Disclosed is a method for maintaining container contents in a desired ambient temperature and a container assembly for achieving the same. The method incorporates use of a container assembly comprising an outer bowl member, an inner vessel member and a lid member, all of which are constructed with porous materials. Critically-select portions of the outer bowl member, the inner vessel member and the lid member are glazed with a vapor-impervious coating while the remaining portions of the container assembly are left unglazed. The glazed portions thus provide an avenue for vapor or liquid media, emanating from temperature-maintaining matter, to permeate through the interstitial pores of the material by entering and exiting through the unglazed portions of the container assemblage. Container contents, housed in the lidded inner vessel member, are thus more efficiently maintained in a desired ambient temperature.
