The R&F Blending Medium is designed to be used with R&F Pigment Sticks and is available in jars or in stick form. Both the jars and the sticks are made from an uncoloured version of the base for the R&F pigment sticks (a solvent-free blend of Linseed Oil and Natural Waxes). Used with coloured sticks, they increase transparency, add body, extend and blend the oil paint. They are available with or without a cobalt siccative which will speed the drying time of any oil paint or paint stick. The blending medium with the added drier will have an effect on the colour of any oil paint or oil bar it is used with, so it is advisable to apply the medium to the painting support, followed by the paint.

This is a 237ml (8oz) tub of R&F Blending Medium with an added cobalt drier.
