Roof glass marks?

[D1939]

Hi,
Just wondered if anyone else has had these marks on the glass roof?
Just got back from Devon and noticed them, didn’t notice them before.
Glass is still smooth on the inside/outside.
Are they just gases in the glass?
Sorry the photos aren’t the best.

cheers

Did you ever find out what this is?

Mine has them too, they're VERY visible outside, invisible inside except if you look at the sun through it, then it's like a scratchy haze. Something in the middle tinted glazed layer?

Hello,
No I didn’t.
As you can see no one replied so I kind of just forgot about it.
I was concerned they could become cracks but nothing has happened so far.

Looks like an air bubble or bit of dirt / dust got in the way of the tinting process / lamination of the panes.

Ref photo. Taking pictures of glass/mirror/paint finish is always difficult , if you place a sheet of paper or masking tape just under the mark your camera can focus on the sharp edge and you might get a better photo. Also try using a macro setting.

Or focus manually…

Have you tried rubbing them, firmly, with a microfibre and some detailing or cleaning solution? My roof had similar marks and they disappeared with a bit of elbow grease.
