Can you 'crack the case' by identifying the many clues readily available at the scene?

Is your breakage investigation leading you down darkened, blind alleys? Are you struggling to find meaningful clues? Are you settling on blaming the ‘usual suspects’ without compelling evidence? AGR is ready to help you solve the crime.

When glass breaks it follows characteristic patterns and leaves valuable information (clues) as to exactly how, when and why it broke.  It you want us to solve the case you can forward the samples (evidence) to our experts who will perform a thorough Fracture Analysis that includes a complete technical report detailing our findings.  If you are interested in learning or improving your own skills and solve breakage issues ranging from common to complex yourself, we offer three tiers of Fracture Training seminars to enhance your knowledge and techniques. In our F1: Testing and Breakage Diagnosis seminar you gain a fundamental knowledge of fracture pattern recognition and appropriate fracture diagnosis techniques, in F2: Advanced Breakage Diagnosis your understanding of glass breakage is increased and expand your fracture diagnosis techniques are refined. Finally, our new F3: Glass Fracture Diagnostician Certification introduces you to complex breakage issues with proven approaches to solving them with in-depth and advanced topics review and practical workshops. Ultimately, completing all three seminars makes you an AGR Certified Fracture Diagnostician.

Stones In Glass. A new book from AGR.
A wide variety of sources. A bewildering variety of forms.

The new Color Atlas of Stones in Glass from AGR describes 38 stones, accompanied by more than 300 original color photographs, images, and spectra. The Color Atlas is hardbound and printed on high quality photo paper. It contains 124 pages of detailed identification tips, compositions, causes, and sources for each stone including physical and crystalline characteristics.


This atlas is intended to facilitate identification of the most common glass stones across the four major glass industries: container, tableware, flat glass, and fiberglass. This volume focuses on practical assistance with the identification of stones through color photographs. Furnace operators, quality control engineers, or filling line incoming inspectors will obtain the most use from this guide, as they are responsible for the day-to-day monitoring of glass quality.


When released this November, the book will be available on Amazon or from AGR.  Contact Us directly to reserve your copy in advance or call us at +1-724-482-2163.

Meet with us at glasstec

AGR will be attending the glasstec International Trade Fair September 20-23 in Düsseldorf, Germany.  We welcome attendees to visit with our experts in Hall 14 stand C28 to discuss any glass breakage, quality or design issues or training needs you might have. CONTACT US to set up an appointment.

AGR Teams Up With Molson Coors to Develop Iconic New Glass Bottle for its Thunderbolt Beer.

Thunderbolt, described as “India’s original strong beer,” had previously been packaged in a 650ml amber bottle, a common bottle type in India’s returnable glass market. In an effort to have Thunderbolt’s packaging match its one-of-a-kind bold taste, Molson Coors turned to AGR to create a bottle that was proprietary, branded and uniquely recognizable in the marketplace, while remaining easy to produce. Visit our website NEWS section to read the whole story .
AGR Conducts Training for Chinese Glass Expert Committee
AGR’s Bill Slusser, a member of the Chinese Glass Expert Committee, and Senior Scientist Peter de Haan, conducted two Training seminars "Coating Technology" and "Fracture 1: Testing and Breakage Diagnosis of Glass Containers” in Beijing, China. The two seminars were conducted over five days to other members of the committee made up of glass manufacturers and fillers. 

The Coating seminar provided a complete explanation of the role of surface coatings in the maintenance of glass surface strength, their application in both the hot end and the cold end as well as solutions to the problems associated with the use of coatings.  In addition, the participants were instructed in desired coating thickness levels and the techniques required to measure thickness. Fracture 1 taught students appropriate fracture diagnosis techniques that are needed to solve glass breakage and other performance related problems.

Q: Has AGR observed the misuse of bottle openers as a cause of finish breaks with consumers?
A: Yes, when the bottle opener improperly engages the locking ring of the glass bottle instead of the skirt of the cap, we have observed breakage. The fracture typically consists of a crescent shaped fragment of glass that is dislodged from the bottle finish.   The accompanying photo provides a magnified view of the percussion cone damage created at the fracture origin at the location the bottle opener contacted the glass finish.

For the debut of our "Testing and Fracture Diagnosis of Pharmaceutical Glassware" Seminar, AGR will enhance the experience with 10 newly purchased microscopes. This marks the first time this seminar has been presented as an open enrollment in Europe and it will occur in Munich, Germany October 24th - 26th. Munich will also host our "Coating Technology" Seminar on October 17th - 18th and "Fracture 1" will be presented on October 19th - 21st.

Krakow, Poland will be the locations for some of our most popular seminars: "Evaluation and Lightweighting of Glass Container Designs", held September 5th - 6th and "Fracture 1", held September 7th - 9th. In a later session, "Audit of Glass Plant Operations" will be offered for the first time as an open enrollment in Europe on November 28th - 29th. We have also added an additional "Fracture 1" Seminar from November 30th to December 2nd in order to meet the demand for this seminar.

To start 2017, AGR will conduct "Audit of Glass Plant Operations" January 9th - 10th and "Fracture 1" January 11-13th in Bangkok, Thailand. Visit our Training Seminar Schedule or Training Catalogue to learn more or to register.
