I have just done the washing up and noticed that one of the saucepan lid knobs seemed a bit loose. So I tried to tighten it but went the wrong way and the whole knob came off in a dismantlable way, knob then big washer thing and screw and metal disc and underneath it was... well the lid is glass and there was a circle in the middle that was looked like a weasel had spunked on it and then rubbed peas in it [boak]
There are three saucepans in the set, the other two were the same, I am horrified and disgusted with my slovenly saucepan lid habits.
