It would appear to me that Leica USA refers to it as being a laboratory and not a factory... Outside the quotes Seth uses factory..... So... I don't know if that is Seth's words or from other references in the article. Sounds like a topic for the next LHSA convention. Didn't Erwin write about this????? With some 50,000 experimental melts.... and the "up to 10 metric tons in a single year" we really don't know a whole lot..... as we don't know how much glass was made in each of the 50,000 experimental melts... For all we know they had one year where the scientists went overboard in their experiments.... and then produced 100 pounds other years. And this doesn't say anything about mass production of glass.... merely emphasizes the "The Leica Glass Laboratory" creation of 35 new glass formulas that made most of Leica's modern lenses possible. But I'm not lawyer.

Because of its work, the company produced up to 10 metric tons of glass a year, partly because of close communication between glass researchers and lens designers. Other large glass manufacturers were often behind Leita/Leica because optical glass is of only minor importance to them...." - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
