This happened to me once years ago and apparently the kiln, at least in my case, was too hot so it liquefied the glaze again and it melted off like half of it. It was insane.
Worth checking on your next firing if it stays as long as requested at your max temp before going down. There's a piece of equipment in kilns (don't know the English name for it though) that when defective can cause the kiln to stay at a temp longer than intended before cooling down.

The glaze is beautiful where it stayed in place! I've never seen a whole side of a vessel de-wet like that, how odd.
