…properties make it a popular choice for fusions and fluxes in analytical chemistry and chemical processing. Unlike crucibles made from many other materials, zirconium crucibles are highly resistant to corrosion; do not require handling with platinum tipped tongs; can be cleaned with most common…

A high quality porcelain crucible. The porcelain is uniform in thickness and dense which allows stable mechanical strength and little permeability. When properly used, the glazed pieces can withstand temperatures of 1050 degrees centigrade. The crucibles are glazed on the inside and outside surface.
