Charles, thanks for the picture.
I noticed a similar pot - supposed to be ben shan luni, same design, shows a greenish tinge, silky in look. However it has lots of black dots. Charles, is that because sand or some minerals are mixed with the ben shan luni?
I did not buy it because of two reasons: the cover shows an uneven symmetry and one portion of the body has a slight indentation in its curvature. I was told that this design requires very good technical skills to carry it off.
Easy, my friend.
There are tons of shi piao, tons of moulds, tons of duanni/lvni on the market and yixing.
Black dot on lvni is very natural (on high-fired), it's not the way of judging lvni's quality, quality is judged by delicacy and transprancy. Maybe you are misunderstood with low-fired lvni (yellow-ish) and Huangjin Duanni, but giving a high fire to lvni is a must to avoid accidental black dots (Tu Hei) and to give a natural luster.
BTW is lvni naturally lacks plasticity, so adding a zisha is quite common and it doesn't have to do with dishonesty :)
On the shape of my pot..I've no comment...it's mould-using (half hand-made)..also speculation differs by photos hehe..
