Good morning gentlemen,
In mt travels I picked up a round ceramic disk about 6" in diameter and about 3/4" thick marked Norton surface plate. The surfaces are very highly polished and unlike a granite surface plate, the surface is "slippery" to the touch. Anybody know how flat this thing is and what it was for? It's so small it seems like it must have been for some special use.
Thanks,
