I have a lovely teacup made by a local artist that I managed to drop on a stone floor about 2 minutes after purchasing it. It survived pretty well, considering. There is a 1/2"-1" diameter chip missing out of the lip of the cup, and aside from that it's intact.
So! How do I make the best of this teacup, assuming I want to keep it?(which I do!) The missing chip is a little jagged, and I'd love to sand/smooth it down somehow, and if possible, seal it in some manner, without making it unusable as a tea receptacle that will be near my mouth and such. It's made of high-fire porcelain and glazed, as it were, with low-fire colored clays. I've crazy-glued the larger chips back in place.
You can see some pictures here.
