Valli Colured Quartz is a natural quartz that is washed, dried and then artificially coloured.
The dyeing process uses pure pigments, natural oxides and synthetic resins, which give the granule a high resistance to water and light. Valli Granulati has an archive of over 1500 colours and is capable of producing endless customised colours, in several grain sizes.
Valli Coloured Quartz is employed in the following fields: resin floorings, wall cladding, synthetic grass fields, locations for events, showcases decoration, aquariums and decoration. It is a completely non-toxic quartz obtained with a process that does not alter the pH values and is perfectly compatible with plants and animals.
