R&F Handmade Paints Pigment Stick Blending Medium with Drier, 8 oz.

Blending medium is ideal for glazing colors, and can be worked directly into a color to increase the color's transparency or to blend colors together on the surface. This medium contains a small amount of Cobalt Drier, added to speed up the drying time of your layers. The use of a Cobalt Direr can affect color - work colors on top of it after it has been laid down on the surface.
