The form originates from medieval Europe and is typically used for soups, stews and similar dishes. I find porringers very comforting to eat from as your hand can wrap around the form.
Originally I was trying to find something to shield the jugs on the top shelves of the kiln as the glaze finish I was previously using didn’t work well with the flames and higher amount of ash & soda in this area of the kiln. Not to waste space in the kiln I started making the Porringers, with a slightly thicker rim it allowed me stack them rim to rim then foot to foot as high as I needed to go. Wadding, a mixture of Alumina and China clay, is placed around the rims and the foots so during firing they don’t stick together.
