Heat-resistant glass and normal glasses are different! Unlike other glasses, heat-resistant glass use material that contains strong heat resistant properties which could withstand sudden change in temperature. Heat-resistant glass is produced in temperature above 2700F which makes it harder to manufacture.
Heat-resistant glass can withstand sudden change in temperature, thus it could be used not only in a refrigerator, a microwave and a dishwasher but also in a 750F conventional oven. Normal glasses or tempered glasses may, with small scratches could be broken and scattered when there is a thermal or physical shock. LOCK&LOCK BOROSEAL uses Heat-resistant Glass for more safety.

- Excellent airtightness with the 4-side locking system
- Cooking in oven, or use it as bakeware (without lid)
- Salt and oxidation resistant
- Stain and odor resistant
- Freezer to microwave at once
