Hi All!


Hi all!

I have spent HOURS looking through the threads( I keep getting distraceted and reading other thigns;its good stuff in there!:), but now I'm tired and still was hoping for some more info. Here's my spheal:

I was told today that I can mix water into oil paints the same way you can with acrylics. That just doesn't seem right, is it?

Then I read in the threads about 'artisan mixable oil colour'---does that mean that the cooking rule of oil and water not mixing is true, except for this product?

And, would anyone mind sharing any experiences with the water-mixable oils?

Thanks!

I've gotta get off of this computer-my contacts are about to torpedo themselves out of my eyeballs!
 
Water mixable oils (Winsor and Newton - Artisan is the brand) do exist, they are formulated specially. But once you mix them with water there is no going back.
Regular oil paints are NOT water mixable.
 
Artisan Oils handle just like regular oils (no color shift wet-to-dry, long open time, etc) and you can mix them with regular oils. The more regular oil in the mix, the less there is of water solubility. The medium sold with them is walnut oil.

They are popular with those who can't tolerate turps fumes. We sell some, but not tons....
 
To alter the old saw "Oil and water do not mix." one would have to add a surfactant, a molecule that bonds with oil at one end and with water at the other.
This is what makes plastic disperse in water and in acrylic paint and these surfactants come to the surface, for two weeks, after the paint is dry. The same is likely to be true of an oil/water dispersion. The oil will still cure through oxidation and using it on unprimed paper is likely to cause complications.

You beat me to it Dave .....to extrapolate on Hugh's comment:

Just like in the kitchen, oil and vinegar don't mix unless you add an emulsifier (an egg yolk, mustard, etc).

That's why many good artists are also good cooks.....:)

Thanks for the feedbak all! I am amazed at how many 'established' artists don't know this stuff!

I know its a newer product, but so far, Does anyone know if Artisan mixable oils become porous the way acrylics do when they dry and the water evaporates?
 
Since when do Acrylics become porus when they dry? Acrylic means it is a plastic base, not really porus... infact it tends to seal the surface quite well. (Normally) (Unless you try to paint with Acrylics on top of wet oils.)
