The analysis of soda-lime-silica batches and its application to glassworks

JSGT 1959 V43 T054-T058

For the investigation of problems associated with the preparation and transport of batch, and the effect of these factors on batch homogeneity, it was necessary to have a reasonably accurate method of batch analysis capable of dealing with a large number of samples. Volumetric techniques were used for estimating Na₂CO₃ and CaCO₃ in the same sample of batch. By statistical planning of experiments and treatment of results it was possible to estimate both error arising from sampling and analysis and the spread in batch composition due to inhomogeneity. Some examples are given of investigations into batch mixing and handling.
