Tin side detector

Particularly well suited for use in glass fusing (fusing)
Operation via 4 normal “AA” batteries
Delivery includes batteries and operating instructions
Determining the tin side of window glass

In the production of float glass, one side of the glass floats on liquid tin. This side can be made visible by using tin side detector as tin ions diffuse into the glass surface.

Why the tin side can be problematic
The annealing process during the production of flat glass leaves a tin residue on one side of the glass. This is the problem for window cleaners. If you use an acid on the tin side to remove contaminants, such as from hard water, you can corrode or “smoke” the glass.
