Even the artists who created a painting of astonishing dimensions in the caves of Altamira (Cantabria/Spain) knew this and therefore took no risks more than 10,000 years ago: for their numerous drawings they used the proven iron oxide pigments they extracted from the natural deposits in the area. Only in this way they achieved, that we can still admire the beauty of this huge painting today. Even today, iron oxides are still the most widely used colour pigments worldwide. In their own colours red, yellow and black, they can be used in almost any application thanks to their extraordinary chemical resistance and light fastness. With the modern, synthetically produced iron oxides, we get also the brilliant colours with high colour strength and colour fidelity at favourable conditions. A material which even today, after thousands of years, hardly anyone can renounce.
