Countertop heat protectors protect expensive countertops from high temperatures associated with crucibles, glassware, or other labware. Each "thermoplate" has corner feet to prevent direct heat contact with countertops. Easy-to-clean, stain-resistant surface. Stable over a wide temperature range, -392° to 1200°F, near zero thermal expansion, and insensitive to thermal shock. Manufactured from a highly engineered dark brown glass ceramic. Four convenient sizes.
