What are the directions for the glass bakeware?

Borosilicate glass is durable and able to withstand temperature changes, so it can go from a 0°F (-18°C) freezer to a pre-heated 450°F (232°C) oven without shattering. However, like all glass, it’s still breakable, and should always be handled with care. While perfect for putting a thawing dish in the oven, putting hot Bakeware immediately into cold water may still cause it to crack or break. Dropping or hitting it can cause it to break, and you should always inspect your dish for chips or cracks before using. 

To make the most of this high-quality glass, read and adhere to the following warnings. Keep away from direct flame, including broiler, stovetop, grills or toaster ovens. Let hot Bakeware cool before placing in the sink or immersing in water. Keep hot Bakeware off cold or wet surfaces, OXO recommends placing hot Bakeware on a trivet, dry potholder or dishcloth. Do not use if chipped or cracked. Always handle Bakeware with oven mitts or pot holders when removing hot glass from the oven or microwave.
