I use these mostly for premeasured ingredients to make large recipes fluent in preparation. I purchased elsewhere but love these and my other pyrex. Came to this site which answered a question for me. That makes pyrex fantastic overall. I've only broken one pyrex in 25 years and I am not over cautious using glass in kitchen. I have different types of pie pans, but only pyrex has kept me using them year after year for baking. My holiday pies are perfect and consistent every year. Now I gift pies in pyrex. Doubles the gift.
