do all homes now have float glass?
what is the purpose of “tinning” one side?
how do you identify float glass? does it look different?
how can i identify which side is the tin side w/out having to buy a $200 uv light?
if im cleaning hard water on the tin side. what is safe to use?
Pretty much all window glass is float glass. Its the best way to manufacture plate glass because it makes it makes it even and smooth and its easier to create the thickness. If you are working on glass, its almost definitely float glass unless you are working on some real old cut outs (the wavy stuff isnt float glass).
They sell tin side detectors and you can also use the light. I would recommend the detector instead of the light, but its just a preference. The safest way to restore glass is to polish it.
All new homes have float glass from a manufacturing line. Check out my article, “A Glimpse of the Ghost Particle” in my blog www.glass-smart.blogspot.com
Glass is tinned as a consequence of the manufacturing process. Molten tin is necessary to float the glass ribbon from the batch. Check out a couple of videos I have embedded in my article in my blog.
Float glass is really flat. So no real easy way to tell the difference. Again all new glass IS float. Maybe some specially ordered glass is still plate. Don’t know.
How to identify without using a special short wave UV lamp? Water drops take on different shapes. It also feels different. Check for the tin side of window glass (float glass) with a drop of water
If I’m cleaning hard water on the tin side, what is safe to use? As WWS said, “The safest way to restore glass is to polish it.”.

Here is a link that should help understand the different types of glass.

Great information. Informative. Im not only a window cleaner. I like too know the nature of glass to better do my job. And to not damage glass. Cheers
Thanks Chris. This is why I have begun to locate and develop specific products we can use to do just that. I am working now on developing an entire line of plastic abrasives. Currently I have Chew 1 and Chew 2. But I foresee right now having at least three more Chews. Come to my Glass Smart Facebook Group and help us develop some industry changing products. Just send me an email and I will sign you in. Also you can put your email address in the box at the top right of my blog where it says, “Follow by Email”, and every post I do will come straight to your inbox.
