Cold glass techniques in an industrial contextGlass pieces can be made "ready" in the hot shop, that is so there is no need for post-processing. Examples of hot-shop ready-mades abound here at Bergdalahyttan: all of the "Blue edge" products, several of the art pieces etc.
Examples of "cold" techniques are cutting, engraving, etching (nowadays mostly sandblasting) and painting.
We have on display a planer and a modern engraving machine. They sit in the museum, wainting for us to
clean them up, understand and describe them.
We hope we can get hold of a cutter's wheel, but in the meantime we can only refer to links to videros.
However, the industrial machine (as in "time-saving device for mass-producing patterned glass") we are most proud of is the pantograph, and as acid-etched glass is little known these days, we will start with exploring the history and technique of etching drinking vessels.
We have collected some of the history of glass etching on the page Acid etching.
There is also a page of a modern alternative to hand-painting: Decals for decotation
