The kiln at the ceramics studio has been working over time. There was a little bit of a backlog of pieces waiting to be fired. Amazingly I got several pieces back! This piece was a little bit of an experiment. First I used white stoneware clay mixed with porcelain. That is not an ideal mix for several reasons. First the 2 types of clay have different shrink rates so it is really hard to gauge how big to make something to account for the shrinkage. Secondly if the clay is not mixed well when it fires (the shrink rates being different) might cause cracking or separation. And lastly, glazes look different based on the clay body color making it a gamble on what color you will get. Speaking of glaze I experimented with layering of the glaze. Usually when I use the glaze I will hand paint all the different sections so that the glaze colors will be "true" to the test tiles. In this case I dipped the orb in Evan's Red and then applied Super T in specific sections.
As you can see the red turned out beautiful! I attribute that to the porcelain in the clay body. Red always comes out red on porcelain but more often turns a nasty brown on white stoneware. When the glaze reaches its full viscosity and mobility in the kiln, it melts fully and the oxides move about freely. During this period, the fluidity and surface tension of the glaze determines its ability to wet the surface to heal minor bare spots, and its ability to pass gaseous bubbles percolating up from the shrinking and vitrifying clay body. In essence the glaze runs and moves. This can be good or it can be bad. For this piece it was good and at the same time bad. The Super T parts melted and slid off the spots where they had been placed. I was thrilled that the red came out so vibrant and additionally disappointed that the Super T moved...
As for seeing red, I got yet another email from the ceramic studio management. They are asking for "volunteers" to clean up the studio. You won't get a price break on the cost of the classes, nor any perks, just a warm glow knowing you are helping fellow students. Call me silly but I'm shelling out $152 for 8 classes and they have hired 3 people to handle the studio and they are trying to guilt, arm twist, and force me into doing their jobs! If I clean up the studio once a week I want to get paid for it - either with a class credit or cash money!
