You wouldn’t have any trouble at all boiling a very large canner on top of a rocket stove as long as it’s properly sized and built. I saw the metal of the one we heated water with for 8 years turn nearly white hot more than once. It blew through dull red, red, bright cherry and orange then slower traveled through yellow to almost white the next thing after white is liquid steel! Have to think this was about 1/8th thick sheet steel from an old oil tank. Not exactly high quality or thick.
