Have you ever think about why there is that dark dirt inside your pot, after you "Clean" it and its still there? Those are oil residual if I am seeing it correctly, and I could be wrong. But if your Tao practicing, Old Clay Qi sensing and Chemical Pot Smashing tells it is alright, then good luck.
We are all trying to help each other here, specially in the yixing selection. There are so many ill-information flowing around, and your "finger to the moon" idea of not even looking at what you have in your hand is certainly not pointing to the right direction to help others. Not long ago, you learnt that there are differences between wheel thrown pot and a yixing pot. Some of the members here did helped you to identify what you had in your hand was not what you think it was. viewtopic.php?f=36&t=11539&hilit=hand+thrown&start=1395#p233148
I am not trying to discourage you in anyway. I think you have a very light hearted way of dealing with things you dont know or want to know, and thats a good thing. But please be more patience and test it out, look more, read real books about the subject, feel more or perhaps the old tea person with the aged DHP could help you look into the moon more clearly?
btw. Try boiling that long leg pot from cold water for an hour. Cool the water and you will find a layer of oil on the surface and white waxy stuff sticking on the side of the boiler, clean out and repeat the process again until the boiling water is clean. I would also recommend bleaching the pot after the 2 boiling. That should get rid of the dark thing in your pot. Also, the darken discoloration of the end of the lid leg.viewtopic.php?f=36&t=16159&p=207679&hilit=+chemical+pot#p207679
