This 150mL squat-form crucible is made from porcelain, glazed inside and outside except at the base. The crucible stands 52mm tall and is designed to withstand high temperatures for heating, calcining, and ashing applications. The squat form provides a wide opening and low center of gravity for stability during heating. The glazed surfaces resist chemical attack and staining, while the unglazed base allows direct heat transfer from burner flames and furnace elements. Suitable for chemistry experiments involving high-temperature reactions, gravimetric analysis, and ignition of precipitates.
