First we went to paul Wissmach Glass.The company got its start in 1903.They make sheet glass used as stain glass and art glass. They made wire glass and glass numbers but no longer do They can make 5000 colors and tints.and 18 different patterns.Their biggest oversea custmers are in the mideast especially the United Arab Emirites.
It is 120 degrees on floor. It takes glass 40 minutes to get from one end to the other Every 26 seconds there is a new pour of glass.It goes 120 feet and when through it is still warm to touch. The glass is thin and32inches by 84 inches. Everything is cooled by water and water creates a steam barrier so glass does not stick.The process in video.
1. Carts called ladles are rolled to furnace and collects glass and brings to table. and pour.2 Glass is folded with paddles
3. molten glass push to roller. As it rolls out flat surface comes out so it has flat piece of glass on it.
4. Allowed to cool for very short time a long slim tool is used to make sure it is not sticking by running it between glass and surface then it is push on conveyer belt
5. At end of belt it is removed and cut

I still can't believe that we were able to get that close to the whole process. Seeing the glass panes made was fascinating.
