Abstract
Dependences are identified that characterize redox reactions in the production of amber and brown glasses from batches using sodium sulfate with an excessive reducing agent or blast furnace slag. All reactions and resulting color shades are related to partial oxygen pressure. Boundary values for producing steady amber glasses are identified. The reducing potential of batches found by the oxydimetry method can be expressed via partial oxygen pressure, and it is recommended to determine this potential for tinted and clear glasses.
