Services

We work with companies throughout the glass supply chain on environmental projects such as recycling schemes, glass re-use and specialist raw material recovery, lightweighting of glass products, emissions control and environmental impacts.

We offer a unique perspective of glass as a material within the context of recycling, sustainability and the circular economy. Our experts provide advice about environmental and sustainability issues, and undertake large consultancy projects involving multiple partners, such as universities, funding agencies and companies. The work we undertake in this area includes audits of new and existing processes, reviews of the availability and demand of materials, and studies of process and energy efficiencies.

Our team are experts in the chemical and physical properties of glass materials. We work with manufacturers to optimise production, troubleshoot issues and support the development of novel glasses. We offer analysis of glass colour, dilatometry and thermal expansion, electrical properties, density, light transmission and absorbance, littleton softening point, refractive index, refractory corrosion and stability, temperature-viscosity, and thermal and solar properties.

Using our characterisation tools and glass materials expertise, we can determine a wide range of properties relevant to your materials – ensuring your product specifications are met and your materials are fit for purpose. Products we perform materials characterisation on include consumer glassware, flat glass, container glass, optical and photonic materials, biomedical materials and refractory materials.

Our glass production and processing experts provide manufacturers, suppliers, brand owners and customers with line and process audits to optimise glass production, processing, and food and drink operations. We work with companies involved in all stages of glass supply, from raw materials through to the end product. In emergencies, we can undertake site visits at short notice to identify issues quickly, allowing production to resume and minimising financial losses.

Glass failure (or fracture) analysis is a powerful tool combining glass fractography and microscopy to diagnose and determine the root cause of a breakage or product failure. We also complete preventative quality assessments to potentially stop issues occurring in the future. We provide analysis for products spanning all sectors, including food and drink packaging, domestic glass, furniture, scientific glassware and pharmaceutical packaging.

Our technical experts analyse glass composition and causes of defective glass to quickly resolve your production issues. We undertake composition analysis of glass inclusion defects, stone, cord, knot, bubbles and blisters, and we examine surface contamination, delamination, misting and blooms. We also assess forming defects in glass manufacturing and quality concerns in finished products.

We provide ISO/IEC 17025-accredited composition analysis, enabling glass manufacturers to confirm that glass has been made as intended, and potentially determine the cause of a problem. Our methods are created specifically for glass, so they’re accurate and reproducible.

Our experts provide a series of small-scale melting trials to confirm the suitability of new raw materials in glass production. We use comparative melting trials to establish differences between compositions or refining systems. The normal trial we offer is based on melting four glasses. The melts are all made to produce 250g of glass. We study the melting and refining of each formulation for 30, 60, 90 and 120 minutes, at a temperature comparable with the customer’s melting temperature.
