Rublev Oil Medium Pumice Fine Grade (1kg) is a near-white, finely milled volcanic glass with multiple applications in oil painting, grounds, and fine art preparation. When added to oil or acrylic paints, pumice increases body, introduces a fine texture, and gives colors a matte appearance without altering their hue.

This fine grade pumice is ideal for:

• Paint modification – adding subtle tooth, matte finish, and texture to oil and acrylic paints.

• Grounds & gesso – blending into chalk or gesso grounds to create a uniform, toothy surface ideal for drawing or painting.

• Polishing & abrasives – used to smooth wood, substrates, and traditional grounds without discoloration.

Mined from volcanic deposits in Española, New Mexico, this pumice is rigorously processed, milled, and classified for consistent particle size and purity. Its clean white color ensures it will not tint or discolor grounds, making it the perfect additive for artists seeking control, archival safety, and professional results.

Packaged in a 1kg bag, Rublev Pumice Fine Grade is part of the Rublev Natural Pigments range—trusted by artists worldwide and now available in Australia.
