Rublev Oil Paint Medium Vacuum-Bodied (Extra-High Viscosity) Linseed Oil - 16 fl oz is a premium stand oil for artists who want maximum flow, gloss, and levelling with less yellowing than ordinary bodied oils. This is a heat-treated, polymerised linseed oil made from well-refined American flaxseed oil and cooked in vacuum kettles. The vacuum process produces an exceptionally light coloured bodied oil with low acid numbers, while low-temperature processing helps prevent “livering” and keeps gel formation to a minimum.
Vacuum-bodied linseed oils are widely regarded as among the finest heat-polymerised oils available because they provide a smoother, more enamel-like finish with superior brushability and holdout compared to raw, refined, or conventional open-kettle bodied linseed oils. Bodied oils also form harder films and typically yellow less than unbodied linseed oil, making them a strong choice for professional oil painting mediums, glazing, and finishing layers where you want clarity and a refined surface.
How it behaves in paint
Adding Extra-High Viscosity vacuum-bodied linseed oil increases viscosity, gloss, flow, and levelling. As the proportion increases, you will notice more tackiness and drag while brushing, along with a glossier dried paint film. Start small and adjust to your technique.
How to use
-
Start with about 10% added to oil paint or your medium
-
Gradually increase up to 30% as needed for flow, levelling, and gloss
-
Note: Using large amounts can increase the tendency of oil paint to wrinkle (alligatoring)
-
For thinning and clean-up, use turpentine, spike oil, or mineral spirits
