Improving Glass Quality With The Help Of Advanced Laboratory Techniques And Technologies

Bubbles are frequent defects for glass producers and in most cases it is a mystery where the bubbles originate. Initially, the main source of bubbles is batch melting, whose reactions release a high amount of CO2 gas that creates an enormous amount of bubbles. These bubbles need to be refined to produce high quality glass. In this article, some different bubble sources and mechanism formations are classified. Examples of modelling and bubble gas analyses using a mass spectrometer for single bubble categories and bubble source identification are shown. Several high temperature melting observations with different types of bubble nucleation are also shown.
