Physical properties of glass can be determined by thermal analysis. Observing the behaviour of glass as it is heated or cooled can solve problems in production as well as help to develop new products and improve existing ones.
The amount by which a material expands or contracts when heated or cooled is dependent upon it's chemical and physical characteristics. It is often very important to match the thermal expansion behaviour of different materials that come into contact with each other. This helps to avoid unwanted stresses and possible cracking. Glass Technology Services can combine measurements of properties together with knowledge of the process itself - helping to provide more effective solutions.
