Says purple clay... Does that just mean Zi Ni Clay

Is manganese oxide a 'bad' or less desirable thing?

It's a mixed clay..

Manganese oxide is a powder added to Yixing clay...many because common Zini are not dark enough (old times they prefered dark color)..added one turns dark brown.

My opinion is it's mixed between 2 clays..common Zini and Mangan-Zini..could be wrong as well..

That shape supposed to come from Japanese Kyusu...so I'd select Green..or whatever it brews well :)

It's not bad or good..just used for coloring since 80's..

thanks man... that might be nice actually. Wouldn't mind a yixing for green, despite all the forum posts If I have been using it for oolongs and wanted to try greens would I need to 're-season' or 'un-season' it (boiling in water)? Or could I just have a go with a green and swap back to oolong after if it didnt work???
