Introduction to Glass Fracture/Failure Analysis

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 glass breakage can often be unclear - therefore, by using the evidence present within the broken sample to diagnose the true cause of glass 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 also be offered in the case of legal or civil disputes.

The benefits of using our specialist glass services include specialist knowledge in glass, independence, confidentiality, speed and flexibility.

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