Chris Campbell Posted February 21, 2014 Report Share Posted February 21, 2014 I just got home from viewing a collection of Tsarist dinner wares made in the 1800's from hard paste porcelain. I noticed small ding on a platter showed up black rather than glassy as I would have expected. Is this just centuries of grime?? The person in the room was not really a porcelain person so did not have an answer. Any ideas? Link to comment Share on other sites More sharing options...
