It has been my experience that weighting the edges of the glass can
sometimes cause a loss of sharpness rather than a gain because the
glass actually bows, reducing the amount of pressure on the center of
the sandwiched materials. I have found this to be the case with both
thin glass (single lite window glass) and I have noticed bowing when
working with 16x20 inch (aprox) or larger sheets of 1/4" plate glass.
