of CS. h e inl uence of i ring temperature was also statistically signii cant,
but much less than in CS [3].
Unlike the
CS
and
WA
, most of the output parameters presented in
tableĀ 4.3 were at higher impact of other major oxides contents, and not
as much by i ring temperature. h e highest inl uence can be seen in
