I'm having trouble finding a supplier for cobalt blue pigment for coloring clear alumilite. If anyone can help with providing a supplier I would appreciate it.
if you have a good art supply store they should have it. I use dry pigments myself either by sennelier or gamblin, but pure cobalt blue pigments are semi opaque and you would have to experiment with a small amount of titanium white or one of the pearl-ex micro or macro pearls as a filler.
