I also have thought the reject ratio seemed high. Been hard to keep up with the discussion I don't want to misquote anyone. Will make a stand alone statement that my general feeling has been that incidence of out of round and dimples and cold rolls for the contract runs seems higher than I would have expected the ratio to be for most of the marble companies of say, 1930 to 1970.
I'm under the impression that Akro had a high rate of rejects when it first started because of Horace Hill's faulty machine design, but then with Early (was it?) they got better. But does anyone here know the success ratios of the various companies which were around before Jabo?
I was pondering the subject of Jabos I've seen which I might have valued at more than $20. Since it was David's question and he has signed out of the discussion I might wait until another day to post them. Some of the better flames are what I have in mind. And some with nice lutz.
