I did my first deer Euro mount a few weeks ago. I ordered a kit with all the ingredients and a wall plaque. I started with a freshly skinned skull and boiled it for about 30 min with 1/4 cup sodium carbonate:1 gal water. When I started, I got the water level just over the bases. After the initial boiling, I pulled it out and scraped some more.....boiled again for 20 min. Pulled the skull out and did the final scraping. I then mixed a strong peroxide with a powdered "bleaching agent" until it had the consistency of mayonnaise. I "painted" the mayo solution on the skull and let it set for 24 hrs. It turns to a light, crusty powder. I then removed the bulk of the residue with a clean paint brush...and rinsed off the rest. I was worried the two boiling cycles may have caused two problems: It foamed over really bad even on a gentle, rolling boil (thank God I did this in the driveway), and I was afraid it would bleach the bottom of the antlers....but it didn't. Second, I was afraid some of the teeth would fall out....but thankfully they didn't.
What I learned:
I wanted to buy this kit to figure out what ingredients were used, so in the future I can just buy them and not fork over $60 for a kit. From what I found on the net, 100% sodium carbonate = Arm and Hammer Super Washing Soda....not Baking Soda (maybe this is why my antlers didn't fade??). For the bleaching agent....I am not sure on this one....maybe either costic soda or Borax?? Also, I need to look at the peroxide bottle that came with the kit to see what is says....as far as strength. I haven't really looked around for "Super Washing Soda" yet, but it can't be too hard to find.
I could not be more pleased with how it turned out. All I need to do now is "seal" it with some clear lacquer.
