A serving dish, a tray for drinks, we are using there oval trays every day in the kitchen lately.
Approximately 12.75 x 4.5 x .5"
I make these dishes by rolling and cutting slabs of porcelain, then pressing them on plaster molds I have poured. After they dry a bit, I trim the edges with a wood-working tool and sponge them smooth. I paint them with underglazes when they are bone-dry, then fire them, coat them in clear glaze and give them one last trip through the kiln.
They are safe for food, and it is fine to put them in the dishwasher.
