Some of the paints that I acquired over the past few years are really useful, others, not so much. Bloodstone genuine is a reddish-black paint that granulates after application- meaning that it forms little clumps instead of drying smooth. Here, I mixed it with the beige paint in the background, if you zoom in you can see a textured, sandy appearance. I got this paint in Scotland at the end of 2018 and really liked it for awhile. The trouble is that it contains a lot of additives including a dispersant (usually ox gall) and an adhesive (gum arabic). All paints have these additives, but they add more to certain pigments especially the heavy mineral based paints so that they spread and stick to the paper. Since I got carbon black (PBk6) I stopped using bloodstone genuine in my main palette but I still like to use it in some situations.
