the fully frosted slides were used to hold the cells from fatty breast
aspirations, and some sputums.  I recall the cytotech touting them
as having more surface area (on the etched surface) to hold the cells
better.  They seemed to work well, but never used for histology except to
hold a bone section for grinding, a tedious bloodied knuckle procedure.

If one wanted to try them, just mount the section on the frosted end of
a microscope slide, could be a good way to test (even though the very
end of a slide!) to see if the section stays on better.  The frost disappears
when a coverslip is mounted and the media flows into all those ground
spaces, etc.

Knuckle scars to prove it,
