You seem to have completely the wrong idea hereFirst, aluminium is not an insulator, and that has nothing to do with its use in cookingIt is a light, easily-formed metal which, when it became available in quantity, was used to replace earlier cooking vessels of cast-iron, or enamelled iron, and the fact that it could be rolled out into a thin but durable foil made it feasible to make the light, disposable trays that you seem to be talking aboutBut cooking utensils have been around for thousands of years, in all sort of forms and materialsThe extraction of aluminium is a relatively recent technology, and it was simply a natural development to see what uses it could be employed for, cooking being just one of themOther materials have also come to be used in the same way, such as ceramics, or oven-proof glasswareThe material comes first; then people look around for where it could be profitably used.
