I just made a stupid mistake. I mixed medium into my paints yesterday, and then today, I though they needed some more in them so I added SDM to all of them-including the titanium white!
Yesterday, for the titanium white, I used the medium specifically intended for it (only stand oil, venice turpentine, refined linseed oil and odourless mineral spirits), but today I added probably 5mls of SDM (which had stand oil, venice turpentine, refined linseed oil, odourless mineral spirits and clove oil). There is probably 30ish mls of white SDM and about 5mls of the other SDM. Does this matter? I have run out of venice turpentine so I will not be able to make any more SDM.
I also accidentally added this discussion to the wrong section and am not sure how to change it the the supplies page. Sorry.
