Mashing, crushing

After a first step of placing the pigments in the binder with powerful mixers, the very high viscosity paste that is obtained, is treated with one or more passes through the rollers of the triple roller mills (T7 Extra Fine Gouache, Watercolour Extra Fine Fragonard, Fragonard Extra Fine Oil). The number times the paste is required to pass through the rollers, depends on the nature of the pigment grinding, and the fineness of the desired particle.

Laboratory crusher: the use of triple roller grinders for developing small scale samples that are then compared to those used in the production ensures good reproducibility of product properties between development and production.
