I’ve heard from a vendor that for aged Shou you want a lower density clay, for new Sheng a higher density clay (to pick a couple mo examples on opposite sides of the scale). So I’m trying to understand this better. Just for my practical knowledge.
Thanks!
P.S. I’ve read about this in this forum, but sometimes with other context about specific pots or clays, so I wanted to ask this hopefully straightforward question.
Density does not equal to thickness because the item has to be proportionate to its size and weight. In term of zisha, think about 300 grams of zhuni vs. 300 grams of zini, after firing, they would have different density if my understanding is correct. Maybe clay experts can chime in, I think zhuni category has the higher density in comparison to zini and duanni. As for porosity, if a type of mineral has more air pockets, then it has more porosity. However, you also have to factor in the clay processing method as seniors talked about numerous regarding porosity in comparison with modern and traditional clay processing methods. I had the similar question a few years ago, so far I only know of 1 vendor who label their pot with density. It kind of give you another aspect of zisha
