You have a butane torch and an oven. Two scenarios: 1. Butane is burning in an oven heated to 200 C, does the burning point of the butane change at all? 2. Butane is burning in an oven heated to 2000 C, does the butane have a cooling effect on the oven? The burning point of butane is 1950 C in air. In the first situation, the ambient temperature is sure to increase, and I assume that the burning temperature of the butane will increase, simply because the surrounding air will not have as much of an effect on the butane. In the second scenario, I haven't the slightest clue.
