Pharmaceutical glaze is an alcohol based solution of various types of food grade shellac. When used in food and confections, it is also known as confectioner's glaze, resinous glaze, pure food glaze and natural glaze. It is also known colloquially in the manufacturing world as beetle juice due to shellac's derivation from the lac insect Kerria lacca (which is not a beetle, but a scale insect).
