    About:
    The Verneuil method or Verneuil process or Verneuil technique, also called flame fusion, was the first commercially successful method of manufacturing synthetic gemstones, developed in late 1883 by the French chemist Auguste Verneuil. It is primarily used to produce the ruby, sapphire, and padparadscha 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 crystallizing 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.
