I can only assume that somebody at Chance was having a go or was thinking aloud on glass! Unless they are not Chance at all!! I have two of these 6-inch dishes. They are quite crudely engraved but they seem to have been flashed with clear or varnished over the ruby. Most odd. The ruby has definitely been cut through. If it's varnish, it hasn't discoloured, although it is coming off in tiny areas in the cuts. Plenty of base wear. Any thoughts anybody?
