Or do you mean a glass shop in sense of a store selling glassware?
This is strange. I replied to your post, but the reply isn't showing.
The glass shop makes large pieces of glass. Most of them are proprietary designs, so my boss doesn't talk about them in detail. I'm not exactly sure what all of them are. Some may be similar in size to the panels on the greenhouse that you showed. I think most are more specialized.
I've missed the first part of the moving effort because I was still sleeping after last night. I may join them later in New Orleans or just wait here to help unload when they get back.
