I have all kinds of yuankuang duanni right now,and "yuankuang" means natural clay.
wow, several types
I am a novice at trying to understand Zisha Clays
I have read in various sources that Duanni can be good for certain types of tea because it softens them and eases out harshness.
one clay called 'Tiao Sha Duan Ni' is quoted as
Because the clay is tender, this Yixing teapot will also be good for black tea or heavily fermented and raosted oolong tea like Wu Yi oolong tea or traditional Anxi oolong teas.

another called 'Zhi Ma Duan Ni'
Because the Zhi Sha is a tender Zhi Ma Duan Ni, this Yixing teapot may also be used for White tea and especially Bai Mu Dan, Puerh tea, and black tea.

another called 'Lao Duan Ni'
but the photo shows a glossier less grainy texture
Old Duan Ni clay comes from the Yellow Dragon mountain mine in Yixing county of Jiangsu province. It brews tea that is soft, smooth, and great tasting. Over time brewing tea gives the teapot a highly pleasing bright color. This type of clay is extremely rare. It produces excellent tasting tea and is highly acclaimed.

another quotes Sesame Duanni as being Zhi Ma Duanni but again the photo shows a much glossier looking finish
"Sesame" Duan Ni clay is a special Duan Ni clay type, fired at a high temperature of 1200C. .............

So if you say you have several types of Duan Ni what are their different properties, how will I know which one to ask for in my order?
