In the North-Bohemian Brown Coal Basin a lot of various raw materials occur next to brown coal. Inorganic pigments bounded to the weathering zone of volcanic rocks are one of the little known raw materials. The Fe minerals, hematite and goethite are the carriers of the colour which, according to the share, create the colour from red (hematite to ochre (goethite).. Mouldered rocks expose to the South from Chomutov in the surroundings of the Hořenec community and create the deposit of purpurin with the estimated reserves of 12 million m3.
