The chalcedony glass

Chalcedony

The chalcedony glass is a particular decorative type of glass made from a mix of coloury metals, mainly green and purple; this is to imitate the precious stones such as the agate, The chalcedony, the onyx, the malachite, the lapis lazuli and the jasper.

This particular hand craft work was first invented in Venice during the XV century but it only became popular when it was later utilised in Germany under the name of Schmelzglas, or enamelled glass.

The first items created in Germany are credited to Ehrenfried Walther von Tschirnhaus who tried experiments using porcelain in Meissen. Some English models are dated back to the XVII century and they are sometimes called Jasper.

In the XVIII century other objects were produced in marbled glass imitating the hard stones, overlapping coloury glass layers that would then been engraved.

Around the middle of the ‘800, Lorenzo Radi rediscovered the secret of the Venetian chalcedony glass that was lost in the XVIII Century. The french name for this is “Jaspe”.
