Welcome to dickblick
Grumbacher Cobalt Drier is the only siccative that has been scientifically proven to be the least harmful to use for fine art painting. Cobalt Drier speeds drying of oil colors and oil painting mediums.
Because it is extremely strong, Cobalt Drier should be used sparingly by applying it in drops. It should not be mixed directly into oil paints, but first mixed into an oil painting medium, which can then be added to the paint. Cobalt Drier should always be tested before using it in a painting.

I've used it for over 25 years .
from Lansing Iowa
Used as directed. Painting in thin layers,in a warm low humidity room with good air cireculation .usually dry enough to touch by the next day (some colors /pigments may take a little longer) If you over do it,adding way more than directed it will tend to dull or degrade the colors. There is no such thing as a "MAGIC" drier.

Needed Cobalt Drier for Violin Varnish
from Pleasant Hill, Cali
I was told to add a cobalt drier to a homemade violin varnish I purchased online.Only needed three drops for the 45 ml of violin varnish I bought.Going to have to buy a whole lot more of very expensive homemade violin varnish to use it up. :}

I would buy this product
By P.D.a cajun girl
from Vinton, Louisiana
I just started using this brand of drier.The one I used before you had to mix 3 different solutions together.The only thing I don't like you have to experiment to find how fast you want it to dry.
