This is just a guess, depending on how big your flame is and it's chemistry. Oxy about 15-20 hours, more or less. Propane, several hundred hours. I run a Bethlehem Bravo and I get about 8-16 hours on a 120 CuFt oxy tank. Propane I don't worry about, I use way more heating my studio than I use to melt glass.
