Pricing a mug without apologising

Pricing. Most potters undercharge, and I did for years. Write down the clay, the glaze, the firing, and then your hours, honestly, including the ones that went wrong. Your hour is a real cost. When someone asks why a mug isn't cheaper, I say, because it was made slowly, by hand, to be used every day for 20 years. Then I stop talking. You're one thing to try. Cost one piece properly this week, every minute included.
