"The Verneuil process, also callled flame fusion, is a method of manufacturing synthetic gemstones, developed in 1902 by the French chemist Auguste Verneuil. It is primarily used to produce the ruby and sapphire varieties of corundum, as well as the diamond simulants rutile and strontium titanate. The principle of the process involves melting a finely powdered substance using an oxyhydrogen flame, and crystallising the melted droplets into a boule. the process is considered to be the founding step of modern industrial crystal growth technology, and remains in wide use to this day."
