Pigments of excellent tinting strength and permanence can be extracted from the colored sands of the Negev, found in various shades like red, violet, gold and brown, G. Majewsky, head of the Haifa Technion Research and Development Foundation, reported here. He added that such pigments can be produced in large quantities for the manufacture of oil paints, plastic colors and of artists’ colors.
His report was based on research conducted in the Technion’s laboratories. The results have been favorably compared with synthetic pigments manufactured abroad and one shade–a purple brown–proved to be extremely rare and no foreign make could be found for comparison.
