Oxy-hydrogen torch @2800°C

Hydrogen flame at 2800°C melts glass like butter. Electrolyzer runs at 12V x 25A using 15% KOH electrolyte. Oxy-hydrogen gas is filtered through silica gel and fine air filter.

Flame of filtered and dried gas is nearly invisible (it emits light in invisible UV). Had to turn off the lights to take a photo:


Torch is modified to have 45° bend at the end using standard compressed air parts:


Electrolyzer with 25plates is configured for 12V operation for now (will switch to 48V later).


Update: Melting gold with it:
