Why we fire to cone 6
Lower than porcelain, higher than earthenware. The temperature that lets a mug survive a dishwasher and still show the clay.
Every potter picks a temperature and lives with it. Ours is cone 6, about 1240 °C, and it was chosen for the kitchen rather than the gallery.
At that heat the stoneware body vitrifies: it stops absorbing water, so a mug will not pick up coffee stains or crack in the dishwasher. Go much hotter and the glazes we like start to run; go cooler and the body stays porous.
What it costs
A cone 6 firing takes about nine hours up and a day and a half to cool. We fire once a fortnight, which is why a sold-out piece can take a month to return.
