What is synthetic spinel?
Synthetic spinel, was first produced accidentally during an attempt to make a
satisfactory blue synthetic sapphire by the Verneuil process.
The addition of cobalt oxide, which seemed a logical source for the blue sapphire,
was found to give a very uneven coloration. As a result, an attempt was made to
substitute for the cobalt oxides tinctorial agents, but without marked success.
Then it was decided that magnesium oxide might act as a flux when added to the
aluminum oxide and distribute evenly the color imparted by the cobalt oxide.
The color was very even, but a study of the characteristics of the resulting boules showed
that they were squarish in outline.
Further investigation proved the material to be not sapphire but a magnesium aluminate with the structure of spinel, rather than that of corundum.
