Verneuil process: Method for producing synthetic rubies and sapphires.Beforeall synthetic corundum was made in Switzerland, Germany, and France.
The vivid colours of corundum gem varieties, such as ruby and sapphire, ariseThe process of intervalence charge transfer (essentially continual swapping ofelements (only ~0.wt% Fe and Ti) are needed to produce the vivid blues.
Historically, the most famous and prolific production has been from Myanmar (nemore difficult process, flux growth, is also used to synthesize gem corundum.
“Producing the stones was a manual process initially,” says Mr. K.P.The corundum was being produced by the Indo-Swiss Synthetic Gem

The Verneuil process, also called flame fusion, was the first commercially successful method of manufacturing synthetic gemstones, developed in the lates by the French chemist Auguste Verneuil. It is primarily used to produce the ruby and sapphire varieties of corundum,
Rubies and sapphires are both composed of corundum, which is thethe first commercially successful application of the flux process of ruby manufacture.
The heat generated from this procedure melts the alumina feedstock.Brown Fused Alumina is a dense material produced from bauxite raw material. The end
