    Description

    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 the late 1883
    [1]
    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 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.
    Synthetic spinel
    is widely used because it is slightly softer than
    synthetic
    corundum, it can be fashioned more rapidly and less expensively. Secondly, several of the colors in which it is made are better imitation for a number of natural stones than those made in
    synthetic
    corundum
    .
