Artist's tempera polyvinyl-acetate colors of the "Master-Class" are produced on the basis of high quality organic and non-organic pigments and polyvinyl-acetate dispersion. They are traditional materials for painting. Due to thoroughly chosen components the "Master-Class" tempera colors suit perfectly for painting and decorative-design works. They are easily drawn on paper, cardboard, grounded and non-grounded canvas, ceramics and wood. After drying up they foam an elastic opaque indelible film.
