Have you tried CARVEX or FILO wax?? My wife uses this highly
plasticized and hard wax for all of her jewelry and figurine carving.
It is very hard, easily machined to near knife sharp edges. Most
jewelry suppliers should have it or Kindt Collins makes it. One
problem is it can be difficult to cast as it melts at about 360F and
there is a tendency to crack the investment. (If we cast it, we
invest it, pre heat the kiln to 500-600F and put the investment in
after it sets for 2 hours, using R&R Dentsuply (spelling)). Normally,
we make an RTV mold of the master, shoot waxes and cast the shot
waxes, never casting the master.
I think you will find this wax will allow you to get GREAT, clean,
crisp detail. Cynthia carved a 2.5 inch tall Christmas Tree that has
around 115 ornaments/items on it. Biggest problem for me is seeing
the detail. She carves using 3X glasses and a 4X Optivisor.
Good luck, hope this helps.
