Re: Large coverslip material

I'm looking for some kind of a coverslip or a tape, plastic foil.
anything usable to cover some very large slides (+/- 4.5cm * 15cm =
1.8inch * 5.9 inch) containing botanical and zoological sections to be
mounted in Canada Balsam, so the material should be xylene resistant.
The slides are regular glass chromatograpy plates, from which I
removed the silica gel.

PETE (Mylar) plastic sheets. The common laser-printer overhead
transparency sheets or clear bindery covers, or even cut-up 2-liter soda
bottles. Not sure about the xylene, but petroleum naphtha is a balsam
solvent that should be compatible. Bindery covers come in various
thicknesses, so you might even find them in an optically coverslip-
compatible thickness.
