With recent innovations and research Sennelier offers a wide variety of synthetic pigments that perfectly match the performance of such ancient mineral pigments such as Lapis Lazuli and Cinnabar.

Yet at the same time Sennelier still mines the earth for minerals and other natural elements from traditional sources - pigments like clays and iron oxides used in ochres and the preparation of burnt earth colours from calcified soil.

At the dawn of the 21st century, Sennelier still keeps a watchful eye on the pigments selected for it's lines of artists' quality oils, oil sticks, watercolours, soft pastels and oil pastels. These very same pigments are available to artists wishing to master the preparation of their own colours.

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 473ml (16oz) tub of R&F Blending Medium (without the cobalt drier).youtube=xBeGfwlJRM8
