New things, and glaze issues

Here's some crappy cell phone pics. Real, honest to god pics to come. Honest.

I'm pretty pleased with my test tile birds. I may continue to use bird forms for testing glazes. They're quick and easy to make, have nice texture from the serrated rib, and now I have extra quick sell things for upcoming art fairs.

(Ceramic tech geek stuff to follow. If you're not a ceramicist, this is the boring part. You can skip it.)

All the pink glazed stuff got messed up. The glaze crawled like crazy on the inside. I wonder why that keeps happening? I applied the glazes all the same way, pouring them on the inside of the cup, and brushing the outside. The blue and aqua glazes are fine, but the pink keeps crawling. I'm thinking I either need to thin the glaze, or just brush on the interior from now on. I also read that tin and zinc oxide in a glaze can make it more likely to crawl. I wonder whether the Amaco Pink has either in it? Don't both act as opacifiers and whiteners? I'm guessing they needed some sort of white to make that particular pink shade. (Just looked up glaze colorants, and tin oxide is used in chrome tin pink stains. Aha!)

Does anyone know whether there's anyway to fix a glaze that's crawled? I'm debating whether to sell them as seconds, or to put a layer of clear on and refire them, in the hopes that the glaze with settle down. Any advice would be appreciated.
