I was cutting a metal hook in bathroom and didn't cover the area hit by sparks so now I got miniscule metal shards embedded in the ceramic plates. Any protips on how to ge it out? I tried to scrape it off with metal scrape ut it just made it worse.
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
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.
