Bugger. My wife dropped a dinner plate yesterday, whilst emptying the dishwasher. We only have had 4 of that size to start with. It's Denby, but carries no marks, and is a plain grey-brown. The last time one was broken was over 25 years ago, and that ones replacement was a patterened rather than plain one. I fear we'll struggle to find a replacement to match either the patterned or plain, especaily as we have no idea what the designs are called.
Same problem, our wedding china is a Denby blue, about three years later it was discontinued. Some of the remainders are safely chipped and we bought a bunch of plain white backups a couple of years ago
My (first) wedding china was Denby Romance. Whilst we were engaged, we went and chose it, and the nice lady said "Oh, that pattern will be in production for 20 years at least". Er, it was discontinued before we were even married! We had to spend all our wedding present money on buying stuff to complete the set, including spending half our honeymoon trawling shops who had stock left. I suppose that was an indicator for the marriage, which lasted about 8 years.
We (the 2nd Mrs W, with 27 years endurance award) are still using that china on a daily basis, although we did buy a set of plain white stuff when we moved house. Obviously it wasn't Denby, as I wouldn't trust them again!
