As you probably know the medium I use is Liquin plus a little (5-10%) Stand Linseed Oil. The addition of the oil is to slow the drying of the Liquin which begins to dry and go ‘matt’ after about an hour and a half. Generally, in oil painting the shadows are painted first so I was having the problem of the shadows drying and the tone becoming lighter by the time I got to finishing the painting.
Recently I tried ‘Drying Poppy Oil’ as a replacement for the Stand Linseed Oil in the Liquin medium mix. Even though there was such a small amount used the effect on the mixing of paint on the palette was noticeable. The paint seemed bulkier and jelly like, which was good when transferred to the canvas. As you probably noticed from my videos I do a lot of manipulating of paint on the canvas. This is why I don’t use pure oil as it gets greasy with colours seeming to slide around on top of each other and not blending together. When this is thinned with White Spirits to reduce this effect, the paint becomes thin and without body. The addition of the Poppy Oil was great, but there was a little problem. The drying time was much, much longer than Linseed Oil, even though the Drying Poppy Oil has driers added.
I intend to use Drying Poppy Oil on its own, without Liquin, and see what happens. I know that Poppy Oil is less flexible than Linseed Oil, but I don’t use stretched canvas so flexibility of the paint film is not that much of a problem for my method. However, I may be prepared to wait a long time for the painting to dry, which isn’t a problem either, if I can keep the midges from sticking to the surface. I love the paint handling afforded by Liquin, but I have a niggling worry about later varnishing issues.
