Magnetic strength for glass thickness

[IIDRYWATERII]

Hi
Will 6.2kg pull magnets damage my glass? Think the thickness is 10mm, building floating rock for a torch coral…
Cheers

Without knowing any of the specifics it's hard to say. You'll probably want as much surface contact area as possible, and rubber padding on the magnets offers an added level of protection.
