spinel in situ versus preformed clearing the mythfoundry ladle maintenance and troubleshooting
Spinel Quality FactorsGIA
Spinel has been making a name for itself over the last couple of decades and demand for fine stones well exceeds supply. In fact spinel is in great demand among gemologists and gem connoisseurs. This has to some degree closed the spinel vs. ruby-and-sapphire price gap. Blue spinel hues range from violet blue through very slightly greenish blue.

A family of magnesite-spinel brick has been developed by combining the constituent raw materials in various ways. Some magnesite-spinel brick are made by adding fine alumina to compositions composed mainly of magnesia. On firing the fine alumina reacts with the fine magnesia in the matrix of the brick to form an in situ spinel bond.

On firing the fine alumina reacts with the fine magnesia in the matrix of the brick to form an in situ spinel bond. An alternative is to add spinel grain to a composition containing magnesia. One of the principal benefits of combining spinel and magnesia is that the resulting compositions have better spalling resistance than brick made solely
