The weight of a good cup

Pick up the cup you use most mornings and weigh it in your hand. The mugs that accumulate in kitchens — promotional, novelty, orphaned from sets — are almost all too light, too thin at the base, too wide at the mouth. The cup we reach for first is hand-glazed stoneware, thick-walled, with a base heavy enough that it sits down onto the table with a small decisive sound. It holds two hundred and fifty millilitres. It has survived six years of daily use and two removals.

The weight is not an affectation; it does things. Thick stoneware walls hold heat, so the coffee stays warm to the last third instead of the last sip. A heavy base sits stable on desks and sofa arms, forgiving the small knocks that send lighter cups over. And the glaze — dipped by hand, pooling darker where it ran — makes each cup singular in a way a printed pattern never is. The irregularity is not a flaw tolerated. It is most of what you are buying.

A good stoneware cup from a working potter costs €25 to €40, which sounds extravagant against a €6 mug until you divide by mornings. Choose it in person if you can: the handle should take three fingers without pinching, the lip should be thin enough to drink from cleanly even where the walls are thick. Then let it become the cup. Rituals attach to objects, and a first coffee deserves better than whatever the cupboard had going spare.
