Copper Oxide Black (Pottery Colourant) Oil-Soluble Fragrances for Cold-Process Soaps Hydrosols are a by-product ofColourants can be added to glazes to get the desired coloured effects. Unlike stains, colourants react differently in each firing. A wide spectrum of colours can be achieved by mixing them with other colourants, opacifiers & stains. Name: Copper Oxide (CuO) Appearance Colour: Grey~Black Form: Powder, Inorganic Compound Recommended Usage: In Slips: 2% 8% In Glazes: <5% If concentrations above 5% are used, glazes often change to a metallic pewter black.
