I've been having fun with red enamel. I've discovered that if you over fire it it can split like it has in these photos. And I love it! But, if you don't do it right, it runs all over the place, and that looks horrible. Too horrible to put on my blog spot. Just think of lots of dribbling red and you've got it. It also doesn't do a lot of good to your kiln shelves. So, if you want to give it a burl, I suggest putting your pieces on throw away bits of shelf.
