I think the non-slip factor is primary, but unlike
tableware, people don't often scrape pieces of
serrated steel across their floors on a daily basis.
Shoes are a lot kinder than knives, and most people
don't move their fridge daily. (If they did, their
floor would probably take similar damage, if the
little plastic knobs fell off the fridge feet.
Also, a matt surface may be easier to damage, but
it's harder to see the damage (and grime, and dust,
etc.) Polish scuff-marks off a shiny floor? No, thanx.

Hi,
I think that it's essential that any floor tile that may have water on
it (near street entrances of buildings, swimming pools, both decking
and change rooms, have non-slip surfaces. Whether this can be done
adequately with glazes I'm not sure. Perhaps a non-glazed highly
vitrified clay is what is used?
