Argh. I've been preparing for a large-scale redecoration, and when I was putting some stuff up in the attic I noticed that a really nice turn of the century milk jug I had stored on a shelf up there had decided to split, quite violently, into three scattered pieces. The attic isn't prone to extreme changes in heat or humidity as it's well insulated and ventilated, so it's a bit of a :huh: situation. I've got many large cased pieces up there that you would have thought would disagree with any changes before a plain clear jug.
Ho-hum.
