Also called Pierre de Lait in France – a direct translation from the Greek (Milk Stone). In 1891 Trillat, a researcher in the Pasteur Institute, discovered that mixing casein and formaldehyde produced a hard stable material. This led to the invention of galalith by Spitteler and Hirsche in 1898 who patented it and took over the name. It was used to make a wide variety of objects: buttons, pens, door knobs, office and perfumery articles. It reached its peak in 1930 with millions of kilos manufactured in the Jura... until it was superseded by Bakelite.
But today there are designers getting interested again in this product.
