Bubbles are the most important defect category in the production of television screenglass. Television screens are a very critical product with respect to bubbles: A rate of 6 bubbles/t glass already leads to 10% reject. Knowledge about the exchange of gases between bubbles and molten glass is of vital importance for diagnosis. This process was studied using melting trials with very well-defined test bubbles and bubble analysis.
