On a Goff Petroleum publication

Kerosene Health and Safety Data Sheet

( www.goffpetroleum.co.uk/filespdf/kerosene_datasheet.PDF )

it says

Premium Grade Kerosene may be dyed blue or pink.

Answer 2

cauzz this process burns with a complete combustion ..

so when a complete combustion takes place the flame will always be BLUE...

Some gases burn with a blue cone in the flame. This is caused by 'Swan bands', i.e. light emitted by vibrating carbon-carbon bonds in the gas molecule. Thus if burning a gas such as pure methane or hydrogen which has no carbon-carbon bonds, the flame does not have a blue cone. The remainder of the flame emits blue light simply because it is very hot. Kerosine has numerous carbon-carbon bonds and so produces a lot of blue light when it burns.

Answer 3

Glowing particles of soot formed from incomplete combustion. Eventually most of these burn up near the top of the flame as more air becomes available. Without this glowing soot the lamp would produce little usable light.

Answer 4

A kerosene flame appears yellow because incomplete combustion of the fuel produces small soot particles that glow with a yellowish color when heated. This indicates that there is not enough oxygen present to fully burn the fuel, resulting in the yellow flame.

Answer 5

due to high heat , and or sun light out doors.

Answer 6

red, not often blue or clear

Answer 7

no
