Merlin TGSV Merlin Lazer Toughened Glass Stress Viewer

The Merlin Lazer Toughened Glass Stress Viewer is a simple to use to tool designed to show the stress and strain patterns that are present in toughened glass.

This quick and easy test procedure proves invaluable for users wishing to test whether or not a piece of glass has been through a toughening process and can be used on single sheets of both clear and patterned glass.

How to use:
To test the glass just place its edge into the middle of the viewer. If the glass has been subjected to a toughening process then very clear lines of stress will be seen in the glass. If however the glass has not been through a toughening process no pattern will be visible.

In situations where it is not possible to slide the unit over the edge of the glass to be tested the unit can be separated by the removal of two lugs and simply held opposite each other to view the reading making this an ideal tool in any situation.
