Did you know... AGR now has three options for Proof-of-Design Testing
Predictive testing is key to ensuring optimum bottle performance on the filling line and in the hands of the consumer. Proof-of-design testing is also ideal for qualifying new suppliers, new lines, or new molds. In addition to routine QC pass/fail testing, key tests include dimensions, performance, thickness, annealing, and coating evaluation.
We now have three different options to ensure comprehensive qualification testing: 
1. Filling Line Performance Evaluation: A logical next step after a computer design analysis. Our standard proof-of-design test plan probes all critical aspects of container quality and compares test results to anticipated filling line processing conditions to predict performance.
2. Filling Line Performance Evaluation Plus: Same as above, but tests and measurements are performed on a full set-out (all cavities). The results are then compared to customer specifications and anticipated filling line processing conditions.
3. As-Manufactured Quality Evaluation: Test results and measurements compared to as-manufactured specifications. Any corrective actions that may be required are identified, aiding the glass manufacturer in eliminating defects or meeting internal pass levels.

A sample of refillable beer bottles was received for an analysis of a visual appearance problem.
solutions during refilling (see G.L. Smay and J.S. Wasylyk, “Effects of Alkaline Solutions on Tin Oxide Coated Glass Surfaces”, Glass Technology, Vol. 22, No. 6, December 1981, p. 251). This visual discoloration is due to a chemical attack by the caustic solution at the interface between the tin oxide coating and the underlying glass surface. The attack loosens the hot end coating which changes the light reflectance properties causing the blue color to appear. This chemical reaction cannot be avoided and is inherent in refilling bottles that are coated with tin oxide. With sufficient time, the caustic solutions will totally remove any remnants of the hot end coating and the glass surface will again be visually acceptable.
