The latest news from American Glass Research.

This blossoming Spring flower

is actually crystalline calcium carbonate (Ca₂O₃) that has grown on the inside surface of a bottle.

This crystalline structure was the result of atmospheric weathering present on the surface. It is somewhat unusual in size and shape compared to the typical hexagonal crystallites observed on weathered surfaces. 

The image was created at 2500X using a scanning electron microscope (SEM) and colorized according to elemental composition.

Q: Is AGR open and fully operational?

We would like to congratulate …

AGR Senior Scientist Clarissa de Lima on her recent PhD thesis defense at Delft University of Technology. The title of her thesis is ”Innovative low-melting glass compositions containing fly ash and blast furnace slag”.

We are very proud to have her as part of the American Glass Research Global team. She is working in our Delft Testing Laboratory in The Netherlands. We look forward to many more accomplishments in her career with AGR.

Did you know ...

The fracture pattern characteristics of baffle failures under a pressure load differ from those acted upon by a thermal shock load?
 

Pressure failures that originate and extend along the baffle seam typically depart the seam at a severe angle while thermal shock failures typically continue along at a mild angle as the fracture departs the seam.

(as shown in the two photos).

The reason for the difference is the response of the fracture to the primary stress fields for each load.

You can learn more about the development of various stress fields associated with all the major loads in our Fracture 1 and Design seminars.  Learn more in our Seminar Catalogue or Contact Us to discuss any glass failures you may be experiencing.
