And then, I would cut this off, over that piece of thin glass, and by rolling it out with my rolling pin into a little pancake, the gold leaf itself is 3/8 of an inch square. Then these had to be annealed. Here I’m rolling it with my rolling pin to make it 3/8 of an inch thick...” (Gunther, Ariel. Transcript of Bryn Athyn glassmaking lecture.
