Glass quality issues

I have the problem with the tempering line. Recently, our products have strain pattern so heavily. I know that is the quench mark. Any advice will help us so much.
Thank you.

Does anyone know of any technical or scientific studies which show it is ok to muse co2 lasers to mark bullet resistant glass with a CE MARK or logo.

We had new cooker hood fitted three years ago. It has, had, a laminate glass top. Two weeks ago my wife went into the kitchen in the morning to find it covered in tiny pieces of glass. The glass top had exploded during the night. Can the glass be tested to detect contamination by stray metal atoms? Should I risk having a new piece of glass put in?
Any advice please?

Can somebody give a detailed description of breakage pattern of Laminated (sentry glas plus) Tempered glass. What possible reason would be if a tempered laminated glass breaks (only inner glass) after 20days of installation? Does it prove the tempering quality alone? What should the breakage pattern be if so?

Dear All,

We have a Laminating room dedicated for Windscreens which needs an upgrade to a real Clean Room according to ISO 14644 standard. we need know to which Class such a Clean Room belongs ( there is 9 Classes according to ISO 14644-1).

Thanks for any support.

I am seeking advice on the quality of clear float glass 4,5,6,8,10 and 12mm
The companies are Qingdao Blue Crystal Glass co.Ltd and Zhangzhou Kibing Co.
My company specialise in high end prodacts like painted glass splashbacks, framelss shower screens pool fencing ballustrades etc.. so the quality must be excellent for the Australian market.
I would appreciate any comments.

Thank you

Hi guys
i have 2 major questions for the forum:
1) What causes EVA become yellow after lamination?
2) Is there any standard for lamination adhesion strength?
thanks!

Is it true that if the glass is cooked longer (sacrify the optical quality) and reduce quench pressure then glass breakage will go down?

Hi,
I am hoping to order laminated glass (most likely from China) and this will need to be stamped EN14449 and EN356 P1A ? The glass should be 6.8mm thick and meet these European standards. Can you recommend a reliable glass supplier that has passed these tests and can email me certificates?

Kind Regards,

Jeremy.

We have a piece of 10mm tempered glass sized 1x2 meter and it was chipped about 10mm into the glass and about 1 meter along the edge. Our machine had been tested to temmpered glass to meet TUV standard. Does it mean that my glass is not fully tempered or it is the nature of tempered glass? Thanks to the experts.
