The Verneuil process is a method of producing synthetic rubies and sapphires developed by the chemist Auguste Vernenuil in 1902. The process involves melting a finely powdered Alumina with an oxyhydron torch and crystallising the melted droplets into a boule. The boule has the same physical and chemical characteristics as corundum. Before 1940 all synthetic corundum was made in Switzerland, Germany and France..
