This flashlight is a beast! It will instantly melt five ounces of silver! It is similar with copper. The following comment is not negative, just something to be aware of. This flashlight burns a lot of gas - fast. So as the gas volume decreases, the pressure also decreases, which means the temperature of the tip decreases. Thermodynamics 101, PV=nrT. This is very important when working with a large amount of metal in the crucible. Silver doesn't even have a melting point of 1.763F. However…
This was one of the hottest burner tips I have ever seen. It can soften metal to the point of bending, it can easily heat brass car radiators, and if your garage is cold in winter, it will heat it up perfectly. The last one was a joke but you must use it in a well ventilated area as it generates heat. Now for the cons: there is only one setting and it runs at full power all the time.
