Chemcial Question for Taxidermy Related Project

I am quite interested in the articulation of the bones of animals. I plan on using small game (squirrels, frogs) to begin with, and I will probably donate them to my Biology teacher, since she loves skeletons.The process of defleshing and whitening the bones of the animal is fairly straight forward - soak the carcass/skeleton in chemical baths and take it out when it's done. The chemicals needed for the process are what's going to be hard for me to obtain.I need a 0.3% solution of sodium carbonate. Sodium bicarb is extremely easy to come by, but I've never seen sodium carbonate. I've heard it is used to raise the pH in pools, so I'm guessing a pool store would carry it. But, would it be possible (practical) to make it? Is there a way, using household chemicals, to produce sodium carbonate? I don't need very much.Secondly, I need a 20% solution of hydrogen peroxide. I only have a 3% bottle. I've heard H2O2 is some pretty dangerous stuff. Again, is it possible for me to buy/make it? Would freeze-purifying it work?Thanks for any help, and if I get this to work out, of course it'll all be turned into an Instructable.
