Caught a bit of time this afternoon to try to get a better shot for the challenge. This is a close-up of an 18th century pressed glass water goblet. When things didn't go quite right, air got trapped in the blass when it was pressed into the mold that gave the goblet its shape. The result is what you see here. One large air bubble and many smaller ones. What appear to be cracks in the glass are really marls left by imperfections in the mold ore rubs and scratches left when the goblet was removed, still slightly soft. It was a hand made product so each goblet might have some unique marks, depending on the skill and care of the worker. My understanding is that the molds were made of hardwood such as rock maple, and after being used for a while, developed some imperfections. As long as they were not too severe, the mold would not be replaced.
