A medium based on vegetable oil and natural resin that allows for different thicknesses and reliefs.
It is a paste that is sturdy yet light to use with the brush.
For layers of a few millimeters or more, it is essential to mix Van Eyck medium or oil paint into the impasto medium to make the paste more flexible and reduce the risk of cracking.
The medium dries matte when gum turpentine is added.
Do not add a siccative.
