This pot is perfect for one. It doesn't have a basket, meaning the rolled whole leaves have more space to absorb more water - which in turn makes for a better tasting pot of tea. Also, because it's made of borosilicate glass it's tough, and you can see exactly what's going on inside.
This pot is dishwasher safe. But don't forget to empty the leaves first. Don't stir, especially when it's hot. Never use if you notice any cracks and the lid should fit snuggly.
