This high-temperature resistance quartz test simulates the impact of placing a hot pot directly on the quartz stone countertop without using a heat-resistant pad. Gelandy quartz stone countertops have excellent high-temperature resistance and can withstand temperatures ranging from 180 to 300°C. Therefore, the test does not affect the Gelandy countertop. However, to ensure the longevity of the countertop, it is recommended to use a heat-resistant pad.
