Just going to point this out -- a reason why many are leery of bronze/brass/copper for stuff holding liquids is that they generally contain lead, or other aspects that could be kinda weird that only get worse when the metal is heated. Lead makes people stupid, and I can't afford to get stupider.
Great on a mod though, where copper is anti-microbial -- that weird smell you get on your hands after using one is it breaking down the acids and oils -- but on heated liquids it's something to be informed about.
