3-Vtg PYREX Baking Dishes Glass Pie Pan 208-209-210

These are the older pie dishes, all CAPITOL letters. Made with soda-lime, tempered, and borosilicate. Borosilicate glass includes boron trioxide, which has a low thermal expansion. This suggests unlike normal glass, it won't break when exposed to major temperature shifts such as taking a dish from a fridge to an oven. This is thanks to boron trioxide, the element that makes glass resistant to major temperature changes. * You Will receive one each * #208 * #209 * #210 These are in Very Nice Pre-Loved Condition & may have small imperfections
