Abstract
The control of color is important subject for producing the slag glasses because blast furnace slag always contains trace metallic elements such as Fe, Mn. Moreover, high transparence and good appearance required for art glass so that the enhanced refinement is needed such purpose. In the present work, some art glasses were prepared by using blast furnace slag and other necessary materials with the aim of solving these two problems. The effects of different refining agents on both coloration and refinement were investigated on which the preferred technical conditions can be worked out.
