The techniques used to produce images or paintings involve colouring material added to the surface of the rock. In most cases, colouring materials are composed of mineral pigments (for instance, hematite for red motifs, limonite for yellow, kaolin for white and graphite for black).","thumbnail_url":"https:\/\/imagesdanslapierre.mcq.org\/wp-content\/uploads\/2019\/01\/comment.jpg"}
