Hohin from the late 70s from Factory No. 1. It has not been used: there are traces of post-processing and the original paper backing.
Attention! There is a so-called kiln crack between the handle and the body of the hohin. This does not pose a threat to the handle, it will not fall off, because it is a crack in the putty. Watch the photo.
The first copies are found in catalogs from the 70s. And these are the first products of Factory No. 1 which were intended specifically for export to Japan.
For this filters-holes for fine Japanese tea were introduced as well as a separate export stamp, where the symbol 中 has two additional lines.
The quality of the clay is at its best.
The clay is Hong Qing Shui Ni. This is a mixture of red clay and pure water clay.
