||The industrial production of pottery decorated using silk-screen printing techniques requires the use of synthetic pigments, most of which represent a hazard to workers' health due to their physical and chemical properties (instability at high temperatures) and their toxicology. Consequently, these cadmium- or lead-based pigments need to be replaced by less harmful products, in particular to prevent the risk of lead poisoning. The pigments industry has developed several low-toxicity products. A test was carried out with new low-toxicity red pigments in order to determine their high-temperature stability and to compare their shades with those of red pigments used until now. It was found that these new pigments exhibit comparable shades while at the same time having lower toxicities and lower costs of production than pigments in current use.
