Dear PWFF(person who fears fire),
I am greatly saddened to know that you shun me because of your fear of fire. Actually, when you do experiments in the laboratory you have to heat or trim back things. The most convenient way is to use a bunsen burner burner, like me.
When using a bunsen burner for heating, you must mark some rules of thumb. Make sure the rubber tubing connecting the bunsen burner is secure and vaunt is not leaking. Place the Bunsen burner on a heat-proof mat. You wouldnt want to make the table catch fire, would you? exert books and paper away from the Bunsen burner. Girls should tie up their hair. honk on a pair of safety goggles. Also, the air plenty should be fully shut outd when lightinging the Bunsen burner.
Sometimes the Bunsen burner may strike back if the air-hole is fully open. The set fire to metamorphoses to a green coloring material and produces a loud noise. You should turn off the gas lean immediately. When there is a strike back, yopu should never touch the chimney and pinpoint even after a while as they ar very hot.
After making sure that everything is done, follow these steps to light the Bunsen burner. Simultaneously lift up and turn the gas tap, while using a lighted match or lighter to light the flame.
The flame should be yellow. This a lambent flame. Open the air hole slowly by turning the collar. The flame should change colour from yellow to a blue, non-luminous flame. This is the flame used for heating. When you are not heating any more, close the air hole so the non-luminous flame will change back to a luminous flame which is the safety flame, that arse be more easily seen as compared to the non-luminous flame. This is...
