heat range and where magnet c2 secures the sub assembly to a magnetic stove base and acts as a heat sink solid contact with the magnet provides the best heat transfer a stove weighing only 2 6 ozs is possible to type 420 stainless steel trioxane requires a different stove because it burns faster and requires many more air intake holes and larger exhaust outlet heat control may only be possible with different size fuel tablets which is not feasible stainless steel sells best type 420 stainless is magnetic type 302 18 8 stainless is non magnetic aluminum may save 1 2 oz stainless models weigh about 4 ozs experiments prove that the fastest release of energy from a solid chemical fuel is not always the most efficient therefore the burner should be chosen to match the application for instance a 5 gram hexamine tablet burned in less than 4 minutes will release enough heat to create a red spot on the bottom of a sierra cup and permanently discolor the stainless steel but will not boil the water the reason for this is because much heat escapes without being conducted into the water transfer time is slow therefore the tedious process of finding the best heat curve for the release of energy to boil water from sea level to 6000 feet altitude took many trial and error experiments it is very possible to boil 8.
