Manmaru (Round Shape) Pot

Glass Teapot — Handcrafted by Craft You, Niigata

A Pot Designed Around the Leaf
A glass pot with a round, generous form. The golden brass handle rises in a clean arch above the body, complementing the transparency of the glass. The result is an object that earns a place on the counter rather than in a cupboard — something you want to keep where you can see it.

Heat-Resistant Glass — The Same Material as Laboratory Beakers
The body and lid are made from heat-resistant borosilicate glass — the same material used in laboratory beakers and flasks. It withstands sharp temperature changes without cracking, resists odor absorption, and does not discolor over time. The transparency is a practical feature as much as an aesthetic one: you can watch what is happening inside.

The Jump — Why the Shape Matters
When boiling water meets tea leaves in a well-shaped pot, the leaves begin to move — rising and falling through the water in a motion called "jumping." This circulation draws out the full aroma and flavor of the leaves. The round form of this pot is designed specifically to maximize the convection space, giving the water and leaves room to move. The wider the convection, the more fully the leaves open, and the better the brew.

Made One at a Time by Tokuma-san in Niigata
Each pot is made by Mr. Tokuma at Craft You, a glass workshop in Niigata Prefecture. He melts, molds, and processes every pot individually using a burner flame. The brass handle was chosen after testing stainless steel and copper — brass was selected for the way it changes tone with use, developing its own character over time. The handle is fixed at an angle that forms a clean arch upward without tilting, and the lid is designed so it does not fall when pouring.
