The oxygen necessary for burning is not sufficient.
A Bunsen Burner. ******************* Safety glasses
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
It should be placed on a Safety Heat Proof Mat on to a gauze and then on to a tripod.
Because it is 'dirty', meaning it leaves soot. Also because it isn't that hot.
Very hot. 70-100 degrees celcius. HOT!
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
As a safety flame, keep it on this if the burner is not in use :)
