Pressed glass

From Wikipedia, the free encyclopedia

Pressed glass is a form of glass made using a plunger to press molten glass into mold. It was first patented by American inventor John P. Bakewell in 1825 to make knobs for furniture.

The technique was developed in the United States from the 1820s and in Europe, particularly France, Bohemia, and Sweden from the 1830s. By the mid-19th century most inexpensive mass-produced glassware was pressed. One type of pressed glass is carnival glass.

The method is also used to make beads.
