I was brewing tea when this happened. It was late in the evening and when I was adding boiling water to the teapot, I heard a soft bubbly sound......like a sound of a fizzy soft drink when you opened a can of soda. Initially, I tried to look for the source of this fizzy sound and realised that it was from the teapot.
Old timer Chinese tea drinkers who used clay teapots to brew their tea, have told me about this fizzy sound phenomena. This would most probably be caused by a very tiny hairline crack in the clay. It is not obvious, in the sense that when I examined the teapot in detail after washing the teapot, I was unable to detect any thing (visually) or any crack on the teapot. I was told that after prolonged use of the teapot, it will eventually start to leak tea.
I am still happily using this teapot. This teapot looked elegant and is thick walled. Good news though, I had bought 2 of these teapots long ago. I do not buy doubles.....maybe I am lucky. Teapots usually meet its demise not through regular use, but in my opinion, more through accidents. Dropping the teapot or lid during washing, or dropping something heavy on the teapots are common accidents to teapots.
To this particular teapot, thank you for the memories.
