What is the luster of hard candy?

Hard candy typically exhibits a vitreous or glassy luster, which means it has a shiny and reflective appearance similar to glass. The vitreous luster of hard candy is a result of its amorphous structure, where the molecules are arranged randomly and do not form a regular crystalline pattern. This disordered arrangement allows light to be scattered and reflected evenly from the surface, giving hard candy its characteristic glossy shine.
