Discover the principles of glass chemistry. This interactive shows you how glassmakers mix together ingredients to make what’s called “glass batch” and allows you to explore what mixing certain elements together can do. The basic ingredients of glass are elements found on the periodic table: silicon dioxide (silica), sodium, and calcium.
Adding different elements can change the color and properties of the glass. For instance, iron can produce greens. Iron and sulfur can produce ambers and browns, copper can produce light blues, cobalt produces very dark blue, manganese can produce shades of amethyst color, tin can produce white, lead antimony can produce yellow and various metals produce reddish glasses.
