Flame Fusion aka the Verneuil process - 1902

Postby Horse Feathers » December 17th 2010, 10:02pm

I found this interesting, Flame Fusion aka the Verneuil process dates back to 1902 as a process to make Synthetic Gemstones including Sapphire

I assume Invicta patented the commonly used name, but stating this process as new and unique is far from the truth.

===============================================================

The Verneuil process, also called flame fusion, was the first commercially successful 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.

================================================================

This realisation, along with the availability of the recently developed oxyhydrogen torch and growing demand for synthetic rubies, led him to design the Verneuil furnace, where finely ground purified alumina and chromium oxide were melted by a flame of at least 2000 °C (3,600 °F), and recrystallised on a support below the flame, creating a large crystal. He announced his work in 1902, publishing details outlining the process in 1904.

You can't patent a name. They trademarked an industry term to merely add more sizzle to a product inferior to sapphire, in order to replace it in their line as a cost saving measure.

Your correct, I incorrectly referred to it as a Patent, I know better. It's Invicta tradition to spin a cheap replacement as superior an unique, actually the basis for the brand
