A fine, white powdery compound that occurs naturally as the mineral periclase. Magnesium oxide is a highly refractive material that is most often used to manufacture crucibles, ceramic glazes, glass, fire brick, and magnesia cement. It was tried as an Abrasive for polishing silver by Wharton et al. (1990) but gave poor results and is not recommended. Magnesium oxide has also been used as a non aqueous Alkalization agent for paper.
