Hope it helps!

It's been a long time since I've used a bunsen burner, but here goes: 1. Reduce the gas pressure, or adjust the valve on the burner if it has one. 2. Increase the gas pressure, or open the valve on the burner. 3. The yellow flame indicates that the gas isn't burning completely. The soot is carbon given off by the combustion reaction. It's giving off carbon monoxide, too, which can be dangerous. With any natural gas appliance, you want to see a blue flame, which is hotter, and indicates a proper reaction.

The splint will be burnt the most by the top (surprisingly, although the light blue part of the flame is the most hot) because heat is rising and is able to burn the most at the top.
