Rublev Colours Artist Oil Colours 50ml Cassel Earth
Rublev Colours Cassel Earth is a semi-opaque brown with good tinting strength, medium grained and, like most Rublev Colours Artist Oils, brushes "long" in the direction of the brush stroke. Rublev Colours Cassel Earth is a blend of natural black iron oxides and umber (iron and manganese oxides) from Italy and Cyprus.
Historically, Cassel earth was based on lignitic earth or earth containing as much as 60% brownish-black coal (an intermediate between peat and bituminous coal). Rublev Colours Cassel Earth is made from a blend of natural black iron oxides and umber (iron and manganese oxides) from Italy and Cyprus. This particular blend, carefully blended, closely resembles the historical pigment in mass tone, opacity, and tinting strength. Historical Cassel earth was a fugitive pigment (that is subject to fading in light). Rublev Artists Oils Cassel Earth, on the other hand, is lightfast.
Rublev Colours Artists' Oils let you experience what the old masters well understood--the unique characteristics of pigments. The pigments used by old masters in their paintings were ground from natural minerals and earths, fermented in dyer vats and concocted in alchemist laboratories. Rublev Colours Artists' Oils give you the same pigments used by the old masters prepared with linseed oil as ready-made paints.
Rublev Colours uses natural pigments or historical reproductions of pigments used by the old masters. Rublev Colours Artists' Oils are formulated to maintain the unique characteristics of each pigment in oil. The character found in each tube of these oil colors is unique due to the pigment inside, giving the artist nearly limitless choices of texture, opacity, consistency, tone and hue.
Rublev Colours Artists' Oils do not contain additives, such as fillers, driers and stabilizers--simply pigment and oil. Refined linseed oil is used in the paint sometimes with a small amount of heat-bodied linseed oil. Stabilizers, such as stearates and waxes, are not added that diminish the individual effects of pigments in oil. Therefore, you will find different consistencies from color to color due to the individual pigment characteristics, and an occasional bit of free oil. Some colors brush out long, others short and buttery and still others are thixotropic.
