Galalith
Gararis (Ericinoid in the UK) is a synthetic plastic material manufactured by the interaction between casin and formaldehyde.
The product name is derived from ancient Greek Gala (γάα, "milk") and lithOS (ῐθθο, "stone"). It is odorless and does not dissolve in water, is biodegradable, non -allergic, antistatic, and effectively flammable.
● Discovery
In 1893, a French chemist Auguste Trillat found a means of immersing casein (liquid, especially soluble in water) by immersing it in formaldehyde.
In 1897, Hannover's printing company Wilhelm Creche was asked to develop a white, non -combustible blackboard. He was reluctant to adhere to Cazin's supporting cardboard, asking German chemists (Friedrich) Adolf Spetterer (1846-1940) to help. Plastic like the finished horn was not suitable for the original purpose, but other applications were immediately found.
● Manufacturing and use
Once hardened, it was necessary to process it into a sheet because it could not be applied to the mold, but it had the advantage that it could be manufactured inexpensive. Cutting, drilling, dyeing, and dyeing was made without difficulty, and the structure was operated to create various effects. However, other plastic at the time had no strike in terms of price, and ivory, horns, and bone products were becoming more expensive, making it a natural home in the fashion industry.
This new plastic was announced at the 1900 Paris World Exposition. In France, Galaris was sold by Galaris (Compagnie Française de Galithe) in Levalova Pele near Paris. As a result, the Jura region decided to use this material first.
Garalis was sold in plate, pipe, and rods. In 1913, 300 million liters (8 million US Garon) milk in Germany alone was used to manufacture Galaris. In 1914, Sirolit acquired a license in the UK. Rennet -derived casein produces plastic that is better than sediment in acidicin.
