Usually, they use iron shaping tools to form the glass into a cylinder but they had 2 sheets of red that they'd used the wood shapers on and they were incredible! Looking at this glass you can really see it's true nature. Glass is a super cooled silicious liquid. In other words, a liquid that has become solid without having a freezing point.
Blenko is a very strange company. If you want to buy their sheet glass you have to order from them or go to their factory, they don't go through a distributor. But if you go, set a limit to how much you're going to spend, cause you'll be like a kid in a candy store; "I want this and this and this..." and first thing you know, you're way over budget.
I'll talk more about the nature of glass later, but check out Blenko glass at www.blenkoglass.com
