Pharmaceutical glaze
（重定向自Confectioners glaze）
Pharmaceutical glaze is an alcohol-based solution of various types of food-grade shellac. The shellac is derived from the raw material sticklac, which is a resin scraped from the branches of trees left from when the small insect, Kerria lacca (also known as Laccifer lacca), creates a hard, waterproof cocoon. When used in food and confections, it is also known as confectioner's glaze, resinous glaze, pure food glaze, natural glaze, or confectioner's resin.
