Suitable Temperature Range of Different Kitchen Glass Materials

Choosing the right glass lid relies heavily on knowing temperature tolerance of common kitchen glass materials. Different raw materials decide the working limit of your glass pot lid, directly affecting service life and safety during high-heat cooking.

Ordinary soda-lime glass, rarely made into qualified cookware glass lid, withstands only −20℃ to 60℃ and cracks easily under sharp temperature swings. Most mainstream tempered glass lid is soda-lime after thermal strengthening, supporting steady working temperature from −30℃ up to 150℃; it survives regular cooking heat but cannot endure instant extreme cold pouring onto scorching hot kitchen glass lid.

Borosilicate glass stands out for ultra-low thermal expansion. Premium borosilicate universal glass lid safely works between −40℃ and 300℃ and resists drastic hot-cold alternation without cracking, perfect for frequent high-temperature cooking and induction cookware.

When purchasing wholesale or household glass lid, match material temperature property with your cooking habit to avoid unexpected breakage and kitchen hazards.
