Rublev Colours Oleogel is a solvent-free oil painting gel medium that boosts transparency for glazing, improves flow and brush feel, and helps you build controlled layers without making paint runny. Made from linseed oil thickened with pyrogenic silica, Oleogel has a clear, pale amber appearance and a naturally thixotropic (buttery-yet-structured) body that keeps strokes where you place them.

Use Oleogel to:

• Extend oil colours while keeping colour strength and body

• Create luminous glazes and soft transitions with better control

• Increase transparency in dense colours (even whites) without thinning the paint

• Build impasto that doesn’t sink in (add pigment or extenders for extra stiffness)

Oleogel contains no solvents and no added driers, making it a reliable choice for traditional oil painting workflows—ideal for artists wanting a cleaner studio setup and more predictable handling.

Size: 50ml tube

How to use

Mix a small amount into your paint on the palette (a palette knife gives the smoothest blend). Use sparingly—up to 25% by volume is a good guide. Apply in thin, controlled layers to avoid wrinkling and excess gloss.
