The tray sets we consider to be the most useful and versatile piece we make. It is a great tray for French bread with olive oil in the bowl to dip it in, a vegetable tray with ranch dressing,  shrimp and cocktail sauce or as a chip and dip. The tray is 15 inches in length and 7 in width and will go into the oven and dishwasher and even though the materials we use to create this piece are microwavable, it is probably to large too fit. Of course the glazes do not contain either lead or barium.
