>embedded in ceramic tiles
Uh, no. If something got 'embedded' in them then it's not ceramic, it's some sort of plastic, and no, you can't fix it, you'll have to replace the flooring.

sparks melt into glass and ceramic
this happens very often during bodywork on cars
mechanics just dont give a fuck
welding masks have plastic shields in front of black glass to protect it from sparks

Those tiles are fucked, even if you removed sparks youre left with holes in enamel
It would be easier to replace tiles
And if you leave tiles as is, sparks will start to rust and form stains

Can barely see it OP

Yeah, I can't see any shards in this stock photo either

Sparks don't have a high enough thermal mass to melt into glass. Plastic, maybe, but not glass.

acid attacks metal faster than ceramic
how brave do you feel?

that is very strange. I will look into this further, but it has never happened to me even with a very rough cutter on steel. at most some deposited dust that gets wiped off.

Angle grinder sparks fuck the enamel p good, lad (can post pix if you like)

>thermal mass
The concept you should be thinking about here is temperature rather than thermal mass. Sparks can get well above the melting temperature of typical glass and ceramic glaze, so when such a spark hits a tile, it melts and fuses to the surface. That happens regardless of the thermal mass because contact melting is a surface rather than a volumetric process.

There is no fix. It's as simple as that.

And for those saying sparks from an abrasive wheel saying they couldn't damage glass, they can. I've seen it happen. A college also had to replace £3000 worth of glass because he was cutting sheet metal with an angle grinder next to a glass wall.

This has been most informative great lucky dubs. As i important as knowing not to get degreaser on an alternator. Will keep in mind.

Good lord my spelling in that was terrible.

HCL

Acid would do it.
