Glassmaker's chair

Glassmaker's chair

The glassmaker's chair is a device used in glass production . The chair is known from the wedding of Venetian glass production. It is used to manufacture hollow glass products such as bottles and similar products. The glassmaker sits at work and is supported by a helper by handing the raw glass mass for the product. The so-called backrests are used to roll the glassware.

So far, the so-called bancs de grands garçons , the maker’s chairs , have been used in bottle production. The inadequacy of this device was changed by the French inventors Collignon and Clavon in a glassworks in Trélon . They had a chair patented, which they called “banc à guides” (chair with guides) and which was intended to remedy previous manufacturing defects. When this device was used, all beads and rings in the bottle mouths fell away. The diameters were more even and any crooked necks could be straightened again.
