Re: Skull of the week Pot Belly pig 8/21/09 Defeat on 10/14 Oh, I've done the tea and coffee bit before. I have tons of black, loose tea too. Trouble is, the color is not the same. This is more of an orange shade. Cyclone, I'll see about finding some Iron Out. I just have a concern of bone damage. I'll round up a test skull and see what happens with a soak. I did seal the pig skull but it's easily removed with straight acetone. It's definitely not grease. Matter of fact, it seemed to react with the ammonia and got darker. Wasn't an effect I was expecting.
