Notice: these values are only for pigments in a binder such as linseed oil. Some manufacturers are adding
driers or other additives into their formulated paints. Than the values are different from the table above.



Basically, all colours will become touch dry in 2 - 12 days. The different drying rates are due to the different reaction of each pigment when mixed with oil. You can change the drying times of the colors by adding a vast range of additives to them. Manufacturers try to produce an average dryingtime troughout their product range.
That can be oils for faster drying or oils for slowing down the drying time; or you can add
siccatives (driers) only to speed up the drying times rapidly.
There is also the possibility to influence the appearance of the colors when they are dry. With
additives you can make them high glossy or flat matt.
