I agree with ICE. The teaware museum in HK Park should be much reliable.
BTW, regarding to my previous comment on department stores run by Chinese operators in HK. This comment may have confused those who are not living in HK. There are many good department stores in HK, and most are run by local businessmen. However, the two stores I mentioned are operated by ppl come from Mainland China.
I agree with M. I think boiling water can kill the mould. Never use detergent to clean your pot.
To Sofie. It’s a big question. What I am petty sure is that you should never go to those two department stores run by Chinese operators (“Chung X” and “Yue X”).
