I'm not aware of how to do quotes in quotes. Too tricky for me apparently. So @ Jay, happy to hear you were able to identify what is going on with the Fang. A quick search on TC turned this thread up, although it's quite dated: http://www.teachat.com/viewtopic.php?f=36&t=5821. Perhaps ask around and proceed with caution before doing anything too drastic. You could even go with heavydoom's suggestion to "...leave the calcium on the pot, if it does not hinder your pouring out of tea, it adds character to your pot. kinda like a beaten up old leather bag."

And @ Victoria, I did end up drinking the AOI this afternoon after reading your comment. It was quite good and got me through the day, even with no coffee, surprisingly. But I must admit, I do like a cup of black bitter in the AM, at the very least. I know, sounds appetizing.
I'm probably the only person who pulls items as he's selling them. But I've come full circle and have decided to relist the following two Yixing:
1. 40ml early 80's Factory 2 HeiNi Shui Ping (see picture below and page 1 for additional pics) - brand new, never used
$115 (purchased for $156, so $41 in savings) ~~~~~Sold!~~~~~
ShuangXi Cup from Late Qing / Early ROC period FREE with pot
2. 1987-1993 50ml Factory 1 Zini Fang teapot - (seepage 1 for pics) - also brand new, never used, actually still in original wrapper
$115 (original purchase price, but based on J's feedback I think it's worth original price paid) ~~~~~Sold!~~~~~
International 2-day shipping included in price of pots
EoT's 2000 Camphor Aroma Sheng Puerh and previously available 2013 Half-handmade ShuiXian Wuyi Yancha samples included with both pots
Note, the flat Gisui kyusu and Sakura caddy on previous page still up for sale. And last, let me know if you have any questions on the items. Have a good one.
