When I initially started experimenting with wax around 2009-10, it was pretty difficult to find anything on the actual process that was used in creating anatomical models and wax relief portraiture in the 17th century. The only references I could find, that were not in Italian, were contained in the really fascinating articles Joanna Ebenstein was putting out on her website Morbid Anatomy based on her research and travels, and a few references in books written on Anna Maria Grosholtz's (Madame Tussaud) work prior to and during the French revolution for her "Salon de Cire" in Paris. I took little bits of information here and there, wherever I could find them, continually experimented and eventually started to rely upon a process based on trial and error.. I probably lost 75% of the pieces I attempted until about 2012, but there's really nothing that compares to working with wax if you're a sculptor, and beeswax in particular. It has a beautiful warm translucence after it's polished that you just won't find in any other sculptural medium. So while it was frustrating, even the small successes were quite motivating.
I usually start any sculpture with a clay body. After I've roughed out a form, I create a plaster mold from that and then cast the sculpture in beeswax. After I pull the piece from the plaster mold, I carve in the details with fine carving tools, polish, paint it in oils or wax based pigments that I create by hand, sometimes I add gold leaf , wax dipped laces or velvets.
I like to compile little time lapse videos of the process from start to finish. Be sure to un-mute each video for musical accompaniment!
