How to season a Chinese clay teapot

„Touch:
You, the person brewing the tea is entitled to touch the tea leaves with (clean) hands. What does this contact tell you about the tea? (For me, a 'heavy', compact leave is a sign for a good quality tea.)
Then there is the pleasure of touching the porcelain and to feel it in your mouth. Do you notice how a cup with a different shape will change the taste and pleasure of the tea? And can you find which cup is best for your tea (I tend to prefer old and thin cups).“
