This material is no longer available. Common impurities: Chromite veins and included crystals. This note was distributed by Gene Jarosewich with a number of reference materials: "Based on our experience the oxides in the standards listed below may give inferior results [n.d.l.r. Al2O3, CaO]. Other oxides in the same standards give excellent results. Al2O3, CaO Johnstown Hypersthene".
