Rublev Oil Medium Botticino Marble Dust (Medium) – 1kg is a high-quality, medium-coarse marble powder imported from the renowned Botticino deposit in Italy. Ground to a particle size of 0–0.7 mm, this marble dust retains its crystalline structure, making it ideal for preparing traditional painting grounds, fresco intonaco layers, and modifying the handling qualities of paints.
Composed primarily of calcium carbonate (98.75%), with only trace levels of magnesium carbonate, silica, iron oxide, and alumina, Botticino Marble Dust offers both purity and consistency. Its natural crystalline form adds texture, tooth, and body to paints and mediums without tinting color, while also producing durable, archival grounds.
Common uses include:
-
Grounds & gesso – increases tooth, durability, and absorbency.
-
Paint modification – enhances texture and handling without altering color.
-
Fresco – filler for lime plaster in the intonaco layer.
-
Surface preparation – for traditional painting and restoration techniques.
With a hardness of 2.8, specific gravity of 2.7, and dry brightness of 98, Botticino Marble Dust (Medium) provides excellent performance for both historical and modern art practices. Supplied in a 1kg bag, it is part of the trusted Rublev Natural Pigments range
