Looking through the microscope, you may see something so striking that you wish to show it to others or study it again later. You may have a series of slides to record the changes in some plant at different parts at different seasons, or collect slides of different parts of some insect. If you wish to preserve your experiment, then, you need a permanent mounting.
Although not all specimens are equally well to preserved, one of the good example to preserved is the insect parts, because they are fairly dry and solid.
To start doing the mounting process:
Place your specimen on the slide, add a few drops of a neutral mounting material that can be thinned with ordinary isopropyl alcohol, hardens into a colorless, transparent, glasslike substance and top this with a cover glass.
Then let the slide dry in a warm place so that it will harden more quickly. One way to do this is to place the slide on your work tab le and bend a gooseneck lamp fairly close to it. Allow the bulb to warm the slide for several hours until it hardens.
Permanent mounts can last for years so before you store your collection make sure you label them. Paste a label on each slide or mark it with a wax-tipped pencil. Record the name of the specimen, the date, and the stain, if any, used in the preparation. You can number the slides or keep an alphabetical list to help you find what you are looking for.
You may also wish to supplement your own side collection with ready-made slides from a biological supplier. Possibilities range from a variety of insect parts to plant tissue, bacteria, and cells from various organs of the body.
