I’ve been using Bullseye Thin shelf paper for my projects. At present I am using a microwave kiln to experience glass fusing before moving up to my Skutt kiln. As long as the pieces I fuse have some weight, the fusing goes well. Some of the pieces I want to fuse are light in weight and found out the paper curls up, the layers separate and some of the pieces crack. Is there anyway to flatten the paper so it doesn’t curl up?Thank you.
