well, I'd use them!
I am also a potter(though haven't been able to do clay much with having to raise my child for 17 years alone until my recent marriage) Anyway, yes, you can buy a set of dishes for 10 bucks at WalMart or puchase a hand-thrown plate by an artist for 40 bucks+. If I had the money, I would help out fellow artisans. Kinda like the person here who was upset that she was asked by a relative to knit something for cheap. Art/craft takes talent and time, and I think it's worth the money (even though at this time of my life, and probably forever, I don't have the money to purchase things that way).
At the same time, I'm big with recycling. So perhaps I'm just confuse-d.
