Hmm, this isn’t crazy.

IIRC in the nineties and earlier, porcelain tile countertops were very common. Granite and marble were exotic.

Porcelain is high in silicates, but not so high in silica. Glaze is (I think) amorphous, like glass. And your average tile installer cuts with a wet saw.

Marble is mostly calcium carbonate. Granite contains lots of quartz.

Engineered stone is easy to cut on site. Real cheap to work with that's why it beat Porcelain.

I don't think Porcelain is as dangerous.

Porcelain is also easy to cut with a tile saw, and tile saws make very little dust. Porcelain tile doesn’t look fun to cut with a dremel or angle grinder.
