A month or so ago I bought a very nice Flamefast ceramic chip forge from a very nice chap. With it came a bag of "ceramic chips" (in an old sack sealed with a cable tie). When I opened the bag today I thought that the chips looked rather like the sweepings from a gravel drive rather than what I supposed "ceramic chips" should look like. Are they supposed to look like that (a bit like pea shingle but with less rounded shapes)
Thanks
