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
.
