| Description: | To create the exact thickness needed for the glass tesserae, the molten glass was ladled onto a metal table or “marver” and rolled between two metal bars of the height needed. “…we cast this onto a piece of very smooth cast iron, and then I made this rolling pin out of a piece of three-inch pipe, and I roll it out into an uneven pancake, about 3/8 of an inch thick. This was then annealed, and then it had to be cut up into these small tesserae for the mosaic work” (Gunther, Ariel. Transcript of Bryn Athyn glassmaking lecture. Raymond and Mildred Pitcairn Archives, Bryn Athyn, Pennsylvania). Ariel Gunther (1903-1993) was in charge of operations at the Bryn Athyn glass factory. |
