I throw this porcelain dish on the wheel then slightly alter it when I first remove it. It is glazed with a cobalt splash with a durable glossy clear glaze overall. I then fire the dish to 2350º F in a reducing atmosphere. It measures 5" wide by 1 1/4" high. I use grolleg porcelain which is imported from England, it is whiter and more translucent then domestic porcelains.
