  1. Borosilicate is a favorite glass for all sorts of hobbyists, not just for making Klein bottles. It's very strong and very easy to work, and you can form it into all sorts of shapes. But it's significantly more expensive than soda–lime glass, so you don't see it much in common household applications.
