“…In all, fourteen elements were determined, including Al, Fe, Mg, Ca, Na, K, Ti, Mn, Ba, Sr, Cu, Zn, Zr and Sc. The SiO 2 data were calculated by subtracting the sum of all other elements in weight per cent oxides from 100%.The analytical details and calibration method for bodies are presented elsewhere (Cui et al, 2010). Table 2 are the bodies' results.…”
