As well as being an incredible ceramic artist, Jeff also publishes this awesome little bike culture magazine called Urban Velo. See it on the web here.
The beautiful wheel-thrown stoneware “chawan” or “tea bowl” was fired in a gas kiln to 2200°F. During the firing, soda-ash was introduced, creating a natural glaze on the raw clay surface of the bowl. The inside features a smooth, glassy glaze: a Tessha, or iron red glaze, a traditional Japanese favorite.
The marbled effect is achieved by wedging porcelain into the stoneware (very difficult to do well).
This teacup is THE perfect size! I look forward to spending lots of time with it, and perhaps in the future will expand my budding Guerrero collection. 🙂
