I’ve been experimenting with caseins recently. I got some after I read the amazing James Gurney’s posts and watched his videos about the paints. (I rather wonder how much sales of caseins spiked after he blogged about them.) They’re fun!

They’re a bit like gouache, in that they are an opaque, water-soluble medium, but they seem to me more flexible. You can thin them to do washes, or use them fairly thickly. They dry to a soft matte finish. But they’re also sort of like oil, in that you can mix them wet-into-wet if you work quickly. Gurney calls them “oils on steroids,” but I’m not sure I agree. I think they’re more like gouache on steroids. But they also share a feature of acrylics: they change value once dry, generally turning darker. Since values are something I struggle with, and therefore focus on, I find the value shift annoying.

But, not enough to stop me from playing more with them!

Posting will be intermittent the next few weeks. I’m trying to finish up some larger pieces for a show, and to get ready for some trips.
