Grumbacher Cobalt Drier
Description:
A drier makes oil paint dry faster by accelerating oxygen absorption. This ages the paint film and can make it become dark and brittle, encouraging cracking. Problems are increased by overuse. All driers should be used very sparingly, and are not recommended for fine art use.
This cobalt linoleate drier is made of cobalt salt cooked in linseed oil. Considered to be the most reliable of driers.
