Natural mineral pigments
We use only natural mineral pigments as they do not evaporate from a wood surface, are insoluble in water, do not have any smell, do not fade in the sun and are absolutely safe. Usually they are natural oxides of iron, zinc, chrome, titanium and other metals. They are contained in Earth crust (clay, sand and other minerals). Because their insolubility in water and natural origin, in common conditions of use, they do not cause any harmful action on humans.
