My mars black is drying too quickly. I've got some clove leaf oil but am unsure how much to use. My experiments haven't worked! The -control- samples didn't seem to dry half as fast as the paint on my actual paintings and after a week are still wet... that's a concern. On the other hand the samples with the clove oil don't seem to be drying that much slower.
Anyhoo; wikipedia says a drop per paint nut, but I have small nuts and boy do I have a big drop! At the moment I'm using about half part of a drop like 2/3 of a human tear that drips freefall from your face (this is not very scientific!) in about 3ml of paint (based on a teaspoon being 5ml).
Can too much cause problems? Like months/years to dry? Experience of clove disasters and triumphs, please
