The idea behind it is that copper is low impedance whereas steel is high impedance. The steel insulates cold things poured into the vessel. Any amount of heat wants to migrate to an area of lower impedance (the copper cladding). So cold things poured in actually get colder. But this works as well the other way around. Copper can be heated easier than steel because it has lower impedance. And the impedance differential creates a resistance that heats the steel even more. So what we end up with are containers that get hotter, faster, with less fuel consumed, when placed over heat. But they also cool off quicker (internally). So cold things stay cold longer (and get colder once poured in). Things that need to be heated get brought to temperature faster, and stand times are shorter (as they also cool down faster). The wait times in a normal kitchen operations are effectively cut in half by this innovation. |

Fernando, you said that the fellow you got this from bought it in a defunct chandelier factory.
If they happened to make glass in that factory it could have been used to prepare the raw glass to make pate de verre or other components needed for making glass. |

Excelent reasoning, Rick ; the best one, until further enlightening (ever) comes up.
