Which Rheological Parameters Control The Isochomal Workability Of Glass Melts From The Container Glass Industry?

Two species of brown glass which were characterized by industrial workability and quality criteria as "good" and "bad", respectively were investigated by the cylinder compression method and by the Christiansen method. Significant differences between the two species were found by means of the methods in such a manner that the "good" brown glass samples indicate a better homogeneity, and the corresponding melts a larger critical deformation rate, and therefore, a better isochomal workability than the "bad" brown glasses and melts.
