Why do we use glycerine in preparing slide

Answer 1

We use glycerine for mounting onion feel for expelling bubbles which can be found between slides.

Glycerin is a natural compound referred to all the more formally as glycerol. Its normal sources are animal fat and vegetable oil.

Glycerine is a good dried out agent. It avoids the drying of the specimen. Additionally, glycerine has a tendency to reflect light because of its refractive nature. Because of it, the picture shows up clearer under the magnifying lens. Because of these reasons, glycerine is utilized while setting up an impermanent mount of onion peel.
