A 600 ml heat-resistant glass teapot with a removable stainless steel infuser: the leaves brew loose, and lifting the basket out stops the brewing before it turns bitter. Dishwasher and microwave safe.

A 650 ml pot with a stainless steel infuser — low at 9 cm, so it fits on a tray or in a drawer under the worktop. Two or three cups per brew. Thermostatic glass, dishwasher safe.

The smallest pot with an infuser — 600 ml, just 6.5 cm across and 16 cm long. A one-person size: two cups, with nothing left to go cold. Thermal glass, dishwasher safe.

A 950 ml teapot with a bamboo lid — four cups, the size for everyday brewing for two with a refill. The glass takes a flame, so the water boils in the same vessel. Dishwasher safe.

A 1600 ml teapot with a bamboo lid — clear, untinted glass, so you can watch the colour of the brew and catch the moment the tea is ready. The water can be boiled straight on the hob.
