How do you use painting medium?

[Michele Rushworth]

The more you read about the use of mediums the more you'll find that there are as many approaches as there are artists.

I trust the input of artists like Virgil Elliott who work with the ASTM, studying longevity of artists materials. He recommends a philosophy of "less is more" with mediums. Fewer extraneous ingredients and less of whatever you do use. He especially cautions against including any varnish in the paint layers which causes dramatic darkening over time (and that includes all the mastic varnish in the Maroger's).

I use paint and a bit of linseed sometimes. That's it. I can paint alla prima, glaze or scumble with different proportions of oil and paint, but either way, I don't use much linseed.

I will sometimes rub a very thin layer of it into any sunken in darks and then wipe much of it off. It does restore the gloss and depth of color in the darks and it allows me to blend wet edges, but I use this technique only once in a while.

Hi Michele,

I hope you don't mind me quoting you from over half a year ago! I was reading through old posts after doing a search on scumbling and I came across this post.

I am wondering how you get your soft edges? I'm thinking specifically of your recent work "Flowergirl", the edges were so lovely and soft. Instead of me assuming I could know how you did this, could you explain your method of getting those soft edges? I would have thought you used lots of layers with linseed oil?

I am just starting a painting and I'm going to try out the 'layering' method, layer upon layer of scumbles over my 'underpainting'. So, before I start my scumbling, I'm reading about how it's done.

Any information is greatly appreciated,

Thank you,

Joan

I do generally "oil out" dry paint layers with a 50/50 mixture of linseed and mineral spirits nowadays, and wipe as much of it off as I can. Then I put on the new layer of paint.

I "oil out" mostly so the old colors come up to their original saturation. Then I can match the new colors to the old paint more accurately.

Then I paint on the new layer and blend one color into another with a fuzzy old sable brush, and then go over it with a synthetic fan blender, to get the soft edges. I put relatively thin layers of paint on the canvas (compared to what I used to, anyway!) because thick paint is much harder to blend.

Most parts of my paintings typically have one to four layers of paint on them by the time I'm done.

Thank you Michele for your thorough answer. I just learned a tough lesson when I put too much paint on my last portrait. It was very hard to blend, what a mess, so I scraped that off after working on it for 2-3 days. So now I'm experimenting with thin layers.

I've read a lot of posts about 'oiling out' and I am wondering why use the linseed oil and the mineral spirits instead of just straight linseed oil?

Of course, when I went to the art supply store to buy linseed oil last week they had cold pressed linseed oil and refined linseed oil! So I came home and found a post by Marvin about what the heck the difference is. After learning what the difference was I am prepared to go buy the cold pressed linseed oil. Should I be mixing it with mineral spirits? Hmm.

Thanks again,

Joan

You want as little linseed as possible in your paintings, to minimize yellowing. Just enough to have good binding with the pigments.

Oiling out with 50/50 linseed and mineral spirits helps me keep the oil layer thin, as the mineral spirits just evaporate away.

Michele,

Now I get it!

Thank you,
