As Pyrex collectors, one of the questions we get asked the most is: “Do you actually use your Pyrex?” The question is yes, yes, and yes! We have vintage (and contemporary) Pyrex pieces are all over our house and we do use them every day. Some of the pieces we use the most are the #222 8″ x 8″ square and the #507 Heinz Promotional baking pans, as you can see here, we’ve used them to bake “His & Her” enchiladas (I sadly cannot have too much dairy, so mine has soy cheese on top). The vintage glass bakes up evenly and keeps the food piping hot, much more so than newer glass.
One important thing to remember is to NEVER put vintage glass through extreme temperature changes - we made the enchiladas in room temperature and popped them into the oven. Never take a glass pan from the refrigerator directly into a hot oven, that’s just asking for trouble. If you take good care of your vintage Pyrex, they will work faithfully in your kitchen and serve your family hot and delicious meals for a long time to come.
