your medium mixtures: oil to solvent?!!. . .

In the execution of representational paintin’, what medium mixtures
yas utilize: By that I mean your quantity of oil to solvent. (I’m not
particular insofar as resins and whatnot - ’Content with what I uti-
lize.)
And the second element of this query’s do yas, in fact, utilize a sec-
and medium, specifically for glazes (and, of course, those formulas)
- Those obviously need be fattest.
I’m always on the hunt for sound practices, so your greatly val-
ued.

No solvent, just walnut oil

Re: your medium mixtures: oil to solvent?!!. . .

60% sun-bleached Linseed oil; 20% Mineral spirit acrylic varnish; 20% White spirit solvent.
I can add more White spirit to this solution when I need extra fluidity. Color of this medium is water-clear. It is most colorless medium I had ever seen before.

Recently I use PET plastic bottle to bleach my Linseed oils. PET is better than glass because it is more transparent to UV part of sun light spectrum and that gives superior bleaching effect to oil.

Re: your medium mixtures: oil to solvent?!!. . .

Well, this is my ol' standby:

2 portions Water Washed Linseed Oil
2 portions Water Washed Walnut Oil
1 portion Canada Balsam
2 portions Oil of Spike Lavender

I consider this to be a bit of a medium-to-fat medium, and I use it for every single layer of my painting, whether I am glazing, or merely performing some layering. If you ignore the portion of resin (Canada Balsam), the mixture is basically one portion solvent (Oil of Spike Lavender) to 2 portions drying oil (one being Linseed, and one being Walnut).

The fat-over-lean principle is never being compromised, or violated by using one, single medium for each layer. Painting either fat-over-fat, or lean-over-lean is perfectly fine, because in neither instance are you ever applying a leaner, faster drying layer over an existing, fatter layer.

50-50 oil/solvent.
I use the same medium throughout the painting.

Re: your medium mixtures: oil to solvent?!!. . .

Often enough, I use just OMS.

Not recommended, many here will say. The paint layer will be weak, many here will say. But my layers are thin, and I often want ultra-thin lines. It's just the way my brain works.

You do whatever you have to do to get the effect you want, and then hope for the best. So far, the paint has not popped off the panel. I doubt that the pigment will go anywhere if it is held in place by varnish.

I've done SO much alchemical experimentation with various mediums! Yet in the end, simple OMS has proven to be my best friend.

Re: your medium mixtures: oil to solvent?!!. . .

This is a bit like asking what someone's favorite music is, or food, or type of socks. You will get all kinds of opinions, and not all will necessarily be "sound painting practices", some may actually give you some headaches later one - often literally!

Unfortunately there isn't an all inclusive tried and true list of the best oil painting practices that we can all defer to. It takes some searching and study to figure out what is a good practice that will work for you. And the most important thing TEST every new technique before using it in an important piece.

If I were you I would take any suggestion you see here on WC, including my own, and check known reliable sources that you trust, to see what they have to say about it.

A few shown below are ones that have consistently given sound and tested advice. Perhaps some others here on WC can offer additional reputable sites to check out.

Solvents

Solvent is unfortunately often considered necessary to oil painting when in fact is is only necessary to the type of painting which uses a soft resin medium such as damar.

Oil of Spike Lavender >>>>CAUTION - SOAP BOX STANDING-UPON AREA<<<<
In my opinion, the jury is still out on this one. Not enough long term research has been done, plus not all "Oil of Spike" you find is the real thing, many contain very little of the real deal. You will see wildly opposing comments on this material from "Safe enough to drink or rub on your face" to "Contains several quite toxic compounds" or in the middle "Less Toxic than Turpentine or OMS". One thing for sure is it does make some people very ill when exposed to the fumes and can cause rashes when it touches the skin. Some companies who sell it post warnings, others go so far as to call it Non Toxic.

Re: your medium mixtures: oil to solvent?!!. . .

1. I find that this mixture is best: 30ml gin to 10ml dry vermouth. Stirred (not shaken) with ice. Applied using a traditional stemmed cocktail glass, with olive garnish.

2. After three of those, my eyes are glazed.

The above technique does not improve my painting. However, it does improve my attitude toward such painting as I can perform.

As for the solvents, there are student grades and professional grades. I prefer professional grades, such as Sapphire with Dolin. Perhaps others would be satisfied with Gilbey's with Cinzano.

Hah.....Yeeaaahhh......Personally, I'd opt for the Sapphire. I AM a "Gin man"!

Re: your medium mixtures: oil to solvent?!!. . .

about 50/50 cold wax medium (beeswax) and walnut oil, plus >10% of the final mix with Venetian turpentine (the resin). Consistency is like very soft, starting to melt butter

Adding small amounts of odorless mineral spirits as things start thickening on the palette. I'm gonna start adding a small amount of spike lavender so the OMS, which is not really 100% odorless, smells neutral or slightly pleasant

Re: your medium mixtures: oil to solvent?!!. . .

I always find "what kind of medium do you prefer" difficult to talk about without discussing how you want your paint to behave. Someone else's perfect formula may be very well useless for me if I don't want the paint to have those same characteristics.

The last couple of paintings I've done I've used little else but Neo Megilp because I liked leaving some texture on the canvas and the somewhat quicker drying time.
