Rublev Colours Dispersion Blue Ridge Violet Hematite - 2 fl oz

Natural red iron oxides are opaque, absolutely permanent and have excellent covering power. They are strong absorbers of ultraviolet light. The best bluish shades are called Indian red; the yellowish shades, light red, English red, and Venetian red. Formerly there was much confusion in the nomenclature of the red oxides; the terms given in this list are those specified in the ASTM Standard.

Dispersions are especially made for use with traditional painting mediums, such as egg tempera, casein tempera, fresco, watercolours and distemper (glue tempera). They are also ideally suited for use with gesso to make toned grounds for drawing and painting. Pigment dispersions from Rublev Colours contain only naturally-derived ingredients, in addition to pigment and water, making them ideally suited for traditional mediums. Unlike other pigment dispersions that are typically made for acrylic medium, Rublev Colours Aqueous Dispersions do not contain coalescent solvents, artificial dispersing resins and other additives that interfere with natural mediums.

Aqueous Dispersions make preparing traditional mediums easy; you do not have to hassle with powders, grinding pigments in medium and calculating binder ratios to make water-based paint. They make adding the right amount of paint binder, such as egg yolk, a no brainer because the right amount of water is already contained in the dispersion, simply add egg yolk.
