    摘要： A black pigment substantially free of objectionable transition metal materials is disclosed. This pigment is particularly useful for coloring glass since the absence of the transition metal gives it excellent recycling properties. The pigment is an alkaline earth (preferably strontium) iron maganese oxide material as specifically defined the in the present invention.

    摘要： The invention provides new stains which fire to a red-brown color for coloring ceramic compositions. The stains comprise Fe2O3 and/or an Fe compound which forms Fe2O3 on firing, in uniform distribution in a pulverulent matrix based on an oxide-like and/or silicate-like material which is amorphous to X-rays to the extent of at least 50% and has a specific surface area (BET) of at least 40 m2/g, and are obtainable by bringing the constituents into intensive contact together. The matrix preferably comprises 80 to 100% amorphous SiO2 or SiO2-rich silicate with a BET surface area of 90 to 300 m2/g and 0 to 20% of an auxiliary substance, such as silicone oil. The stains can be prepared by intensive dry grinding.
