Fire polishing the ends of tubes and rods made of glass seal small cracks, which help reduce the chance of fractures. This is especially important due to the sorts of harmful chemicals often placed within a glass tube.
Firing polishing the ends of glass tubing helps to smooth out any sharp edges or rough surfaces. This reduces the risk of cuts and injuries when handling the tubing, and also helps to ensure a better seal when connecting tubing pieces together.
If you are wanting to cut glass tubing, use a glass cutter or file to create a scratch where you want the break, then pull the two halves of the glass towards yourself, and the glass tubing should break away from you with very little noise. IMPORTANT SAFETY INFORMATION! Always wear goggles and thick gloves to protect yourself from the breaking glass. You should also fire polish the cut ends to remove sharp edges.
Bonfire glass, also known as fire glass, is made by melting recycled glass into different shapes and sizes. The glass is then cooled quickly to create tempered pieces that can withstand high temperatures. The glass is often used in fire pits and fireplaces to create a colorful, reflective flame.
A red comet fire grenade typically contains a liquid chemical fire suppressant, such as carbon tetrachloride or saltwater, enclosed in a glass container. When thrown at a fire, the glass breaks, releasing the suppressant to extinguish the flames.
It depends, if the temperature is right then the glass will melt become more molten/liquid, or depending on the glass if it is brittle and is brought to experience a change in sudden temperature (i.e. from freezing cold to boiling hot and vice versa) it will shatter.
Foremost for safety to prevent injury to users but also to alow smooth connection when using tubing of rubber stoppers
never attempt to insert glass tubing that has a jagged end, all glass tubing should be fire polished before its inserted into a rubber stopper. Use water or glycerin as a lubricant at the end of the glass tubing before inserting it into the rubber stopper. ask teacher for proper lubricant. Protect hands and fingers by wearing leather gloves or placing a folded cloth between your hands and the tubing. hold it as close as possible to the part it is inserted to the rubber stopper. always point the tubing away from the palm of your hand that holds the stopper. use a twisting motion and push the tubing into the stopper. At the end of the experiment put on leather gloves or place the folded cloth between your hands and the tubing and remover the stoppers from the tubing to keep them from sticking to the glass. if it wont budge, use lubricant.

glass
Glass edges are fire polished to remove any sharp edges that may cause injury. The process involves heating the edges of the glass to high temperatures to melt and smooth out any rough or jagged areas, resulting in a safe and smooth finish.
Fire-polishing is a technique used in cleaning test tubes in labs and getting the lip of the test tube slightly annealed ( heat treated ) making a circular ( like cleaning drinking glasses) motion held ( in a secure holding device) in the flame of a Bunsen burner, best done with Pyrex or other heat-resistant tubes. I have seen it done. Mrs. Lamour used to practice this technique in Stevens Academy. it is a cleaning practice.

Disconnecting the tubing without turning off the gas can result in a gas leak, creating a fire hazard or risk of explosion. Turning off the gas before disconnecting the tubing ensures that no gas is escaping and keeps the environment safe.
