New porcelain and glaze

Last night I opened up the glaze kiln that I fired off on Sunday. It was pretty much full of tests, so I was nervous to say the least. There was a wack of mugs in the new re formulated polar ice body. I had also tested the new Plainsman stoneware clear base glaze. I made a 1000g batch of the clear using 4% Mason Turquoise stain and then a 1500g batch of just straight clear. After all these years of putting it off, I finally got around to mixing up some of Stephen Hill's cone 6 Strontium Crystal Magic (cool version). I sprayed it on all of the mugs and dipped it on most of the rest of everything else. It is more of an enhancer than a good glaze by itself, so I sprayed and dipped a variety of our studio glazes over top of it. I knew that it would make things runny, but wondered just how runny, as the ~5% lithium carb would act to make things a bit matte. I also sprayed the plainsman clear on about 75 or so Christmas tree decorations/gift tags that I made out of the non plastic polar ice version. I am thinking of next year, as I realize that they are a bit late for 2014. Everything came out great. I think a mug kissed the spout of a teapot, so a little grinding and re firing will be required, but other than that, it was all more than I could hope for. I had visions of lakes of glaze coating my brand new kiln shelf, but no, it was all perfect. This is a picture of one of the mugs glazed in the Plainsman clear base on the inside and the bottom 1/3rd on the outside with the Crystal Magic sprayed on the top half and then a blue hare's fur glaze applied on the top 2/3rds. The second image is just a close up of the handle showing how much it can indeed run. Although you cant tell in these images, this porcelain is still very translucent, even with the darker glaze on the outside.
