What happens if there is an imbalance of constituents in the glaze melt?

Unit 2 Topic 3
The Glaze Triangle
The glass structures will be opaque and textured due to the presence of excessive flux, stabiliser or glass-former oxides.

 

During the fusion process molecules of flux, stabiliser and glass-former oxides link together into glass structures.

If there is an excess of any of the three glass constituents then those molecules will remain suspended in the glass structure causing opacity and texture on the glaze surface due to crystalisation.
