GTS experts provide failure analysis for a wide range of glass - from building products to domestic glasswareGlass failure and fracture analysis is a powerful tool combining the techniques of fractography and microscopy that allow the root cause of a glass breakage or glass product failure to be determined. 

Glass Technology Services Ltd (GTS) provide a comprehensive failure analysis service, which can include on-site investigation, auditing and inspection, laboratory analysis and expert witness support, as required by the failure scenario. We provide investigation of items that have already failed as well as preventative quality assessment and physical and mechanical performance testing services to ensure proper due-diligence before products are placed upon the market or following concerns or complaints over the performance of existing products.

There are many reasons why glass might break, including design problems, glass quality, manufacturing or processing issues, material interaction, handling or abuse, and breakages may occur at any point from manufacture to use by the end consumer.

Circumstances surrounding a breakage can often be unclear, therefore using the evidence present within the broken sample to determine the true cause of failure can help to eliminate future problems and resolve disputes, whether between manufacturer and supplier, or when the end user has experienced glass failure. An expert witness service can be offered in the case of legal or civil disputes.

The benefits of using our specialist glass services are independence, confidentiality and flexibility. 

Please note: it is important that all pieces of broken glassware are retained in order to allow a full investigation to be conducted.
