Many asian coutries sent their peoples to the West, to open a stage of technologies, like old day's Japan, 80's China or HK under international influence. There's nothing more evident to visit and see themselves (there are exceptions like Ruth Benedict)..I think Yixing teapot is similar..I mean it's not easy to know it after graduating internet university
Learning a culture is never an easy thing, it's not all the Chinese understand Yixing teapots either..it's better they don't cos the clay already got depleted and Korean Yixing market is somewhat stagnant after having 20 years of Korea-China relations. If learning that is easy, the Koreans would be so easy to launch business in China and make profits but they always face difficulties in localization.
I will cut the crap..There are 3 points in buying Yixing teapot IMHO.
1. Antique or vintage Yixings..this one you need trustful sources..older experts in Taiwan or mainland or go to auction but this can cause $$
2. Master Yixings...good Yixing potters (like Shipiao for Li Han-yong, thin-wall Yixings for Chen Guo-liang or Zhuni for Xu Jin-gen) are already well-known so this one needs more $$ than vintage Yixings because rich main-landers are after it.
3. Quality Yixings by relatively unknown artists, a niche market or Factory-1. I find this market to be idle for west, and most economic. But this market is also not so abstract as it seems like many potters use the same moulds over. If I talk more, it's like I am talking something I don't know..so
