Query: disappointment

While I still Love the pattern and the color was just what I'd hoped, I received two sets of these dishes and both had air bubbles in the glaze on the plates - showing bare stone in tiny circles all over the eating surface. While Amazon was good to exchange and then return them and provide a refund, I am unfortunately out a large promotional gift certificate and very disappointed with my experience with these plates.
