A Week With Li-Qua-Che 2.0

This post continues with our week long experiments with Li-Qua-Che. The photo above shows design model #2. The cork sub-straight has been gessoed and oil clay has been added to smooth out and build up the surface.

This is the plaster mold pulled from the above model. It has cured in the oven over night. The mold measures about 12" square.

And here is the finished Li-Qua-Che casting. The Li-Qua-Che picks up every detail including scratches and finger prints. So make you model as smooth as possible, and then smooth the walls of the plaster mold as well.

There was some difficulty getting the casting out of the mold, but with the help of a small pallet knife, it finally came free. The real issue was that while the casting was sitting on the table curing, it began to sag and warp.

Summing up our experiments so far, this material is surprisingly strong, but it has size limitations. It will not hold its shape if casting a single sided tile over 10" in size. With that in mind we'll move onto designing two more projects; a smaller 8" tile, and an object that is similar in proportion to a doll head.

Here's a link to some more Li-Qua-Che tips at Konittajo's Playhouse.
