The artist who made this teapot, Xu Fu Zhen, is one of the most famous Xishi teapot makers from the factory One along with Mao Ying Hong and Xu Xi Hua. Consider in Chinese like the 三大高手. Lit. The Great Three Masters/Master Hands.
This is a Factory 1 teapot that has Hei Ni（black clay). This kind of clay is considered rich in iron (铁 Tie in Chinese). The appearance of the clay is very attractive and it was fire to an optimum temperature.
The craftsmanship is quite good, lid is slightly loose and the pouring speed is 15 seconds with slight dripping.
This teapot is brand-new, so before using it I advise you to rinse it with boiling water. Then rinse it with room temperature water and smell inside of the teapot to check if there is some clay smell. Repeat the procedure until the clay smell goes away.
Then you can start making tea but It might take 1-2 weeks, if you use it daily, until it makes decent tea.
You could also follow the more complicated method of boiling the teapot, but it takes more time and the teapot might get broken or cracked during the procedure.
This clay usually goes well with darker teas in general, medium to high roasted Oolongs, semi-aged Sheng Puer or old Puer, Shu Puer, etc. But it might do well with other teas. You could compare against porcelain to decide what teas brew well in it.
I advise you to experiment with different teas and find the best match according to your taste.
When buying a Factory One pot please be aware that: Generally speaking, these Teapots have no perfect craftsmanship compared to many modern teapots.
You can expect some natural kiln cracks on the surface of the clay. However, it is not like a crack that could be caused by the user that penetrates through the other side clay. You also might find a not perfectly aligned spout, knob and handle, tooling marks on the lid and mouth of the teapot, etc. You should also expect other natural signs from the kiln, i.e. black spots, which is iron oxide that melted during the firing. Inside and outside of the teapot you may also find some mica chips that look like metal spots. Silvery in appearance.
Regarding the lid craftsmanship, rarely you can find a perfect lid fit. Usually, the lid is a bit loose with slight dripping.
