New to me Lin's Ceramics teapot (got from Tea Swap here - thanks Jeremy). It is hard to really quantify any changes the clay makes, however, my first pot of tea did taste differently than the same tea from either gaiwan or other teapots I had been drinking it out of for over a year. Slightly sweeter and more of a black tea flavor, from the 1990's pu'erh I christened it with. Since the tea water spends only a few seconds in the pot, I am not sure how the affect works, but the pot does seem to change the flavor profile. Over time, with more teas tried, I will get a better idea on changes the pot brings. Perhaps next I will try an oolong.
Here it is with a moderately chipped ming tea bowl - I wanted to start with a bit of a special cup for it's inaugural brew.
