To create different colours and textures, maki-e artists use a variety of metal powders including gold, silver, copper, brass, lead, aluminum, platinum, pewter, as well as their alloys. Bamboo tubes and soft brushes of various sizes are used for laying powders and drawing fine lines. As it requires highly-skilled craftsmanship to produce a maki-e painting, young artists usually go through many years of training to develop the skills and to ultimately become maki-e masters. Kouami Douchou (1410—1478) was the first lacquer master linked to specific works. His maki-e works used designs from various Japanese contemporary painters. Kouami and another maki-e master, Igarashi Shinsai, were originators of the two major schools of lacquer-making in the history of Japan.
