DANGERS of working with Strong PEROXIDE .. a read and learn article

What strength peroxide are you using? If the skull is free of grease, just submerge it without simmering. Let it sit overnight at least. If you get it into the right sort of container (like a shoebox), you can cover the skull with peroxide almost up to the antler burrs. Cover the rest of the top of the skull with white paper towels and get them under the burrs but not touching where the color starts. Keep that wet with peroxide and the whole skull will be whitened and you will not have to be retouching the antlers. Done properly, with heat, pasting can also work great and uses a minimal amount of peroxide. You get to keep using what you have for a long time.

 

You need to be using distilled water. Any iron content in tap water will start a thermal reaction you can't stop. As for the dilution, you need to decide how strong you want it and do the math. A strength of 27% is more than enough for whitening with bone. 12% will also be fine.

 

Read the article at the beginning of this post. Iron in any form and peroxide do not mix.

 

LOL. But, until someone, some time ago, posted on here that they got that reaction from using water that had a high iron content I would not have thought of that. That is a great thing about this forum. You can learn things from others.
