The name “confectioner’s glaze” is a somewhat misleading term. It sounds a lot like “confectioner’s sugar,” which is another name for powdered sugar. You might assume that confectioner’s glaze is a glaze, like a doughnut glaze, made from confectioner’s sugar, but it’s actually made from sticklac, a material derived from insects. So, to answer the question: is confectioner’s glaze vegan? No. Confectioner’s glaze is not vegan. Confectioner’s glaze also goes by the name “pharmaceutical glaze” because it is commonly used as the hard, candy-like coating on pills.
