The Delight of Bristol Blue

 

QUESTION: I recently purchased a piece of what was described as “Bristol Blue” glass through an online antiques auction. I collect antique glass but this vase struck me as something unique. Although it looked like Victorian enameled glass, it resembled porcelain and the description said it was made in England in the late 18th century. I would really like to know more about this piece. I didn’t think glassmakers produced enameled glass that early Was it produced in Bristol, England, and thus the name, and who made it? And just how far back does Bristol Blue glass go?

ANSWER: Those are all very good questions. Let’s begin with the name. Even though this type of glass has Bristol in its name, glassmakers throughout most of England produced it. The blue in the name refers to the coloring used in the glass.

In the first half of the 18th century, near Redcliffel Backs, Temple Meads, Bedminster and other suburbs of Bristol, England, the squat chimneys of glasshouses and potteries silhouetted the landscape like giant beehives. But it was the age of porcelain, and anyone who could afford to buy it did so. Porcelain factories enjoyed the protection of kings, and European elite emptied their purses for priceless porcelain treasures. The arrival of an affordable substitute in decorated rnilch glass from Germany delighted Bristol glassmakers. For the first time, they had a perfect porcelain substitute  within their reach. 

The Venetians first made glass as an imitation of porcelain prior to 1500. Experts believe they used tin oxide as the agent to produce the white opacity in their glass. Eighteenth-century English white glass, called enamel glass in advertisements of the 1760s, was an intensely white, brittle material, generally a potash-lead mix, rendered opaque by the addition of lead arsenate. The porcelain-like, opaque glass  produced by the glassmakers of Bristol, was soft and smooth to the touch yet retained the fine heaviness of English crystal. It was an instant success, forcing the Bristol glassmen to borrow decorators from neigh-boring potteries to keep up with the public's demand.

England's glass excise tax of 1746 raised the duty on clear glass but didn’t tax opaque and colored glass because there was so little of it being made. This offered an excellent economic incentive for its increased production.

Chemists long knew that a powdered coloring could be premixed and supplied to glassmakers for addition to clear glass of their own making. But it was 18th-century German chemists from Saxony, who refined impure oxide of cobalt to produce a blue powder of unparalleled purity and uniform consistency. They exported their product, called “smalt,” to England, where a British merchant distributed it under the name "Bristol Blue."

The Bristol glassmakers quickly added the new deep-blue color to their already successful line of opaque white glass. Vigor & Stevens, of Thomas Street and Lazarus Jacobs, and later his son Isaac, of Temple Street, produced pieces primarily in deep Bristol Blue.

By the end of the 18th century the manufacture of blue glass became fairly common throughout England and continued to be marketed under the name of Bristol Blue. This makes it difficult, if not impossible, to identify glass made in Bristol from a piece manufactured elsewhere. The original term “Bristol Blue" referred simply to the coloring agent sold to glassmakers rather than to their finished products.

The early shapes, manufactured around 1770, emulated Chinese and English porcelain—pear-shaped covered vases, trumpet-mouthed beakers, and cruets—all   produced in sets. Glassmakers also produced scent or smelling bottles and snuff boxes, often facet-cut, with enameling and gilding, in both white and blue glass.

Early Chinese porcelain painters greatly influenced the 18th-century Bristol designs. The Chinese artists working at the Imperial Porcelain Factory excelled in delicate miniature enameled decoration on their opaque white glass. They often employed motifs of figures, birds, and European flowers much admired by the Emperor Chi’en Lung, who ruled from 1736 to 1795. Since most English glasshouses made their opaque white glass in competition with porcelain, most used the same styles and even the same artists to decorate both.

Glass decorator Michael Edkins linked the white and blue glass under the mutual name of "Bristol." At first, he apprenticed to an enameling firm in Birmingham, England, but at the age of 20, he took up residence in Bristol and settled down to decorate pottery dishes and tiles. At that time, artists painted the pieces with pencils made of bristles from the noses and eyelids of oxen. Graduating to glass, Edkins began decorating "enamel and blue glassware." He worked both independently and for Isaac Jacobs, Little & Longman, and Williams, Dunbar & Company from 1782 onwards. Instead of using enamel paints that needed to be fired, Edkins used standard oil colors, or plain gold gilt motifs, applied with unfired varnish, which he called "cold" decoration. 

Generally, artists decorated Bristol Blue ware with unfired or lightly fired gold varnish. Cruets and decanters often sported the name of their contents as well as intricate garlands and wreaths of plain gold.

Water, Water Everywhere

 

Fenn water bottle with ring

QUESTION: I discovered this unique water bottle at a local antiques co-op. While most antique water decanters are solid cut or pressed glass, this one comes apart into two pieces. A metal ring, with a rubber gasket to make the seal tight, screws onto the base. The mark on the bottom edge of the top section reads: “Perfection Bottle Co., Wilkes-Barre, PA Pat March 30-97.op part.”  What can you tell me about this type of water bottle?

ANSWER: You, indeed, have found a unique water bottle. Though a revolutionary idea, this type of water bottle appeared in stores for only a few years.

From the mid-19th century to the early 20th century, water bottles were standard items in many American Victorian households. They appeared on dinner tables either alone or with matching glasses and in bedrooms often with a glass that sat upside down over the top of the bottle. They also could be found on the nightstands in hotel rooms and steamship cabins, and on tables in railroad lounge cars. 

Cut glass crystal water bottle

At first, manufacturers made them of elegant cut glass, but that was too expensive for the average person. Some turned to using pressed glass in a variety of patterns which lowered their cost.

However, cleaning these crystal beauties posed a serious problem with hygiene. The bottle’s narrow neck made it hard to get a brush down into it, making it almost impossible to clean the inside surface of the bottle’s bulbous interior. But that changed in 1896 when William B. Fenn came up with the idea of a separating water bottle—one with pieces that could unscrew for easy cleaning.  On March 30 of the following year,  he applied for and received a patent for it.

Fenn’s separating water bottle had an ingenious design. He made the neck and base two separate pieces, with the bottom edge of the neck fitting inside the top rim of the base. A rubber gasket formed a waterproof seal between the two parts and a metal ring screwed over the joint to lock the pieces in place. 

Ceramic water bottle

Even though Fenn used glass for his original design, he stipulated in his patent that any material, including ceramics and porcelain, could be used for the bottle, itself, and any metal could be used for the joining ring as long it wouldn’t corrode.

It took nearly three years for Fenn's bottle to be available to the public. Priced at $4.50 each when they first came on the market in 1900, they were well beyond the means of the average person. Realizing he had to do something to increase sales, Fenn redesigned the pattern on the bottle so that it could be pressed instead of cut. Suddenly, the price per bottle dropped to 50 cents per bottle, or 34 cents each for a dozen, making the Fenn water bottle affordable for everyone.

Fenn’s invention was so successful that he decided to expand production. By October,1902, consumers could purchase a decanter

Fenn Royal water bottle

and stopper in four sizes—half pint, and one, two and three-pint versions. And during 1903; He expanded the line further to include other glass containers, such as   syrup pitchers and cruets, as well as bitters, cologne, and barber bottles, each with a different pattern.

The separating water bottle came in three models—the Royal, with a delicate design imitating cut crystal, the Imperial, also sold in two and three-pint capacities but without a pattern, the Optic, with a succession of single, convex protruding, vertical panels with rounded tops and bottoms, and the Colonial, featuring nine rounded panels with flat bottoms around the base. Each came in two and three-pint sizes, except the Colonial which also came in a half-gallon size.

In 1903, the Perfection Water Bottle Company and the Sterling Glass Company combined to create the Perfection Glass Company of Washington, Pennsylvania, with William Fenn as one of the initial investors. But the new company was only to last until 1907 when it closed its doors for lack of sales.

Fall is Cranberry Season

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.
