Archival Odourless Mediums and Solvents are based on fast drying alkyd resins which out perform ‘traditional’ mediums and are better for health. They evaporate much more slowly than turpentines so that very little vapour is generated during a painting session.

Archival Fat Medium

Alkyd Based - Fast Drying

This syrupy, heavy bodied liquid medium contains high solids.  It promotes faster, more thorough drying of oils, increasing gloss and flow for enamel-like effects.  It can also be added to Lean Medium if a more glossy effect is desired.

Recommended for experienced painters who work all day on the same painting.
