There are a number of different glass manufacturers out there in the wonderful world of glass. I talk about Bullseye quite a bit but there’s another glass maker in Portland, OR. Uroboros Glass makes glass for all types of glass fun. Casting, fusing, bead making and stained glass. They also make glass in different coefficient of expansions, the COE. They make 90, 96 and 104, which covers quite a range of needs of the glass enthusiasts out there. A video of their shop shows how they make their glass sheet and it is very fascinating. I love watching how glass is made…hopefully you will too.
