Please note that if you use harder water than 200 miligrams/liter, your tea will come out bitter, hard water makes Japanese tea bitter and undrinkable, use brita filter or you will ruin your tea, or buy some soft water and try it.
One other thing, tetsubin + Banko purple clay or Tokoname clay all have magic properties of reducing bitterness, I only have a banko, but I need to use more leaf with it than compared to porcelain, because it greatly reduces bitterness, makes tea smooth, great quality sencha is strong, that is a good thing, it has a lot of "tea material" in the leafes, you need to brew it right to experience the magic, so buy bottled soft water, use a little bit less leaf and less temperature, do not use yuzamashi (minimize heat loss of the tea), only cups and kyusu pour alteratively, calculate the pouring time in and start pouring at 50 seconds.
Hojotea wrote that the effect of the reduced iron tetsubin is far greater than the effect of banko, so I am really tempted to buy, I am satisfied with clay kyusu, I cannot imagine what my tea would taste like if I brew it with the right equipment and water.
