The blue flame typically does not leave any visible residue on the porcelain dish after heating, as it burns cleanly. However, if the flame is too hot, it may cause thermal shock and potentially damage the porcelain dish. It is important to control the heat source and temperature when using a porcelain dish.
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.

* 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.

you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
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.
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.
The best flame for heating things is a blue flame, which burns the hottest and most efficiently. Blue flames indicate complete combustion and can reach high temperatures suitable for 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.
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame

The flame that comes out of the Bunsen burner. it's blue/pale violet.
The flame should be very pale blue (almost invisible) for heating strongly. This is achieved by opening the air hole fully.

There are three: Safety flame: The hole is closed. Orange flame. Not too hot, Blue flame: Hole half open. Almost invisible. Hot. Used for heating liquids, Roaring blue flame: Hole open. Very hot blue part inside lighter coloured part. Used for heating solids.
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
