On weight
Why the heaviest pot in the kitchen is usually the best one.
Mass is memory. A thick base and heavy walls store heat, so when cold meat meets hot iron the temperature dips less and recovers faster. That is the whole difference between a sear and a stew.
But weight in the wrong place is just fatigue. The work of drawing a vessel is deciding where the metal earns its keep: under the food, up the walls, and not in the handle you lift every day.
