What Is Living Glaze?

People ask me what living glaze means. It's easier to show than to say. It's the surface of a cup that keeps changing long after it leaves the kiln.

A Jianzhan glaze isn't sprayed on like paint. I grind stone myself and mix it with a little wood ash from the fire. I brush that slip onto a cup I threw by hand. Then the cup goes into the kiln and everything that happens next is out of my hands.

The fire does the painting

At around 1,300 degrees, the minerals in the stone melt and run. Some of them pool into streaks. Some break into the little silver dots people call oil spots. Some form the thin lines you see in hare's fur. The same glaze, the same kiln, a slightly different spot — and you get a different surface every time.

That's why I can't promise you a colour. I can promise you it won't be repeated.

Why it's called living

A factory glaze is finished the second it cools. A Jianzhan glaze isn't. When you hold the cup, pour tea into it, let it sit, the surface keeps talking. Tea stains find the little cracks. The oils from your hand settle into the matte areas. Over months, the glaze looks deeper — not worn, more awake. That's the living part.

The same is true when we set a fragment of that glaze into silver. The ring carries a piece of a firing that can't be reproduced. You're not buying a finish off a rack. You're buying the one that survived.

How to care for a living glaze

Treat it like a thing that's alive, because it is. Rinse it after use and dry it with a soft cloth. Don't scrub it, don't put it in a dishwasher. If it's a ring, take it off before you lift weights or garden. The metal is tough; the glaze is old and patient.

Leave the tea marks. That's not dirt, that's the record.

I don't make many, and I don't hurry. When you hold a Luminya piece, you're holding a day when the fire was kind — and a surface that isn't done changing yet.

That's the honest version. The rest is up to the kiln.
