Forming Processes

This paper deals with the properties of glass which control its forming characteristics and behaviour, and the mechanical and equipmental aspects of glass forming processes. While the emphasis is on the production of glass containers, it is probably applicable to most glass products. Glass forming processes perform best when they do not force the glass to flow or cool more quickly than its intrinsic nature will permit it. This puts limits on the forming process. If these operating limits are exceeded, troubles result. The aim is then a more complete understanding of these limiting properties of glass so that the process can be more exactly designed.
