Rublev Colours Disperson Luberon Burnt Sienna - 2 fl oz

When sienna earth is calcined (roasted) at high temperatures, it loses its water content (hydration), and it becomes burnt sienna. Luberon Burnt Sienna is from the last remaining European company operating the ocher deposits in the French quarries of Gargas and Rustrel nested in a 12-mile-long enclave in the heart of the Luberon Mountains, the ocher country.

Dispersions are pigments dispersed in water ready to be mixed with water-based mediums. These dispersions are specially made for traditional painting mediums, such as egg, casein, fresco, watercolors, and distemper (glue tempera). They are also ideally suited for use with gesso for making 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 and natural mediums. Unlike other pigment dispersions 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.

You do not have to hassle with powders, grinding pigments with expensive tools, and calculating pigment-binder ratios to make water-based paint. They make adding the right amount of paint binder simple and easy. For example, preparing egg tempera has never been easier because the dispersion makes measuring the right amount of pigment manageable—you add egg and stir—there's no guessing how much egg to add to the pigment.
