The Method For Resin

As far as I know, Martha's Method can be adapted to making resin BJDs as well as porcelain BJDs. Here is the method for making a resin BJD, in a nutshell:

Martha's Method for Resin BJDs
01. Concept drawings & full size working drawing of BJD
02. Wire armature & modeling stand
03. Oil-clay original sculpt
04. Remove from modeling stand
05. Cut limbs and head from torso
06. Make intermediate molds for casting carving wax
07. Cast carving wax doll parts
08. Cut carving wax doll parts at joints
09. Cast carving wax balls for joints
10. Weld carving wax balls to carving wax doll parts
11. Make sockets in doll parts to fit the ball joints
12. Test string the carving wax BJD
13. Refine the tested doll parts to the final finish for molding
14. Make silicone rubber molds of the carving wax doll parts
15. Cast resin into the silicone rubber molds
16. De-mold and finish all doll parts
17. Insert eyes and attach eyelashes
18. Assemble the doll with elastic or spring tensioning
19. Faceup doll and body blushing
20. Make wig, clothing, shoes and accessories
21. Photograph and display finished resin BJD.

The first 13 steps are the same whether I'm making a porcelain BJD, or a resin BJD. The original sculpt is modeled in an easy to manipulate material, such as oil-clay. Oil-clay is reusable. The only thing that is not reusable is the wire armature, and that is because the doll is cut into parts, destroying the wire armature. If hot-pour moulage is used to make the molds for casting carving wax, then it can be reused as well. Finally, the carving wax itself can be reused.

So it is quite possible that I can use the same carving wax doll parts to make a cast resin BJD, after I have made the slip casting molds for Aalish. I could use them to make silicone rubber molds for casting resin. They may need a little bit of clean-up, but that will not be very much work, compared to starting and finishing a doll from scratch.

I will consider this as an option if Aalish turns out well in doll composition slip. It would require purchasing a pressure pot, though, and I'm not sure if I want to. I already have an air compressor in my studio.
