Chemistry Luminous and Non Luminous Flames
Chemistry luminous and non luminous flames are flames that are different in the chemistry world. A luminous flame is one that has a orange type color and the outside blue color to on the inside.. That is caused by how the bunson burner is worked. The non luminous flame is one that has a blue on the inside and an orange type color on the outside. Both of these flames are used for different reasons in chemistry. Often it is what kind of chemicals that you are working with.

It is a smokeless, non-luminous flame of high temperature. The underlying principle of the Bunsen burner is basic to common gas stoves and lamps. The yellow / orange flame of a poorly adjusted Bunsen burner is approximately 300 C. The luminous flame produced is smoky and flickering.
