I have a large body of work that I need to complete, and I had been using Stuart Semple's Black 2.0 and Black 3.0. It seems he's out of stock, at the moment, and I'm on a deadline. I have not done much experimentation with other matte black media, so I'm hoping I can learn from some of the community's experience.
What are some good alternatives to Black 3.0, Mussou Black, and the strictly-licensed VantaBlack, for a very dark, very matte, black paint? Each of these is out of stock or prohibitively expensive.
I'm more familiar with acrylic paints, and their fast drying time is helpful, but I'm not opposed to other media, so long as I can get an impasto texture from it, and it's not prohibitively difficult to work with.
Is it possible to get similar results from a high-quality PBk6 (Carbon black) or PBk7 (Lamp Black) acrylic paint? I presume that Semple's black is little more than carbon in a matte acrylic medium, but there's clearly something about it that you can't reproduce with Windsor-Newton and a matte spray finish... or am I mistaken?
EDIT: For others' reference, I stumbled across this guy's YouTube video, which shows the process of making black paint to be (unsurprisingly) substantially more involved than is immediately obvious. Even knowing what he does, he was not able to get a pure black, and it took an enormous amount of work to grind it to a usable consistency: (Channel: "The Alchemical Arts" Video title: "Not so simple Charcoal Black pigment!")
