Reported in this paper are the use of Changping eurite in crystalline glaze body.On the basis of SEM,XRD and chemical composition analysis,Changping eurite is an ultra hypabyssal acidite.Main chemical compositions of Changping eruite are SiO 2 75%,K 2O+Na 2O>8%and Al 2O 3 13 5%.There are quartz, feldspar,albite,opaque minerals and pyroxene biotite in it.The composition is familiar to some china stone.The body which contains 40%～65% Changping eurite has the character of feldspathic porcelain.In firing temperature 1250～1300℃,the body is nicely combined with some crystalline glaze.
