Bronzing Wax Objects

We have been asked to bronze a set of "wax hands." It is our intent on filling the hollow portion of the hands with a liquid substance that will harden. However, most liquid hardeners produce heat, increasing the risk of melting the wax (approx 1/4" thick).

We have successfully bronzed wax objects before, but have not tried hollow objects. Are there any suggestions?

Will filling it with plaster of paris and then masking the plaster off work?

Mr. Watts

It could work, however, I prefer to use a higher quality material (company philosophy). Have considered fiberglass with a DE powder for the filler, however, the heat created by the hardening compound may melt the wax unless I used a slow reacting combination. Any other options anyone can think of?

Dow (and others) make a two component RTV that generates very little heat and has several different catalysts to give long or short pot life times.

I do not think that epoxies give off as much heat as polyesters. Would be worth checking out with a Mfg.

This may not seem to be a very technical alternative, but why not just refrigerate the wax while the resin in hardening? It will certainly slow the reaction, but as long as you're not in a big hurry, the outcome should be the same.

It would be a good idea to cool the resin before mixing, so the reaction will start off slowly.

I am interested in bronzing a box of 64 crayons. Can this be done and who and where do I either send the crayons or money. It can be any box of 64 crayons I would like the top to be open on the box so that when you see it it looks like an open box of crayons.
