Borosilicate Glass vs Tempered Glass: Application Difference

Many buyers and home users confuse borosilicate glass and tempered glass when picking cookware accessories such as glass lid. Though both are common kitchen glass materials, their physical features decide totally different application scenarios for glass pot lid and kitchenware parts.

Standard tempered glass lid undergoes high-temperature quenching treatment, featuring improved mechanical strength and shock resistance. It is cost-effective and widely used for regular cookware glass lid on saucepans, stock pots and daily frying pans. Ordinary temperature fluctuation during conventional cooking fits this universal glass lid perfectly. Yet its thermal expansion coefficient is relatively high, unable to withstand extreme instant cold and hot shift.

In contrast, borosilicate glass owns ultra-low thermal expansion value and outstanding thermal shock resistance up to 270℃. This property makes borosilicate glass lid ideal for harsh working environments, including induction cooktop usage and high-heat special cookware. It can replace microcrystalline glass in exclusive kitchen equipment, which regular tempered cookware glass lid fails to match.

Based on budget and usage environment, clients can select proper kitchen glass lid. For regular daily cooking, tempered glass lid is economical; for high-temperature or frequent drastic temperature change, choose borosilicate glass lid for long-term safety.
