Gouache is a watercolor enriched  with filling material. Therefore it hasn’t the
transparence of aquarelle, but remains always soluble. That is an advantage,
when you’ll paint with fine transitions or want to change something later. I liked
this medium especially in connection with other materials or techniques. Often I
painted on paper prepared with glue and pumice flour, what gave a rough
structure. I liked also to combine gouache painting with etching.

I liked much to use gouache combined
with other materials like ink or wax crayon.
Painting  on a ground prepared with paste
and pumice powder creates a welcome
rough structure.
