Abstract
Process for the colouring of granules of stone materials which comprises providing a quantity of stone granules having a particle size between 2 mm and 2 cm, thorough mixing of the granules with an impregnating agent formed from a solid phase comprising at least one organic colouring agent or pigment and a solvent phase until the largest granules are completely coloured, and evaporation of the solvent phase from the granules.
