The Glass Stash:
When I first started working with glass I think I went a little crazy. Spent every penny we could dig up for glass and supplies….Beans and rice for dinner again! It was a little bit of forethought for us since glass skyrocketed to prices that you could not imagine. I thought the price for a pound of Morretti was kind of high for glass, I just needed all those colors and at least a pound of each, and I didn’t want to take the chance of running out. In reality I could never use all that glass in a life time, but I’m still working on using it all up.
I added Bullseye Glass to my stash about ten years ago and just love the vibrant colors. It is a little stiffer than Moretti and sculpting with it is a dream. I am willing to pay the price for the Bullseye glass but just can’t stock pile it like I did when we started melting glass.
Norm built us a shelf system for the pvc pipe we use to store all of our glass. Bullseye, 90coe on one side and all the 104coe on the other side. I only have one coe on my work top at a time and as of yet haven’t mixed them up. “YET”!
COE stands for the Coefficient of Expansion in the glass. The expansion of the glass when it is hot and when it is cooling off will differ between different glass. So you really have to be aware of the coe of your glass before you start using more than one color for your beads. If you mix different coe’s your glass will cool at different rates and cause the glass to separate from the other. This will cause your beads to either crack or break entirely. There is a wealth of information on the coe’s of glass out there for the lampworker, and if you have any questions that I can answer I would be more than happy to do that.
