Bubbles #1
3 ¾ in high x 4 ½ inches width x 4 ½ inches depth
The hot glass bubble on the blowpipe is inserted and blown into a specialized brass mold (called a pineapple mold), creating tiny indentations on the surface of the glass in a distinct pattern roughly representing the surface of a pineapple. Then air must be quickly sucked out of the bubble in order to release it from the “prongs” on the inside of the mold, and then quickly re-inflated before reheating it. I often choose to fill in these surface indentations with colored glass powders, but the indentations can be left as is. Carefully reinserting the piece into the furnace results in a clear layer of glass encasing either the colored “dots” or the indentations, hopefully resulting in capturing small air “bubbles” in the indentations on the surface of the bubble.
