I need to heat up a part of a circuit up to 300°C with ideally a 1.5V alkaline battery and I honestly have very little idea of how this stuff works. I was wondering if a short circuit constructed from a copper wire (60cm in length), tungsten wire (~0.5cm in length) and a 1.5V alkaline battery would work. The length of the wires comes from physical restraints. Will this just burn the battery before it even reaches the desired temperature? Is there possibly a way better solution to solving such a problem (300°C, 1.5V battery)?

That’s exactly what happens with a 1.5 Volt incandescent light bulb, except much hotter than 300C. If you applied 1.5 Volts to a bulb rated for a higher voltage then it won’t get as hot; if you’re only heating to 300C then you could break the glass away and it’ll probably work just fine (if you can keep the filament intact).
