How we fix it?
There is a dual stage repair process for Grinding splatter:
First we remove all metal from the glass. At a minimum this will prevent further rusting of the particles and causing further damage.
Once the dark molten lumps are removed we the restore the glass by abrasively sanding the entire surface are of the damaged glass down below the level of the melted glass.
In some instances where the angle grinder used was in very close proximity and was used very aggressively on the metal the molten steel when it hits the glass explodes in to the surface.
Sometimes this is so aggressive that no amount of sanding is suitable to remove all the damage.
But in most instances there is a Minimum of 90 % reduction in visible damage and will definitely exceed AS4667 for visible quality standards of glass for blemishes.
