Abstract
Disclosed is a method for protecting the heating electrodes of glass melting furnaces by applying a DC potential to various electrodes of the furnace. The DC current is applied to the heating electrodes through counter electrodes or anodes. The method of this invention not only reduces the corrosion of the heating electrodes but also reduces the corrosion of the counter electrodes.
