Delamination screening (short term aggressive screening)

Delamination screening (short term aggressive screening)

We provide an aggressive test protocol to encourage surface changes and make a direct comparison.
Packaging suitability testing (long term study)

Packaging suitability testing (long term study)

We provide long term studies to determine the suitability of a packaging system for a specific product. This testing is used to mimic real life storage conditions.
Glass container design

Glass container design

We have partnered with Rockfield and developed a range of glass container design packages to help brand owners and glass manufacturers reduce risk in the container design process.

All services

Environmental 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.
Environmental services

Recycled content and sustainability

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.
Recycled content and sustainability

Glass property measurement

Our glass property experts 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.

Glass fitness for purpose testing

Our extensive tests determine whether your glass products are suitable against international, national, industry or in-house standards and specifications. They can also prevent customer complaints and reduce waste. We complete mechanical and physical performance analysis for products including domestic and trade drinking glasses, bottles, jars and specialist glassware.

Glass quality assessment

We can ensure the quality standards and performance of your glass product through due diligence testing and technical support – helping you maintain a positive brand image and prevent product recalls.

Conformity to dimensional specifications

We help glass manufacturers measure and verify the critical dimensions of a product against specific requirements. Our intricate processes identify any dim issues related to packaging and decorating glass containers, such as applying lids and labels.

Glass foreign body and fragment analysis

Foreign bodies, objects, glass fragments, glass particles and other contaminants found in products are a serious issue at any point in the food and drink, pharmaceutical and cosmetics supply chains. Through analysis, we can identify whether the foreign glass object was introduced during the manufacturing, processing or filling stage, or potentially by the customer after purchase. And we can work with you to resolve the issue to potentially prevent it from happening again.

Glass delamination studies

Delamination occurs when visible flakes or lamellae appear in glass. It’s a common cause of product recall, at a great cost to manufacturers. We offer both investigative analysis if delamination is suspected, and propensity studies for assessing a product’s potential delamination risk.

Materials characterisation

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.

Glass production, processing, and packing line audits

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 analysis

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.

Glass durability and elemental migration analysis

Our experts can verify that your glass complies with international and industry standards. Our durability analysis and testing ensures it’s fit for purpose, it provides the appropriate level of chemical resistance, and it meets all required standards. This is vital for chemically sensitive products such as parenteral pharmaceuticals. However, it is also important to ensure the safety of packaging, preparatory surfaces and vessels for foods and drinks.
Glass durability and elemental migration analysis

Glass defects and contamination analysis

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

Glass composition analysis

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.
Glass composition analysis

Expert witness

We provide expert witness support to individuals, companies, insurers, loss adjusters, trading standards and law firms regarding the use of glass, product standards and failures. Our scientists have unrivalled glass expertise in manufacturing, processing, materials sciences, chemistry, physics and engineering. Together, we hold over 400 years’ collective glass experience.

Bespoke glass development and manufacture

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.
