One-Cup Teapots
Five small pots, each holding roughly one to two cups. They exist because a novelty teapot spends most of its life on a shelf and only some of it on a table, and a small one earns its space more easily.
The three range cookers come from the same mould, so a pair or a row of three lines up exactly. The tap is the smallest thing we make at about 6 fl oz — one mug, and no arguing.
