I unloaded the soda kiln today to get out these glaze tests I did to help correct the crazing. I kept the color variable the same in the test so at least I can see that is consistent. I'm happy with the color, only the things I tried to decrease the crazing (cracks in the surface) didn't really show up because the soda we put into the kiln worked against me! It creates even MORE crazing. So I can't win! Every single tile looks pretty much identical, so I can't even detect which portion that I altered in each test worked or not. I'll at least try some more in my next large kiln load that I fire, which will be a couple months. This so called crazing problem might not even be a problem when it's a liner inside a bowl in an area where not as much soda comes into the kiln. So we'll see....on with the testing, right?
