Crawling. That is what happens when too much glaze is applied on my trim tile pieces and the glaze pulls itself off of the clay piece, I am told. And it's particularly bad with the exact glaze I am using - Downright White. It happened to about half of the pieces that I had glaze fired last week.
My next step is to retouch the pieces that this happened to, take them to get refired and hope for the best. Otherwise, I may be starting all over. This trim tile part of the dining room project has really been a hassle and progress for this is, should I say......"crawling". Here are the pieces that did make it out successfully and I'm pleased with.
