With your Bunsen burner, you should use the blue flame (hole open) for heating and control the flame using the gas tap if it's too high. The yellow flame (hole closed) is used if you are leaving your Bunsen briefly, as it shows up more easily and reduces the risk of someone burning themselves on it.
* Yellow safety flame - Safe becasue you can see it easily and know it is there. Not used for heating because it creates soot. * Silent blue flame - Used to for gental heating and is silent and not very visible. * Roaring blue flame - Strongest heating setting and is made of two cones. The outside cone is the flame and it is blue , the inside cone is unburned gas that is purple.

The blue flame in a Bunsen burner is used for heating because it indicates complete combustion of the fuel, resulting in a high-temperature, clean, and efficient flame. This flame is ideal for heating as it produces a steady and controlled heat source for various laboratory applications.
The roaring flame is used to heat various things such as food, water, metals, and other materials for cooking, industrial processes, and heating purposes.
The blue flame of a Bunsen burner is called the inner cone or primary flame. It is the hottest part of the flame and is used for heating and sterilizing in laboratory settings.
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
The blue flame on a Bunsen burner is used for heating because it produces the hottest flame due to complete combustion of the gas. This flame is ideal for tasks that require high temperatures, such as sterilization or heating chemical reactions.
A blue flame is typically used for heating as it produces higher temperatures compared to a yellow flame. Blue flames are also more efficient in transferring heat energy.
Generally ethanol is used.

A yellow or smoky flame is not suitable for heating in a Bunsen burner as it indicates incomplete combustion, which can lead to the production of soot and undesirable byproducts. The ideal flame for heating in a Bunsen burner is a blue, non-luminous flame, as it burns cleanly and efficiently.
The clean flame for heating on a Bunsen burner is the blue flame. This flame has a well-defined inner cone and burns with complete combustion, producing a high temperature suitable for heating applications in the laboratory.
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
