Hello all. Hope this is the right board to post this question, new here.
I’m trying to figure out how casein behaves, everything I’ve read seems to pitch it as being like a “matte acrylic”, or being like a ‘creamier’ gouache.
The only consistent thing seems to be that it needs to be used on a stiff support like board moreso than paper, which I don’t mind.
(If It were as easy as driving down the street and grabbing a tube to play with, I would have. But it seems I can only find full sets online for a decent price and no sellers locally.)So I’m a little gunshy since I don’t want to ship it in and realize it doesn’t behave significantly different from gouache.
Some say the surface is absorbent enough to work on with watercolor, others say that water washes could rewet the casein paint? Is it just *harder* to rewet than gouache? (ie. vigorous scrubbing vs. light wash)Or is it just a different binder with identical working properties? Could there be an advantage to bringing it into play with my gouache and watercolor pieces? Could it lift? Will it sit well on top of gouache/watercolor or vice versa?
May 21, 2017 at 1:47 pm #1269532These are great questions, Milkboot. I’ve never used acrylics, but do a lot of watercolor, and recently gouache.
I strongly suggest you request to have a moderator move this (or just repost it yourself) to the “Casein Gouache and Egg Tempera” forum. There are a few members doing neat work in casein that I’m sure will respond helpfully if they see your post.
I got a decent selection of shiva caseins over the holidays and will be making them a centerpieces of plein air efforts this spring/summer. I have some comments/observations I’d make here, but I’m a total tyro at this point, and am very interested in what experienced users will have to say.

If you do a search (like on Google) for difference in casein & gouache, you’ll find some opinions like from James Gurney. He uses all media that you mentioned & here’s a link to his first use of casein:

June 16, 2017 at 7:31 pm #1269531I have used casein. It is not that similar to gouache. The paint has a distinct thickness to it, and the strokes tend to be shorter and sharper-looking for lack of a better term. One tricky thing is that each stroke tends to stand on its own more than gouache and oil (in these blending is more easy). It is very high-key (light and velvety), sort of like gouache, but I would say that is even higher key, if that is possible. The most obvious thing is that the ultramarine blue is almost like a cobalt blue in other media. Many people don’t like this, but I bought caseins since I noticed that my oil paintings sometimes look a bit dark in rooms that are not well lit. Casein paintings definitely look brighter on the wall, but I do find myself using black more often in order to make the darks dark enough.
