A square shape, unusual for a teapot, but for good reason: the wide base allows the leaves to spread out instead of piling up, which improves the infusion.

Borosilicate glass withstands temperature changes and retains no flavor — you can switch from a smoked tea to a white tea with no aftertaste. Removable stainless steel filter, two sizes: 35 cl for two cups, 75 cl for the whole table.

And the glass shows what cast iron hides: the leaves unfurling, the color rising. With a white tea or a rolled oolong, it’s quite a spectacle.
