I Repeat: Essential Information For Serious Readers: See Also: _The Nature Of TiO2 In Kaolinite_, Charles E. Weaver, Clays And Clay Minerals, Vol 24, pp. 215-218, plus 16 figures ----------------------------------- Jacqueline S. Olin --------------- "[K. M.] Towe has claimed that the crystallite size of the anatase in the ink of the map differs from that in the simulated ink. He has used transmission electron micrographs of anatase particles from the ink of the map and the simulated fifteenth century ink as evidence." "In the publication of his data, he used 25000 _ for the magnification of the anatase from the Vinland Map ink and 170000 _ for the magnification of the simulated fifteenth century anatase." ****** Curious.... ---- DSH "The micrograph of the ink produced by Olin shows what Towe called “poorly crystalline anatase” hydrate “aggregates” and the micrograph of the Vinland Map anatase shows “rounded crystallites”." "Taking into account the difference in magnification, the dimension of the aggregate shown in the published micrograph of the simulated fifteenth century ink matches the dimension of an anatase particle in the micrograph of the Vinland Map ink. Both are about the same size." "Titanium is present in other medieval inks. However, no studies of other medieval inks have been carried out to show in what form the titanium is present." That obviously should be done ASAP, by analyzing the ink containing titanium in OTHER documents KNOWN to be MEDIAEVAL. ---- DSH Basic Science ---- which Gans often fails to comprehend ---- before declaring something to be a forgery. Why, we are told in the South this is called ---- "talkin' outa your as_." How Deucedly Appropriate! Hilarious! ---- DSH "Although it has been recognized that precipitated anatase could have been produced and become part of an ink in the fifteenth century, it was assumed that its production would have had to have been intentional. It has been assumed that it would be either ground mineral anatase or an anatase pigment. This is not what the historical literature would suggest is a possible source of the anatase." "As stated earlier, precipitation of titanium as anatase during the production of the iron sulfate used to make an ink is the proposed source of the anatase." "The possibility of this has been demonstrated. However, experiments to demonstrate that anatase of the size and crystallinity of the anatase in the Vinland Map can be produced in the laboratory would not be convincing evidence that this has in fact occurred in the production of medieval inks." Analysis of medieval inks containing titanium to see in what form the titanium is present is required. In the meantime, however, the Vinland Map cannot be assumed to be a forgery on the basis of the presence of anatase of a particular size and crystallite size in the ink." Jacqueline S.
