Title:Assembling a mosaic for Glencairn
Source:Raymond and Mildred Pitcairn Archives, Bryn Athyn, PA
Medium:35mm slide
Description: Once a design had been completed, it was put onto a sheet of heavy paper and individual tesserae were glued to it. “Here you see one of the boys, actually. We gave them each a jar of this material [a special glue made of gelatin, glycerin and gum Arabic], and a little brush, and they would actually just put this paste on the paper and press the mosaic into it” (Gunther, Ariel. Transcript of Bryn Athyn glassmaking lecture. Raymond and Mildred Pitcairn Archives, Bryn Athyn, Pennsylvania).
