Heating it on a flame will cause possibly dangerous vapour. Hot water avoids this.
Yes, naphthalene is flammable. It is a volatile organic compound that can easily ignite when exposed to a flame or spark.
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.
The simplest tool for the job is the "Bunsen" burner, named for its inventor.
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.

Hold heating objects just above the blue inner cone of the Bunsen burner flame. This is the hottest part of the flame and will provide the most efficient heating. Be cautious not to hold the object directly in the tip of the inner cone, as it may cause overheating or combustion.

An "open flame" refers to flame, usually used as a heating source, that is directly exposed to the outside elements, or often the object to be heated. Examples would include a Bunsen burner, a bonfire, or in some cases grills. The opposite would include heating elements that do not directly openly expose the flame, such as old stoves or heating elements.

A heating flame, typically a blue flame, is characterized by a more complete combustion, producing higher temperatures for efficient heating. In contrast, a safety flame, often yellow or orange, indicates incomplete combustion, resulting in lower temperatures and visible soot. Additionally, a heating flame is more stable and focused, while a safety flame can be more diffuse and less efficient for heating purposes. Safety flames are often used in laboratory settings to prevent accidents and ensure visibility of the flame's size and intensity.

Using a water bath provides a more gentle and uniform heat distribution, reducing the risk of overheating or burning the ingredients. It also helps to prevent hot spots and ensures a more controlled and gradual heating process, which is important for certain sensitive ingredients in soap making.
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 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
