This ancient cast iron tetsubin is not glazed inside, so that the water can interact with the iron. Iron adds a nice sweet and deep taste to the tea. Therefore, it's more suitable if you brew Oolongs or puerh. This tetsubin has signs of rust inside and water residue (Calcium), but the water coming out of it is transparent and good to use. However, it still has some old smell because it hasn't been used for a long time. This will improve as you use it often.
The best way to take care of a tetsubin is to use it very regularly. Each time, it's important to empty and dry the kettle when you're done using it. If you leave water in it overnight, the iron will start to rust and this will produce a heavier taste for the water. Don't use chemicals to clean it. Only a clean, dry cloth for the outside.
This tetsubin shows signs of good craftsmanship. The iron is of good quality and the sound of the metal is high pitched like a bell. The handle is nicely bent, which improves the way you can hold it in your hand. On top, there are some wabi sabi imperfections: it looks as if pieces had been bitten off. This kettle is best used for a very slow water flow that maximizes the aftertaste of the tea. It can be heated on an induction plate.
