A tetsubin quietly used in everyday tea moments
Kobaguchi is a cast iron kettle made for boiling water in daily use.
It is characterized by an extremely simple form, stripped of ornamentation to the bare minimum. Rather than asserting a strong presence, this tetsubin is designed to blend naturally into everyday tea time, fulfilling its role quietly and without excess.
A concise form where shape itself becomes the expression
The body is compact and gently rounded, offering a sense of stability.
With no decorative elements, its impression is defined solely by outline and overall balance. The spout is short and set at a natural angle, while the handle forms a clean, restrained arc that allows pouring motions to settle effortlessly. Both visually and physically, the kettle imposes no strain, integrating smoothly into daily gestures.
Process considerations demanded by simplicity
By design, this piece results in a casting mold that is particularly fragile.
As a result, exceptional care is required during removal after casting. The mold is released gently, without applying force, to preserve the integrity of the form. Beneath the finished appearance lies a quiet accumulation of handwork, sustaining the simplicity that defines Kobaguchi.
Recommended For
- Those who wish to use a tetsubin in everyday life
- Those who prefer tools free of decoration
- Those who value the handcraft that supports simple forms
