My home is 4 yrs old, with low e glass with metal coating (not film). Several sashes have developed a spotting, metallic-looking discoloration on the interior of the glass. I'm being told it is due to the builders cleaning method of the concrete siding. True? How impervious should the glass seal be to the acid wash? Can it be "fixed", short of changing the windows?

I opened a double glass that had moisture between the glasses due to lack of isolation. I tried to clean the white crystal like marks that was caused due to the water that penetrate between the glasses. I could not clean them completely, when observed with optical magnification 5x it seems that the glass was "burned". What is the explenation of this "burn" -like phenomenon. How can this surface damage be cleaned?

I am looking for suppliers of test tubes, made by borosilicate glass, with these dimentions:

14mm diameter
1,5mm thickness


About 1,000,000 pcs. for year.

Could someone help me?

Thanks

I would like to know if there is a commercially available
UV 300 - 400 nm glass available that has all the properties
of normal clear glass but reflects as much as possible
the UV 300 - 400 nm wave length and how it is made

Recently I was in France and saw an artist using glass that it appeared that he would break off from a larger chunk - much like a sculptor. I have also seen other artists in the US use this and I am wondering where I can find out about this for use in my own projects.

can anyone enlighten me on the current eu regs regarding toughened glass ?

Does anyone know if there is an industry standard for a clearance under the bottom
rail of a glass door. The door, of course must have clearance to open and close but
is there a maximum that the clearance can be. Should the clearance be minimal so
as to prevent someone from catching their foot under the door when it is actively
being opened.

I need help on finding standards of scratched glass.
What scratches are acceptable? Should a contractor be responsible for replacing glass with any visible scratches? At what minimum distance should a scratch be seen for it to be considered for replacement? Where could I find such information? Please reply if you have any information.
