This is a very nice, great quality bakeware set that should be in every kitchen! It is heat resistant up to 500 degrees, lightweight, durable, beautiful glass that you will find so many uses for in the kitchen! We haven't had any of the glass chipping or cracking, and even having it only a few weeks they have definitely been put to the test! We do a lot of baking and we are always looking for products that will last, and this is quickly becoming one of my favorite sets! I can't wait to add more to my kitchen! Great bakeware, highly recommended!
