The wax carves quick and smooth.

Anyone else sculpting in wax?

I'm not carving wax right now but I've wondered about it for a while and hope that you can answer a few questions for me about your process--

Can you tell me more about how you use the wax? Is it for mold making? I saw this blog post a while back( http://linda-ellett.blogspot.com/2011/02/frog-1carved-and-really-for-casting.html ), where the tile artist shows her models but doesn't go into how she casts them. I'm assuming with plaster? How does carving wax for use in molds compare with using clay? Thanks for any help in clearing up the confusion, I do have an interest in carving wax when my sculpting skills are a bit more accurate.

I have been looking into this also.  I had tried just paraffin but the result were not usable.  I am not familiar with all of the ingredients.  Does this wax degrade over time?  Can you recycle it?  I want to make sprig molds.

 

Thanks for the info.

I'm far from being an expert, but here is an overall outline of the process.

 

 

You make the first sculpture from clay because wax is very hard to get the rough shape, and the wax would be expensive to grind away into waste.

 

I use Roma Plastilina clay for the peliminary sculpture, and plaster molds. If you mold with RTV silicon you would want a sculpting clay without sulfur.

 

The peliminary sculpture is sculpted as good as you can get with clay. Then you make the molds from the sculpture of plaster or what ever you prefer. I use plaster because I belive in using the cheapest material that gets the job done. Soak the clean plaster mold in water overnight or until saturated. Heat your wax pour it into the mould wait for the wax to get about .25" thick then pour out the remaing wax, when it's cool remove it from the mold and start sculpting.

 

The benifits to the wax are:

Greater detail than clay

You can add to the wax or weld pieces on with a wax pen or a alcohol burner with some stainless steel dentist tools.

You can machine the casting wax.

You can sand it, and buff it to a high shine.

The wax is reusable

If your makinging a doll you can string it up test the prototype for fit.

You could use the wax sculpture as a master for the final mold.

 

You can use this wax over and over. If you were to use plastic in the wax like a home made wax a machinest would use you would limit the life of the wax.

P.S.

If you use Talc from a ceramics supplier, the talc may be as black as a Model T Ford when mixed with wax.

Make sure the talc is white, black or translucent material is harder to sculpt.

Adding some titanium white powder or some crayons may help make the mix more opaque.
