When did glass paperweights become popular?

Glass paperweights first gained popularity in the mid-19th century after being displayed at various expositions, most notably the Great Exhibition of 1851 at London’s Crystal Palace. Marvels of artistic skill and also affordable, they soon became the ultimate desk accessory, bringing flowers and other natural subjects that perished in the winter into the home. Collectors during this period included Sidonie-Gabrielle Colette, Oscar Wilde and Empress Eugenie of France. 

By the turn of the century, interest had waned, but in the 1950s artists like Paul Ysart and Charles Kaziun sought to rediscover the secrets to making glass weights. They also paved the way for hyper-realistic paperweight artists like Paul Stankard.

How are they made?

Incredibly, everything inside the weight is also glass: the flowers, the salamanders, the insects — everything. Most of the weights in the Neustadter Collection, which was offered at Christie’s in 2016, were made either using millefiori canes or lampwork. Millefiori or ‘thousand flowers’ canes are produced by layering molten glass into a pattern in a fat cylindrical shape, then pulling the cylinder to create an elongated pencil-thin rod. When the rod is sliced, the pattern can be seen in the cross section. Millefiori weights consist of many patterned canes, either packed closely together or in various other arrangements.

Lampwork weights are made by melting small coloured glass rods over a torch or flame and using tools to manipulate the softened glass. Examples of lampwork include butterfly and flower weights and snake weights.

How easy is it to identify makers?

Nineteenth-century paperweights were made in Venice, England, Bohemia and the United States — but the real epicentre was in France. The most famous and sought-after examples came from Baccarat, Saint Louis, Clichy and Pantin

Some weights have tiny canes included that help identify the maker and date. For example, the lot shown below has a small cane with the initial B and the date, 1848. 

Clichy has an easily identifiable rose cane that they use over and over in their millefiori compositions. Meanwhile, the Saint Louis factory is the usual suspect if you see a ‘dancing devil’ silhouette cane in its compositions. 

For a novice to begin learning to identify the further subtle distinctions between makers, examining a variety of pieces in books and in person is recommended. 

How important is condition?

When buying a weight, the condition and the size of the glass dome play a big factor for most collectors. Obviously perfect condition is preferable, but often a few scratches or marks can be forgiven if there is enough glass in the dome to polish them out. Large, unintentional air-bubbles or distracting bits of kiln debris often put collectors off. Lastly, to many collectors, a well-centred design is essential.

Does size matter?

Most weights range in size from around 2½ to 3¼ inches (6.3 to 8.2 cm), but then you have the exciting world of miniature and magnum weights. 

Miniature weights are defined as those measuring 2 inches (5 cm) or less. Magnum weights, like this massive Delmo Tarsitano salamander weight, measure at least 3½ inches (8.9 cm) wide. The size of the glass dome is also a factor — the bigger the dome, the greater the magnification of the design within.   

Are there many different types?

Other popular types of weights include: carpet-ground weights, which are composed of closely-set canes that are identical in type and colour; macedoine weights, a type of weight consisting of a scrambled, twisted mixture of canes or cane fragments and latticinio; colour-ground weights, which are made by using a transparent or opaque coloured glass as the background for a weight; and crown weights, which are hollow weights that usually alternate swirling white and coloured filigree canes radiating from a central millefiori cane.

How can I learn more?

The best way to learn more about paperweights is to look at them carefully, preferably in person. There are some fabulous collections to visit in the United States, including the collection of Arthur Rubloff at the Art Institute of Chicago; the Amory Houghton collection at the Corning Museum of Glass in New York; and the Bergstrom-Mahler Museum in Neenah, Wisconsin

Paul Dunlop’s The Dictionary of Glass Paperweights, An Illustrated Primer  is also quite helpful for an aspiring paperweight enthusiast.
