As the winter nights are starting to get just a little bit brighter and Easter, spring and summer are just around the corner my thoughts turn to holidays spent in France and then obviously to the wealth of wonderful glassware that has come from that glorious country.

The French glasshouses of Baccarat, Clichy and St Louis were responsible for some of the finest and most inventive paperweights produced between 1845 and 1860. A limited number of English paperweights were made at about the same time at George Bacchus & Sons in Birmingham and examples of these in good condition can often realise high prices.

The main types of decoration are millefiori meaning “thousand flowers” and lampworking. Millefiori requires glass rods or canes arranged concentrically, formally or randomly before being cut and imbedded within clear glass. Those that include silhouette canes featuring animals and birds are always at a premium, as are dated examples.

Lampworking involves individually sculpted flowers, butterflies, fruit and reptiles, including snakes, made in coloured glass using a direct heat source before being captured in glass. Some of the most desirable weights are then overlaid with white and or coloured glass and facet cut to reveal the design inside.

The condition of a paperweight is important. Bruises and chips will make a paperweight undesirable to collect and therefore they will limit it’s value. Size is also important, in particular magnums at 10cm and miniatures, which are less than 5cms, are the most popular with collectors.

Sulphide Paperweights

A ‘Sulphide Paperweight’ refers to a paperweight which has a shaped “cameo” made from porcelain-like material encased within the clear glass. It involved cutting a hole in the hot glass sometimes through a bubble in blown glass, sliding in the insert which had been previously moulded, fired and left to cool and then resealing the glass or allowing the bubble to close by extracting the air through the blowpipe.

The technique of cameo incrustation or the encasement of porcelain medallions in glass was first developed in France in the early 19th century and it was used in America from 1814 and the United Kingdom from 1817. In 1819, English Glassmaker Apsley Pellatt (1791 – 1863) patented the technique, calling it “crystalo ceramie” in view of its French origins. The technique was not at first used in paperweights but was seen in glass plaques, pendants, vases and other decorative glass items before paperweight manufacturers realised the design appeal.

The three major paperweight manufacturers; Baccarat, Clichy and Saint Louis, all made sulphide paperweights. The value and appeal of these paperweights can depend on other factors besides the individual cameo, including the use of techniques such as detailed and elaborate faceting or engraving and the addition of millefiori (coloured glass rods shaped into patterns).

The objects cast inside the paperweights were most commonly people or animals sometimes both and the best with landscapes included. Many examples feature famous people or capture historical events with images sometimes cast off objects such as coins and medals. Generally, the more complex the design, the more desirable the paperweight as the process of moulding the objects was difficult and creating a single cast for one feature was the job of highly skilled craftsmen.
