Gouache
The gouache (of Italian Guazzo) is a Peinture with the Eau gummed, like the Aquarelle, covering and opaque. The binder or solvent used for this painting is traditionally gummed water (Gum arabic) and it is diluted with water. As for all the artistic techniques, indicates at the same time the material and the result.
Certain paintings of the Moyen-âge were comparable with “gouaches” without they having really all the properties of fast drying and opacity of the current gouaches. In the beginning, the gouache was a watercolour to which constituent was added making it possible to preserve the luminosity of painting all while making it covering (a component chalky generally).
The binders used currently in industry are binders methylcellulosic and the Glycérine.
