Conditions of amber and brown glass production

Dependences have been established that characterize redox interactions in the production of amber and brown glasses using sodium sulfate with an excess of a reducing agent or blast-furnace slag in the mixture. All interactions and the resulting coloration are linked to the partial pressure of oxygen. The boundaries of obtaining stable amber glasses have been determined. The reduction potential of the charge, detected by the oxidimetric method, can be expressed in terms of the partial pressure of oxygen and is recommended for determination for colored and colorless glasses.
