The tray sets, I consider, to be the most useful and versatile piece we make. It can be used as a chip and dip, a bread plate with olive oil, cheese and crackers, shrimp and cocktail sauce, vegetables and ranch dressing, plus a multitude of other uses. Anytime we have people over or attend a pot luck, this piece is out and in use. The trays are about 15 inches long and 7 in width, the matching bowl is about 5 1/4 square. The glazes do not contain either lead or barium and can go in the oven and dishwasher.
