon, Blenko, Paden City, Hostmaster, Glades, Fenton, and Fostoria all made ruby glass in all the popular Depression glass patterns—Old Cafe, Coronation, Sandwich, Oyster and Pearl, Queen Mary, Manhattan.  

One company, Anchor Hocking, became synonymous with the manufacture of ruby glass. They initially began making and promoting it in 1938. Anchor Hocking's glass, which the company called Royal Ruby, unlike most handmade ruby, used a formula in which the principal colorant was copper. The result, an evenly colored, dark red glass. The amount of Royal Ruby in existence today is tremendous, far more than the amount of red glass from other manufacturers.

Anchor Hocking’s first made Royal Ruby in 1939 in round plates in dinner sets. Since this color became so popular, the company produced pieces of other patterns in this ruby color, including Oysters and Pearls, Old Cafe, Coronation, Bubble, Classic, Manhattan, Queen Mary, and Sandwich. However, difficulty in obtaining copper during World War II, halted production until 1949, after which Anchor Hocking began making an assortment of novelty items— apothecary jars, cigarette boxes, powder boxes, and such—sometimes combining it with crystal.

Footed and unfooted sugar and creamer sets, jam jars with crystal bottoms and ruby lids, plus assorted glasses--ribbed, old café, gold rimmed tumblers, and footed wine goblets—were among the myriad of pieces made in the late 1940s and early 1950s. Ice tea sets with large ice-lipped pitchers and six to eight tumblers were especially popular. 

Overall, ruby glass has appreciated in value because, like most glass items, breakage causes scarcity. But many items still sell in the affordable range of $15-65.

The King of Glass

QUESTION: I have a beautiful green glass cordial set that belonged to my great grandmother. It’s been passed down to me. I just love this set and would like to know more about it. I was told that it was made by the Moser Glass Company in Czechslovakia. What can you tell me about it?

ANSWER: It’s difficult to tell if your cordial set is in fact made by Moser. It’s definitely in its style but other company copied it. Moser was one of the only Bohemian glass companies to sign some of their works. Usually the signature is in gold enamel somewhere on the piece, but many pieces remained unsigned.

Of all the Bohemian glassmakers of the 19th century, Ludwig Moser, known as the “King of Glass,” is probably the most famous. The company was well known for its heavy and intricate gold enameling. But Moser wasn’t the only glass decorator to adorn blanks with this type of decoration. Glassmakers copied each other in an effort to get their share of the market. Like many Bohemian firms, Moser sold blanks to other companies for decoration and decorated blanks bought from other companies, such as  Loetz, Meyr's Neffe and Harrachov, so it can be difficult to tell if Moser indeed made a particular piece.
                   
Ludwig Moser was born in 1833 and began his apprenticeship in the glass business at age 14. From there, he became a skilled engraver. In 1870, he opened a refinery in Karlsbad, Bohemia, today Karlovy Gary in the Czech Republic, and employed other glass cutters and engravers who decorated glass blanks purchased from other companies. The firm's work earned Moser international recognition for his engraved drinking glasses.

By 1880, Moser was making the intricately enameled glass that’s most often associated with him. He designed them for the Oriental market, intending them to resemble the work of Arabian goldsmiths. In 1893, he took over a glassworks factory in Meierhofen bei Karlsbad, employing 400 workers, under the name of Karlsbaderglasindustrie Gesellschaft Ludwig Moser & Söhne and where his sons Gustav and Rudolf also worked. Here he produced shaded transparent engraved glass. Within a short time Moser’s company gained the reputation as the most prestigious producer of crystal in the Austrian-Hungarian Empire.

Because of the excellent quality of his work, Emperor Franz Joseph I appointed Moser as the exclusive supplier of glass to the royal family. He won numerous awards at the World Exhibitions in Paris in 1879, 1889 and 1900, and the World Exhibition in Chicago in 1893.

The firm also introduced pieces with applied glass flowers and fruits. These remained popular through the 1920s and marked Moser's departure from the intricately enameled luxury glass he had made earlier. By 1922, Moser Glass became the largest producer of luxurious drinking and decorative glass in Czechoslovakia. Moser's son, Leo, who had taken over the firm upon the death of his father in 1916, sold the firm in 1938. When the Communists took over Czechoslovakia, the government took over the Moser glass works but continued to use its name.

Moser glassware commands top prices, so collectors need to know their glassware or purchase pieces from reputable dealers to avoid paying top dollar for similar work by a less famous firm. Cups and saucers run about $300 a set, with larger pieces or those with unusual forms hovering around $2,000.

Prices for Moser engraved glass run about the same. Amethyst or green en-graved miniature rose bowls run around $275 to $350. Larger, more detailed pieces command more money. An amethyst intaglio engraved perfume and stopper runs about $650, a covered box about $800, and a tray about $500. Vases run $600 to $1,000 and up, depending on size and design. Green and crystal enameled pieces, which date anywhere from the late 19th to the early 20th centuries sell for under $200.

Nothing to Get Depressed About

QUESTION: My mother loves Depression Glass. She’s been collecting for over 20 years. I love the colors, but all the patterns confuse me. Other than being made during the Great Depression, why did so many companies make this type of glass and why is it so popular with collectors?

ANSWER: Of all the collectibles out there, Depression glass is one of the most popular with collectors, most likely for its rainbow of colors and its myriad of patterns. Depression glass is far from a depressing collectible. In fact, companies made it in such bright colors to raise the mood of people going through one of the worst times in their lives. They also made it affordable so that this little bit of joy could reach as many people as possible.

The common belief is that this clear, colored translucent, or opaque glassware got its name because it was made during the Great Depression. This is a bit of a misnomer because decorative glass of this type had been around since as early as 1914 and as late as 1960. However, the production of Depression glass did indeed reach its peak during the years of the Great Depression.

During the first half of the 20th century, the Ohio River Valley was the epicenter of glass production. Companies like Westmoreland and Fenton Glass had access to the raw materials and power they needed to keep their glass production costs down. Over 20 manufacturers made more than 100 patterns of Depression glass, some in entire dinner sets.

Although mass production of this low-quality molded glass made it fairly inexpensive at the time, not everyone could afford it. Everyday essentials were far more important, but thanks to glass companies like Indiana, Imperial, Federal, Jeanette, Hazel Atlas, and Anchor Hocking, the wares were available to everyone for a few pennies or nothing.

For instance, a bag of Quaker Oats flour might include a premium piece of dinnerware. The company also made laundry detergent, in which it packaged “a little extra something” to make the drudgery of  wash day more bearable. The pattern, size, and color were a mystery to the user until she opened the box. Collecting the pieces to use became a common pastime and made people’s lives a little brighter.  Other companies followed Quaker Oats’ lead and began using Depression glass as a premium to help sell their products.

Depression glass pieces also lined the shelves at five-and-ten-cent stores like Woolworth’s or if people went to the movies on Tuesday or Wednesday nights when patronage was low, they might win a set of dishes. Some theater owners handed out small pieces just for attending a show.

The Cherry Blossom pattern, made by the Jeanette Glass Company from 1930 to 1939, came in both pink and green. While most collectors of Depression glass favor the color green, it also came in a rainbow of other common colors, including crystal (clear), pink, pale blue, green, and amber. Less common colors included canary (yellow), ultramarine, jadeite (opaque pale green), delphite (opaque pale blue), cobalt blue, ruby (red), black, amethyst, and milk glass (opague white).

Later Depression Glass, made during the 1940s and 1950s, included American Prescut, sold only in clear crystal, and other patterns in ruby and forest green. The top-of-the-line pattern has always been Pink Miss America, made by the Hocking Glass Company from 1935 to 1938.

While over 100 companies made Depression Glass during the Great Depression, by the time it had ended, only half that many were still producing it. And of these, only seven—Federal, Hazel-Atlas, MacBeth-Evans, and U.S. Glass—produced this glass exclusively through the mid-1940s.

The Imperial Glass Company produced the first pattern, Fancy Colonial, in 1914, well before the Great Depresssion began. Westmoreland Glass has the distinction of making the English Hobnail pattern the longest.

The most colors made for any one pattern are 11, done for Moondrop and Rock Crystal, followed by English Hobnail by Westmoreland, Lincoln Inn by Fenton, and Floral by Jeanette, all with 10 colors each. 

Identifying Depression glass by mark can be difficult because few of the companies marked or labeled their wares. The only way to identify a maker is to know which company made the pattern. Using the numerous books and Web sites on Depression glass available today, it’s a fairly easy process. Some of the most common include Adam, American Sweetheart, Block Optic,Cherry Blossom, Dogwood, Floral, Georgian, Hobnail, Lake Como, Manhattan, Starlight, and Windsor. While some of the names reflect the style of the glass pattern itself, most do not. 

The best way to determine a genuine piece of Depression glass is to learn the pattern, dates of manufacture, colors the pattern, and any other known identifying marks. One example is the Cherry Blossom pattern by the Jeannette Glass Company, introduced in 1930 and made until 1939. The set consisted of 43 pieces different pieces, and the company made it in seven different colors—green, pink, crystal, yellow, ruby, jadeite, and dark green.

Depression glass was never made to be durable as it was only made to meet people’s immediate needs. Due to its popularity as a collectible and its breakability, Depression glass is becoming harder to find. Rare pieces often sell for several hundred dollars. Popular and expensive patterns and pieces have been reproduced, and reproductions are still being made, which has watered down the market for some patterns.

Shining Like a Jewel

Ice tea sets with large ice-lipped pitchers and six to eight tumblers were especially popular.

Overall, ruby glass has appreciated in value because, like most glass items, breakage causes scarcity. But many items still sell in the affordable range of $15-65.

‘Tis the Season for Cranberry

QUESTION: Every year at Thanksgiving, I bring out a set of eight sparkling pink glasses that used to be belong to my great-grandmother. They seem so festive and add a holiday note to our dining table. Can you tell me anything about these glasses?

ANSWER: Your glasses are made of cranberry glass, a very special type of glass favored by Victorian hostesses, especially around the holidays. Not only is this glass appropriate for the Thanksgiving and Christmas holidays, but it’s also a popular collectible. In fact, some pieces are worth too much to be used for fear of breakage.

Although glassblowers had been making colored glass since ancient Egypt, it was Johann Kunckel, a 17th-century German chemist from Potsdam, who came up with the red color by adding gold chloride to the clear crystal. During the 19th century, English and American glassblowers experimented with adding less gold choride, resulting in a pink glass which the Americans called “cranberry.”

And thanks to the virtuosity of these glassblowers there seems to be an endless variety of shapes and patterns of this glass on the market. In addition to tumblers and water pitchers, there are salt cellars, sugar shakers, cruets, jars, jugs, decanters, celery vases and finger bowls. Among the widely used patterns are "Swirl," "Coin Dot," and "Daisy & Fern." Some of the most rare and expensive items found from this time period are beautiful lamps and other lighting fixtures.
           
As with any collectible, cranberry glass can also be an investment. Pieces that sold for less than ten dollars a generation ago are now worth hundreds of dollars. Because of the natural fragility of glass, antique cranberry glass has become relatively scarce, though it does turn up in thrift and antique shops,  flea markets, and auctions.           

Although cranberry glass had peaked in popularity by the end of the 19th century, manufacturers produced it in quantity through the 1930s. The last two companies to make this unique glass—The Pilgrim Glass Corporation and Fenton Art Glass —went out of business early this century. Pilgrim Glass Company produced beautiful blown cranberry glass ranging from various vases and baskets to candle holders and sold them in department stores and gift shops around the country until 2001. At the time if the company's closing, cranberry was its most popular type of glass. Fenton Art Glass marketed new cranberry glass, featuring opalescent decoration with coin dots, daisy patterns and numerous other styles, through retailers around the country until it closed in 2011.

Cranberry glass has always been made in craft production rather than in large quantities, due to the high cost of the gold and the delicate mixing process required. Glassmakers dissolve the gold chloride in a solution of nitric acid and hydrochloric acid, known as “aqua regia.” Gold in the batch reacts with intense heat to create the beautiful cranberry color. A glassworker called a “caser” attaches a “bud” of this glass mixture to a blowpipe. Then the glassblower stands on a platform with the mold below his feet and blows the molten glass into the mold to create the desired shape. Afterwards, another glassworker places the piece in a “lehr” or annealing oven where it slowly cools to room temperature. Most cranberry pieces are hand blown or molded and often contain small bubbles and striations.
