Heat treating El Dorado Sapphire. The Fe content is very high. One way to produce blue on Missouri River muddy greenish-bluish sapphires is to create Fe+3/Fe+3 pairs by heating at ultra high temp. in reducing atmosphere (CO2/CO or hydro/nitro). At that time, we used mostly electric furnaces with limited operating temp. to 1700oC, not enough.
