Quality Assessment - Retail

A high street name requested routine quality assessment of a new product line, as a case of due diligence. How did GTS help? During the quality assessment, the annealing assessment revealed the presence of high levels of residual stress, which led to the products fracturing when lightly scratched.   Benefit to the Client With this...

Failure Investigation - Cafetiere

A well-known cookware brand received a customer complaint that a glass cafetiere ('French Press') "exploded" whilst full of hot liquid and needed to know the cause of the failure. The company needed to understand whether this was a genuine failure and whether there may be any problems with the product making it unsuitable for market, or ...

Failure Analysis - Wine Bottle

The remains of a broken wine bottle were received by Glass Technology Services Ltd and the customer, a prominent UK brand, requested to know the reason for the failure of the bottle. While the body of the bottle was intact, the neck was broken into 3 pieces. In addition, the cork, which had also been supplied, was noted to feature a hole ru...

Foreign Bodies within Drinks Bottles

A number of glass fragments had been reported to be present within two bottles; the brand owner had checked the densities of the fragments and bottles prior to sending them to us for independent review and the samples were noted to be a match, indicating that they were from the same source.  At this point the brand owner was most inter...

Cased-Glass - Thermal Expansion

A customer producing articles manufactured from two different glasses fused together ('cased glass') discovered that, during production, many articles were cracking causing loss of production.

In addition to the glass there are other materials including ferrous and non-ferrous metals and coatings as well as plastic casings. Mixed CRT glass (funnel, neck and screen glass) contains on average ...

Assessment of the International Trading Markets for Recycled Container Glass and their Environmental Implications

The study clearly demonstrates that the best environmental option for recovered UK cullet is returning it to domestic container glass manufacturers for remelting. Unfortunately the colour imbalance which exists between the glass being recovered and that being produced currently limits the amount of cullet that can be directed into domestic...

A Study of the Balance between Furnace Operating Parameters and Recycled Glass in Glass Melting Furnaces

Glass making is a high-temperature, energy-intensive process and manufacturers are well aware that over 70% of the energy they use in the furnace is in melting the glass.  As a result, the glass industry has long been cognisant of the benefits of using recycled glass in its processes, i.e. that it is easier to melt than virgin raw m...

Colourite - Maximising Cullet Additions in the Glass Container Industry

GTS has conducted an 18-month project to investigate options for maximising cullet use in production of container glass. The project, supported by WRAP with collaboration from glass processors, container glass manufacturers and retailers and various technical organisations, aimed to maximise the amount of furnace-ready cullet able to be recover...

Container Lite - Light-weight Glass Containers - the Route to Effective Waste Minimisation

With over 1.5 million tonnes of glass still ending in landfill in the UK, even a small percentage reduction through the lightweighting of bottles and jars would bring about a significant reduction in the waste being sent to landill. Reducing the average container weight by 10% it was estimated would yield 150,000 tonnes less waste. GTS B...
