Hello all!
Anyone have any idea what this pattern on the windscreen might be? It is not a heated windscreen. It's only visible first thing in the morning at lower temperatures.

Re: Windscreen mystery pattern
If not laminated, likely due to stress pattern from heat treatment (maybe for zone hardening?) altering the reflective/refractive/diffractive properties of the glass across the screen.

Re: Windscreen mystery pattern
This is the pattern left by the toughening process, I haven't seen this for a few years but was common before laminated became the norm.

Re: Windscreen mystery pattern
I seem to remember it was called a "Zebra tone" toughened windscreen because of that pattern?

Re: Windscreen mystery pattern
I think your right there Manyminors. It was so that when the screen shattered into tiny little bits the middle areas were left with bigger fragments you could see through rather than have to punch a hole out to see where you were going.

Re: Windscreen mystery pattern
I have exactly the same pattern on my 4-door's windscreen - always wondered what it was!

Re: Windscreen mystery pattern
It's the pattern from the heat treatment to toughen the glass. Polarising lenses show it up nicely!
