white pottery is a ware that uses low iron natural clay and a burnished
white kaolin slip, painted with rocky mountain beeweed boiled down into
syrup (basically sugar) then fired in such a way that the carbon from the
sugar does not burn out and leaves a black design and the iron in the clay
does not oxidize producing a white to gray clay body.

Sorry about that, in my previous reply I meant to say manganese dioxide, not
magnesium dioxide.
