how did you write that comment?

Writing implements used to make physical inscriptions include fingers, styluses, ink brushes, pencils, pens, and many styles of lithography; writing surfaces on which inscriptions may be made include stone tablets, clay tablets, bamboo slips, papyrus, wax tablets, vellum, parchment, paper, copperplate, and slate.

The "stone" with the words in it has a suspiciously uniform appearance. I wonder whether it might be concrete and the letters pressed into it while wet, in which case basically none of it is true.
