I make goblets out of a phosphate opal and usually use the color right out of the pot. Well one day I got an order for a few of the opal goblets that I didn't have in stock so I made them out of a bar I had from the last melt. When they came out of the oven and I set them next to the other goblets I could see the ones made out of bar were not nearly as bright and lively. They were more gray. So now I only use that glass out of the pot. All about the thermal history!
