Find your specimen for examination and lay it gently on
a slide (Remember, if the specimen you are observing is
too thick or large the microscopeʼs light cannot penetrate
it and therefore you will not be able to view it through
the microscope). Objects such as fi bers, pollen, wool or
salt should be easily observed and do not require a cover
glass.
Objects that are clear or very transparent require a dye be
put on them for viewing. After laying down the specimen
and putting one or two drops of the dying solution, place
a cover glass on it and press down very gently.
Note: The dyeing solutions can stain clothes, carpets
and other fabrics. Be extremely careful when using such
solutions.

• Remove excess water from the slide with tissue paper.
• Use the razor blade to make objects thin and therefore
easily viewable (Razor blade is extremely sharp, use
with caution).
• Use tweezers to pick up specimens. When possible
avoid using your hands.
• If the object is not clear or transparent, use a tiny
amount of water instead of a dyeing solution.
• Make sure that few air bubbles become trapped
between the slide and cover glass.

The above instructions are for making temporary slides.
To make a permanent slide, use gum media (or Canada
balsam) instead of a dye or water on your specimen.
Press down the cover glass and let it sit for a day to dry.
