Pyrex glass cookware and bakeware in a wide variety of sizes and shapes–even a glass roasting pan. Silica (a compound found in quartz and sand) is the main ingredient in making the heat-resistant glass, then “eight ingredients are added and some broken glass”. So while it doesn’t contain recycled glass bottles, broken glass within the factory is recycled back into the pot. Pyrex is durable (so it can be reused for years without breaking or chipping) and it saves energy (Pyrex glass rather than reflecting oven heat waves, thereby reducing cooking time over earthenware, porcelain or enameled dishes).
