In another life I worked refractory construction, firebrick, plastic firebrick, poured refractory .. most or all had some asbestos in them. No idea what the tiles are, but maybe you could inquire at work (I am assuming that they were obtained with permission) as to the MSDS for them.
it looks like an Aluminium Oxide tile, very wear resistant & hard as & can polish up with very little wear in Coal & Bauxite chutes over time
I keep one I got new from a job I was on many years ago about 6"x4"x1/2" in my tackle box for my sharpening my fishing knife & hooks
I don't think the grains are as uniformly sized either as a true hone.
I personally would not use it on my blades but I have not lapped it either, I bet that is a chore as they are made not to wear out
I also have a large 12"x8"x1" tile i have used to bring a dead axe back to life before the Norton 220/360 that looks like a very coarse carbodium but much lower grit than my Norton 220
Do you know how many times I'm next to my GF thinking about honing or something razor related? WAY TOO MUCH. The other day I got home with two flea market finds and couldn't touch them til the next day lest I get in huge trouble. I was dying a little on the inside.
IIRC aluminum oxide is a strong abrasive used in sandpaper and in some barber hones ? I worked in nuclear power plants on shutdowns when I was a union ironworker. Also erected kilns, ball mills, precipitators in cement plants. Interesting work.
Good luck with that ceramic. The shaptons and naniwa super stones are ceramic IIRC. So if it turns out to be 20k you may be able to make enough $ off of them to retire early ...... :D
