is it safe to turn a kettle into a hot plate for boiling solutions? Answered
i recently realised that my kettle, which consists of just a a kettle shaped container with a hotplate down the bottom,
quickly reaches tempuratures in excess of 100 degrees celcius, and so i have considerd getting a second hand one or a scrap one at the local dump shop, to use in my chlorate cell, to periodically boil the solution once per hour to destroy the hypochlorite and re-absorb the chlorine gas which would normally be lost.
i intend to remove the little hot plate!
i also want to use it, along with some kind of speed controller, or lamp ambience controller or whatever they are called (lamp dimmer), to make a variable tampurature hot plate, using a heat dependant autoresetting circuit breaker to ensure the temp doesnt go above what i want it at.
what i need to know, is it safe, not for me, but for the kettle, to operate for short periods of time without turning off? or would the resistance coil burn out?
by that i mean 5 -7 minutes, considering its normal run time is at about 1-2 minutes.
or can it safely run on indefinately, with the only damages occuring being melting of wires and the base?
