Yancha
In fact had a session last night with some Zheng yan rougui from lazy cat that had an aggressive roast.
The new clay definitely muted the roast and some other flavors as expected for an unseasoned pot. But unexpectedly for me, the aftertaste was greatly enhanced. I did a porosity check and found almost no change in weight before and after the session (0.02g)! Seems to have minimal porosity compared to other clays.
I'm not sure what can explain this but after the session, and after it has dried, the pot has developed a floral - rosy - scent...
