Generally, a more exquisite certificate will not only cover the bottom chapter of the pot, but also cover the bottom chapter and the inner chapter together. However, it is difficult to use the same seal for the certificate seal and the pot bottom seal.
Generally, a more exquisite certificate will not only cover the bottom chapter of the pot, but also cover the bottom chapter and the inner chapter together. However, it is difficult to use the same seal for the certificate seal and the pot bottom seal.
The same seal, which covers both the certificate and the bottom of the pot, is such a trivial matter that it takes great effort to clean it up twice. This is not very troublesome.
Therefore, in order to simplify, many artists usually prepare multiple seals, one seal and one seal certificate. This is also the reason why many pot makers' certificate seals are inconsistent with the pot bottom seals.
Even if the pot maker cleans the inkpad of the pot and then covers it with a certificate as mentioned above, when the pot is ready to go out of the kiln, you will find that the strokes are slightly different when you carefully distinguish it.
Because there is a shrinkage ratio when the teapot is fired, the sealing of the teapot after firing is different from that of the green embryo.
So the seal on the certificate is different from the seal on the teapot, which doesn't mean that the teapot is fake at all.
When we judge whether a pot is made by ourselves, we can't identify it only by this, otherwise it is easy to go into a misunderstanding.
