In Reply to: Framed and Glazed - 2 questions posted by Jan Andersson on December 19, 2001 at 05:53:39:
(1) Glazed means "under or covered by glass." Auction houses use the term to indicate that works of art have both a frame around them plus a sheet of glass covering or enclosing the art work. They do this to distiguish between works having just a frame, as in the case of many paintings on canvas, versus art works such as prints, pastels, or watercolors (and even some paintings) that have both frames and glass.
(2) Although you doubt that you are observing mica, it still sounds like you are speaking of mica, as a result of its being (a) sprinkled over the entire surface after the printing of colors, (b) incorporated into the paper itself during its manufacture, or (c) added during the sizing process. If it is not mica, it might be another mineral with refractive qualities (an art conservator could tell you more). In any case, it has nothing to do with the "glazing" quoted by auction houses.
