  • No gamsol but still fat over lean process ApproveRejectUn-ApproveSubscribeUn-Unsubscribe

    Drying Oils Environment Oil Paint Paint Mediums Solvents and Thinners
    Question
    Has any one of you experience with Lavender spike oil or Zest-it products to replace gamsol in the beginning of the painting process? I would like to work with more environment and health friendly products. Normally I use gamsol for the transparant wash and mix gamsol and lineseed for Amber underpainting. Lineseedoil in my first layer of full paint and stand oil in second layer. Than when finished a varnish. So if I start with a spike oil (which maybe does not give a stable paint layer) from the beginning in the first 2 steps, I need varnish in my second paint layer which Is not preferable. So how do I get a wash and underpainting transparant but still working or adapting all the fat over lean steps?

  • EditDeleteModerator AnswerAre you only using tubed colors? Or are you making your paints from dry pigments and medium?

  • ApproveRejectUn-ApproveUser CommentKristin, I only use tubed colors. Will mixing your own influence the painting processsteps?

  • EditDeleteModerator AnswerIn short the answer is yes.....but since you are working with tubed paints this makes things less complicated. Painting with large amounts of any essential oil can lead to the formation of a weakened paint film (we suspect this may be a possibility when using citrus oils as well but more research is needed to confirm this). That being said why do you feel you need to add varnish to your second layer? Adding varnish even in moderate amounts can increase the brittleness of your paint film, lead to yellowing/darkening, and also make for a paint layer that will remain sensitive should your painting require cleaning in the future. Why not try adding more medium (try stand oil for example) to your second layer instead? You can of course use whatever layering system you wish...we simply recommend that if you are going to use products that can create sensitive paint films that you record what you use on the back of your painting so that conservators and professionals will know how best to care for your painting in the future.

  • ApproveRejectUn-ApproveUser CommentThanks a lot. I totally understand. Im going to learn to make my own pigments with medium soon, would you please explain how this will influence the painting process. So I totally understand both ways of working. Sandra

  • EditDeleteModerator AnswerHi Sandra...making your paints can be rewarding but also quite involved. We recommend that you actually try to experience this yourself firsthand rather than read about it on this forum (or other forums). When making any oil paints by hand, you should aim for a somewhat stiff consistency after properly mulling and dispersing the pigments throughout the medium. There is a helpful chapter on this subject in Mark Gottsegen's "The Painter's Handbook" which is fairly affordable and easy to locate online. Finally, there are additional workshops hosted by both Kremer Pigments in NYC (and Germany) and Natural Pigments (California) that cover this topic should be interested in attending those.
