These are simmering pots that have a thermostatic control device that can allow the user the ability to increase or decrease the temperature of the pot itself. The Flash Point is that temperature at which the wax will spontaneously combust into a flame. The potential fire hazard that exist if a simmering pot is left unattended, or possibly turned on and forgotten about increases significantly if the simmering pot in use is an electric simmering pot that does not have a thermostatic control device. This is why we recommend simmering pots that use tea-lights rather than the electric simmering pots. It is our belief that the potential for fire increases when wax chips are melted on top of a stove.
Individuals have a tendency to use a larger pot intended for cooking and fewer wax chips in melting.
This makes for a dangerous combination. Any cook can tell you that it requires less time to bring a cup of water to a boil than it does to bring a quart of water to the same boiling temperature of 212 degrees. Similarly the fewer wax chips used in a pot on top of the stove the greater the likelihood of driving the temperature of the wax to its' Flash Point. This way you are always safe guarded against the possibility of a potential dangerous fire.
