A couple of more models came out of the kiln this morning, the own center and the Nortown Theater Art Deco panel Nr D7.<\/p>\n

D7 weighs 38# and it was somewhat of a surprise that the panel weighs pretty much what it weighed before going into the kiln, I had thought the process would continue to burn out materials, the chemically combined water, and that a percentage of the weight would be lost as a result, that seems not to be the case though it may have lost a very small amount of weight the scale wasn’t accurate enough to register, on the order of less than a pound.<\/p>\n

That was good to find out as I now know the final weight for the fired ware will be very close to what the sculptures weighed when bone dry before being fired.<\/p>\n

Shrinkage however is another story, as expected, the firing process results in about a 1\/2″ shrinkage per lineal foot, so the D7 panel is around an inch shorter in length than it was.<\/p>\n

Of course this is a known factor and compensated for in overscaling models if a certain size is required in order to fit it something else.<\/p>\n

One could in fact achieve a size reduction in this way by repeating the process, I could take this fired model now, make a plaster mold from it, press clay into the plaster mold and fire that cast and make a silicone mold. The resulting cast-stone casts from that would be consierably reduced in size, but the amount of work involved would be more than simply making a new smaller model.<\/p>\n
