The glassmaking industry for both virgin and recycled glass uses various additives to obtain specific characteristics to meet end-use requirements. Among these, the colouring of both flat glass and containers is useful for creating a barrier against UV rays.
Veneta Mineraria produces different types of micronized mineral fillers designed to be used for colouring glass. Iron-sulphur based pigments such as pyrite lend pharmaceutical glass its characteristic amber colour. Iron oxides under oxidizing conditions create the green UVAG (Ultra Violet Absorbing Glass) colour generally used to protect oil from damage caused by exposure to light. With our extensive range of mineral fillers and capacity to develop new products, Veneta Mineraria can meet any requirements, applications and working conditions you may need.
