I used it on a cookbook I was fixing up for my grandma. The slick surface made the knots pop open after just a few page turns. I redid the binding with cotton thread and it's solid as a rock now. Trust me, natural thread is worth the extra few cents!

PSA: I was wrong about quick cooling for small pieces
Glass thickness definitely plays a bigger role than some think. My cousin makes jewelry and she always measures her pieces before firing. She says even a millimeter extra can mean waiting hours longer. People probably don't realize how thin their glass should be for quick projects, right?
