An innovative process is described for production of coloured powder cosmetic products. The process comprises forming a 'slurry' (1) consisting of a powder cosmetic product and of water and/or solvent, pouring the slurry in a container (2) of anti-adhering material with shaped internal bottom (3) and smooth internal sidewalk (4). The slurry (1) poured into the container (2) is subjected to slight pressing by means of a plate (5) superimposed thereon. The process then provides freezing the slurry (1) inside the container (2) with the plate (5) arranged to close the top of the container (2), extracting and overturning the assembly consisting of the slurry (1) and of the plate (5) and putting such assembly (1, 5) into a cooking room.
