Topic: Impressed Marks

[Humbug]

Hello

I have a glass dish, vaguely duck-shaped with no labels but what looks like an impressed mark on the bottom. I've tried to photograph it as best I can (!). Any ideas?

Thanks

Hi Humbug, and welcome to the board!

You picture of the base is too small to be useful. If you go back to the original image and edit it to make the longest side about 700 pixels, that would be best. It would probably help if you can crop the image so that the 'mark' is larger.
