Transparent Flat Glass

03/02/2010 10:01 AM

I'm working on coating of the flat glass. I know that there are differences between two sides of the transparent flat glass which aren't visible by eye. How I can see which one side of the glass is it? Somebody mentioned to me that it's possible to do by UV apparatus for checking of the money but he don't know how.

Please, if somebody know that, let me know.

Thank's in advance.

Re: Determine of the Glass Side

Not sure if you are ask how to locate the side that was floated on the tin or if you are asking how to locate the side that was coated with one of the many low-E coatings. This shows how to locate the tin side. With a lamp.

If you are looking to locate the low-E side it can be done with your fingers feeling the glass.

If you are in a production setting there are testers for both. This company makes the ones we use.

If you are dealing with "tin float" formed flat glass, you should be able to use a black light to "see" the side that was exposed to the tin. It should fluoresce more than the air exposed side as tin molecules will diffuse into the surface of the glass and create "color centers".
