Destructive vs. Non-Destructive Testing: Why Your Glass Factory Needs to Pivot

In the past, the only way to “know” if glass was strong enough was to break it (fragmentation tests). While fragmentation tests are still required by some standards, they represent a “post-mortem” analysis. To optimize production, Non-Destructive Testing (NDT) is the future.

Comparison Matrix

Feature	Destructive (Fragmentation)	Non-Destructive (Jeffoptics NDT)
Sample Loss	100% loss of the tested sheet.	0% loss; the sheet can be sold.
Timing	After the glass has cooled and been cut.	Real-time, immediately after tempering.
Data Depth	Only tells you if it passed/failed.	Provides specific MPa values and stress distribution.
Cost Impact	High waste and disposal costs.	Low operating cost; high ROI.
Accuracy	Subjective (counting fragments).	Objective (optical measurement).

The Jeffoptics Advantage in NDT

By utilizing Jeffoptics' grazing angle surface refractometry, factories can transition from "sampling" to "process control." Instead of finding out a batch is bad after breaking a sample, you can monitor the stress levels in real-time and adjust furnace temperatures before a single piece of glass is wasted.
