Chōsen Karatsu Wood-Fired Guinomi by Mike Martino

A hand-pinched guinomi by Karatsu-based ceramic artist Mike Martino.

We met Mike at his pottery studio in Karatsu, Japan, where we personally selected these pieces for After Tea. His work draws from the region’s centuries-old pottery traditions and celebrates the natural character created by clay, ash, glaze, and flame.

Each generously sized guinomi is formed by pinching a ball of clay by hand rather than throwing it on a pottery wheel. This process leaves subtle impressions from the maker’s hands and gives every cup its own organic shape.

The cups are glazed in the Chōsen Karatsu style using two ash glazes applied in slightly overlapping layers. During firing, the glazes flow down the surface and react with the clay, creating natural variations in color, texture, and movement.

Each piece was wood-fired for approximately 55 hours, reaching a temperature of about 1320°C (2408°F). The extended firing allows flame and wood ash to leave distinctive marks across the surface, making every cup unique.

Traditionally used for sake, this larger guinomi is also a beautiful vessel for tea, espresso, bourbon, or anything enjoyed slowly.
