More casein ...
... for reference this is the Richeson " Siva " casein.
Okay. Painted for about an hour with casein. Didn't want to sketch, so I pulled up an old drawing of a cartoon drow woman guarding a doorway. So, further notes on casein.
This stuff really seems to shine in layers. If I put down two transparent layers of gouache, maybe I'm doing it wrong, but I usually get a thicker transparent layer. That's why I usually use gouache at a thick consistency. This stuff, two transparent layers equals one opaque layer. So, I love that.
It takes slightly longer to dry than gouache. I like to paint continuously with as few breaks as I can. Not a big deal, I just keep painting while its wet - maybe that's why it seems like it blends more readily than gouache. I'm refraining to say it blends better, and using the phrase " More readily" because , since I'm used to blending gouache, its a little funny how this stuff blends. Takes some getting used to - but also, its awesome. So. I spend about 10 or 20 minutes just making tertiaries since I only have cerulean, cad red deep, Naples yellow , and white. I couldn't make purple ( Always my problem with beginner sets ) so I mixed the cerulean casein with some magenta watercolor. Seems like that works fine. Later I needed a dark color so I added some cheap watercolor black to it ( I had to use black because I wanted to use the smallest amount of the transparent watercolor , so no mixing perylene and green for a better black , was the logic ) .
I can touch the surface of what I've painted, and even spray an atomizer at it with no real fears. Its not proof , but it seems more resistant.
The paper I was painting on is cheap 140lb hot press.
I'd have to say I really like this stuff and would like more, although I realize I have a problem when it comes to this kind of thing ( as in, I always want to try new art supplies ... I guess its just as bad as being content to never experiment ) . I'm gonna keep working with these primaries first though.
For negatives, I think this paint , the binder, it probably prevents the pigment from reflecting as much light. Its got a kind of dull look. That could be because of the primaries I've used , though. Also, it seems every tube is prop 65 CL . So, its fairly toxic, but I don't know why.
