The other day I went to a demonstration by a representative of the Gamblin paint company. Got some free samples, including a medium called Galkyd. It's got interesting and different working properties, but it doesn't smell nice. They're making all these substitutes for turpentine and damar, but they're from petroleum, so that's non-renewable... anyway, this fellow said one shouldn't use damar in a medium... but my teacher recommends it. And Gamblin makes a damar substitute, so the representative might be biased... In whatever case, learned a bunch of color theory and like I said, free samples!
