The Lock & Lock BOROSEAL 10-Piece Set/5-Containers
Heat-resistant glass and normal glass are different! Lock & Lock uses the best materials including borosilicate glass.
Difference in raw material Lock & Lock glassware is made of borosilicate glass which withstands high heat and sudden cooling, which allows you to use it safely in the oven, micro-wave and dishwasher.
Difference in manufacturing process Heat-resistant glass is produced at temperatures above 2700°F, which makes it harder to manufacture. Lock & Lock glassware also contains borosilicate, which makes it capable of withstanding sudden change in temperature.
View this video to see how borosilicate glass differs from glass made from soda lime (the typical glassware you find in the US).
Difference in use 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 750°F conventional oven.
Safer with 100% heat-resistant glass Normal glass or tempered glass may, with small scratches, shatter when there is a thermal or physical shock. LOCK&LOCK BOROSEAL uses Heat-resistant glass providing improved safety and durability in its glassware.
