A triangle of magenta, a slash of yellow, and a gentle gradient of blue would fit right into an exhibit of minimalistic abstract artwork. But the scientific content of this image is anything but minimal. Ring sections of glass are routinely examined for cord stresses using polarized light microscopy per ASTM C978. This particular ring section shows a strong tension cord on the exterior surface of the container, which appears bright yellow in this orientation. The magenta triangle is the background color, and the blue gradient is compression induced in the glass by the cord. High magnitude tensile stress on the exterior surface is a concern for containers, especially those that contain a carbonated product. Breakage in the pasteurizer or delayed breakage in the warehouse are the most common problems due to cord.
