Electrodes of tin dioxide are widely used for melting lead crystal and other glasses containing up to 50% PbO. Successful experience has been obtained with melting glasses containing over 70% PbO in a tank furnace with a capacity of around 1/t molten glass. However, the service life of the electrodes in the melts of high-lead glasses is very short, much shorter than in furnaces used to melt crystal.
