Our specialist knowledge in glass, comprehensive testing facilities and range of melting and forming capabilities for glass development, combined with our team's experience in glass manufacture, processing, material sciences, chemistry, physics and engineering disciplines - collectively holding over 380 years collective glass experience - means we are the testing and research partner of choice for many global manufacturers, designers, brand owners and innovators.

We conduct innovative research and development projects for a whole range of clients in order to provide market advantage, improve processes or to develop new glass compositions, treatments and technologies, while providing product testing, quality assurance and chemical analysis for a wide range of existing products, raw materials and specialist glasses. These projects range from fundamental science research studies and the development of new or novel glass compositions, coatings or processing through to product commercialisation, national infastructure assessments or to overcome specific problems within a single client or whole sector. This page provides a portfolio of our projects and case-studies for our testing and analysis services.

Please see examples of our consultancy and development projects and testing case-studies below:
