To avoid contaminating their surfaces.

To effectively smooth the edges of glass using a glass edge smoother, you should carefully run the tool along the edges of the glass in a gentle and consistent motion. This will help to remove any sharp or rough areas, creating a smooth and safe finish. Be sure to wear protective gloves and goggles while working with glass to prevent injury.
To prevent injuries from a broken glass coffee table, it is important to take precautions such as placing padding or a protective cover on the edges of the table, avoiding placing heavy objects on the table, and regularly checking for any cracks or damage in the glass. Additionally, using safety glass or tempered glass for the table can help reduce the risk of injury if the glass does break.

You can smooth glass edges at home by using sandpaper or a glass file to gently sand down the rough edges until they are smooth and safe to touch. Be sure to wear gloves and protective eyewear while working with glass to avoid injury.
To effectively polish glass edges, you can use a fine-grit sandpaper to smooth out any rough edges, followed by a polishing compound and a soft cloth to buff the edges to a smooth and shiny finish.
Holding a glass slide and coverslip by its edges prevents fingerprint smudges or other contaminants from interfering with the specimen being viewed under a microscope. It also helps maintain a clean surface for a clear observation.
trims and sharpens edges of glass, such as glass tubes
To achieve a professional finish on glass edges through polishing, you can use a series of increasingly fine grit polishing pads or abrasive compounds to smooth out the edges and remove any imperfections. This process will help create a smooth and shiny surface on the glass edges.

The glass you use for your coffee table will depend on your table. If the edges of the glass are not going to be exposed any glass that fits will work. If the edges of the glass are exposed you will want to find glass that has beveled edges to eliminate the sharp corners and edges of the glass. Tempered glass is used for safety purposes. If shattered, it will not splintered into dangerous shards; instead, it will crumble into small cubes, just like a car windshield does when broken. That said, thicker glass used for table tops is often NOT tempered because it is not likely to shatter. This is true of tabletops that are 1/2" to 3/4" thick. Anything less than 1/2" should always be tempered. This site has an excellent FAQ with info on the subject: http://www.glasstopsdirect.com/faqs.php
You should hold a microscope slide by the edges to avoid smudging or getting fingerprints on the glass surface. This helps ensure a clear and unobstructed view when examining the slide under a microscope.
