Grease and griping
So this was a bit of fortuitous luck that brought this problem to my attention. I had been testing these baking pieces. I heated them in the oven to around 475 and let them cool. Then I froze them for a few hours and then popped them frozen into a 475 degree oven again. I wanted to see what kind of crazing or cracking issues might arrise. Turned out none. But I had left them sitting on top of my stove while I did some kind of frying and the insides got all greasy. A couple of days later I look and this is what I see. Grease has seeped into several of the pinholes and created this grease stain under the glaze. I think it is safe to say it is never going away, and obviously raises a huge problem. I'm a little surprised because this clay is really tight at cone 6 and I wouldn't expect it to absorb oil like this. Although, it just occurred to me, that it likely is not the clay absorbing the oil-but-you guessed it-the white slip under the glaze. Eureka. I think I just solved my riddle. But it's still a problem. I obviously need to eliminate the pinholing and crazing completely, or change the liner glaze. If I find an opaque blue similar to this one that I can apply directly to the clay without slipping that would save a step and maybe eliminate this problem. The other blue I was using-the turquoise-is not a candidate because any dribbling on the outside, even after being wiped off, resists glaze, so when I dip the outside, whereverI had wiped off the turquoise the glaze is noticably thinner. In other news, I am in the middle of another bought of insomnia. A few days now. I am very, very tired. If you fall asleep and most importantly, stay asleep every night, you don't know how lucky you are. My life really is a form of insomnia. I am lucky if I ever sleep for more than an hour or two without waking up. All night long, every night of my life. Over, and over again. I wonder if there is some kind of disability claim for this, because it really does begin to render you useless during the day after a while. I can't think straight. It's like everything I see and hear is moving through thick mud before it reaches my brain. And then it has to move through that thick mud again for me to process it and respond to it. So I get on this horrible cycle. I start drinking more caffeine to try and wake up, then I still can't sleep at night even though I am DEAD tired, and so I take a sleeping pill, which, by the way, does not keep me asleep all night. I still wake up at least three times on a sleeping pill. Okay, this is turning into a pity fest.
