Daywalker Posted January 16, 2014 Share Posted January 16, 2014 I have been having trouble with my Winsor and Newton lamp black oil paint, and was curious if anyone else has ever encountered this? When trying to thin it for a wash, it starts to mix with the thinner, but as soon as I stop stirring it, it begins to clump back together into tiny blobs immediately. I have never had this problem with the other colors I use (raw umber, burnt umber, etc) nor a tube of Duro brand ivory black I have been forced to use (trying to save that one, as I cannot find Duro brand oils anywhere). I usually thin my oils with Naptha (lighter fluid), but have tried mineral spirits and Mona Lisa odorless thinner- both of which have no difference on how the black oil reacts. It is the Winsor & Newton Artist's Oils label, not the water based or the "Winton" label either. I bought the artist's grade hoping it would be the best? The Duro brand ivory black works beautifully, no matter how I use it. Has anyone else ever encountered this problem? I am wondering if it is a bad tube of paint? It is about one year old, so shouldn't be too old (assuming it didn't sit on the shelf at the artist's supply store for an eternity). On another note, does anyone know where I can find Duro brand oil paints? Would love to hear any thoughts or advise on this problem. Link to comment Share on other sites More sharing options...

Strange Frank! What are you using to thin it? Cheers Dave! See my post above, usually use Naptha but have tried both mineral spirits as well as Mona Lisa odorless thinner. A gentleman on another forum said he uses rubber cement thinner for these, never heard of that one! Link to comment Share on other sites More sharing options...
Dave J Posted January 16, 2014 Share Posted January 16, 2014 Ah... I missed that! Sorry Frank.. It's knock off time here... I wouldn't think it would be the Mona Lisa... Never heard of using lighter guild to thin.. Maybe a tube that's gone bad? 1 Link to comment Share on other sites More sharing options...

I too am thinking it's the paint itself, since all of the other colors seem to respond just fine. Link to comment Share on other sites More sharing options...
Administrators Fran Posted January 17, 2014 Administrators Share Posted January 17, 2014 If the paint is gloss or has gloss finish it`s normal to do that.... Link to comment Share on other sites More sharing options...
