06 Waste Molds Nº 31




This is the oil-clay leg in the build-up, with the shellacked coddles clamped around it securely, ready for the first half of the hot-melt moulage mold to be poured. Click on any image to enlarge it.






I melted six jars of chopped-up moulage for each half of this mold. This photo shows the stirring spatula in the stainless steel container with the melted moulage. I stir and wait for the temperature of the moulage to reach a pourable temperature.






Here is the first half of the mold poured.






I covered the first half of the mold with plastic and waited for it to completely cool down.






Once the moulage was cool to the touch, I removed the coddles and the build-up. I have also removed the clay that was around the wire at the ankle. This should create a key. The wire will go through the mold, but since the mold will be sitting on the table, with the wire hole down, the wax should not leak. I have added some clay to this side of the spare.

Here I have replaced the coddles around the first half of the mold.






I melted and poured the second half of the mold.






I opened the mold and removed the oil-clay leg. Guess what? I forgot to carve some more registration keys in the first half of the mold before I poured the second half. The only registration key I have is at the ankle. The only thing I can do at this point (besides doing it over again) is to try and align the walls of the mold so there are not any offsets.



I have cut four pieces of cereal box cardboard, and folded each piece in half, to use as a mold box for pouring carving wax into the mold. The cardboard overlaps, and is held together with masking tape. I ran out of time to finish the carving wax pour, so I just wrapped the mold up in plastic until I can melt and pour the carving wax tomorrow.
