Galalith, or ‘milk stone’ in Greek, is made from a mixture of milk proteins (casein) and gas (formaldehyde). It was originally created as a raw material for white boards until the fashion industry discovered its many strengths. Galalith is inexpensive to manufacture and lends itself to cutting, drilling, gluing, embossing and dying – ideal for mass production. Galalith can even be altered to make highly realistic-looking imitation gemstones. When polished and glossed up, a button made with Galalith can look very similar to ivory or horn.
