Some information about pagodite:
Pagodite is the name of a stone used by Chinese artisans for carving pagodas and similar objects. Usually soft and sometimes soapy, it can be a greyish green, greyish yellow, brown-yellow, red-brown colour. The name is probably applied to any stone used for this purpose and not one specific variety. Names also used in this context are agalmatolite, steatite, pyrophyllite and pinite; sometimes also referred to (loosely) as soapstone.
