In short the direction the seal is facing does not mean anything at all, right? I just took a look, I think half of my pots faced one way and the other faced another.
I am still raw and have alot to learn....I have a question on age of the pots. From what I heard from other more experienced people, the teapot could be ID more or less to the decade by 1)the clay 2)how it was manufactured 3)the shape/style of the pot. How much of that is true?
Yes you are right with those pointers but it is just a ripple in the ocean. I know a few old and professional teapot dealers and they are constantly at disagreement with the facts of the pots they found. At their expert level they are still doubtful. These people are really knowledgable and can point out the fakes in auction houses and museum instantly and they still have doubt often.
Even for me after decades, I am still on the learning curve and paid my tuition fees for mistakes. In the end, I will only buy if I am very sure and familiar with the pots. I also hunt very often for pots in collectors home and some of them really accumulated heaps of rubbish pots. So, tread cautiously in this path.
If you ask me, I would say a better and sensible approach is to pay moderately for Japanese, Korean or new age pots like those done by Peter. In terms of value, artistic, artistic expression, functionality and definitely cost, they are wiser approach and so much better.
Yixing pots, unless you are sure and have access to historically abundance place like HK Taiwan Thailand Singapore and Malaysia, then your chance is better. But it is getting rarer in those places now. I hunt for them very actively and frequently in these countries, still the excitement always mix with fear.
So my friend, please go slow and tread cautiously. Start with a nice Gaiwan first.
