Technicians on porcelain and food have jointly conducted experiments in three months' time on the practical value of purple-clay teapots. They have used TC-PIIG automatic color identification technique and chromatism detection technique. This experiment ranges from Yixing purple-clay teapots, Yixing cinnabar teapots, and white porcelain teapots and glass cups. They used these containers to brew green tea, brown tea and oolong tea and analyze the color, aroma, taste, residue of the tea, tea polyphenols, caffeine, reduced sugar, theanine, tea cream, etc. The result is, the former two kinds of purple-clay teapots in better than other porcelain teapots and glass cup.
