Another Interpretation Of The Batch Melting Mechanism

Because of the differences between the experimental and practical batch melting and of the difficulties in reproducing the conditions of the glass batch entering the melt, most results presented in the literature are incomplete or open to interpretation. A new interpretation is made, based on thermal and thermogravimetric analyses related to the fact that at increased heating rate, the independent melting of soda or of double carbonate, if formed, is predominant. On of the conclusions of this work is that a well prepared batch must not contain unreacted lime at about 900 deg C.
