How did you get it so black? I always thought it would come out a grey color.
Actually I didn't do such a great job of dyeing this. Click on an image to get the full resolution and then look at the tips of the triangles and you'll see that they're a slightly lighter reddish color. I needed to boil them for longer. I noticed the poor dyeing during assembly but by that point I didn't want to go back and dye them again because of the work involved and they'd lose more shine.
I re-use a dye bath. I don't know what the concentration is now because I've died so many puzzles with it but I've put about 10 Rit dye packs in it. Parts boiled in it for ~2 hours it get very black no matter how smooth they started out going in. The only disadvantage to boiling this long is that the parts lose some of their reflective shine that the porcelain spheres give them.
Edit: here is an edited and highly exaggerated example of what I mean:
