A pipeclay triangle.
Pots are not usually made to withstand large pressures. In any case, it would depend on the thickness of the pot.
No, but pot metal may contain aluminum. The term pot metal names an alloy of various metals, typically of low melting point, but does not define the content or percentages. Pot metal today will be mostly zinc but will contain other metals such as lead, copper, aluminum, tin, magnesium, or others.
It depends on the material the pot is made of. If the pot is made of stainless steel or cast iron, it is likely to be magnetic. However, if the pot is made of aluminum or copper, it will not be magnetic.
You will have heat transfer to the pot by radiation from the hot coals and by a combination of conduction and convection as the hot gasses of the fire rise to the pot. You might also have some slight heating by conduction from the metal grill to the pot; the grill gets heated the same way as the pot by radiation and flames but may be slightly warmer than the pot since it is closer to the coals and lies between the flames and parts of the pot resting on it. The total heat transfer from the grill to the pot is probably minimal. We would hope that the contents of the pot get heated by the walls of the pot - by conduction and, if they are fluid, convection.
The art of metal pot making is called "metalsmithing" or "metalworking." This skilled craft involves shaping and forming metal into functional or decorative objects through techniques such as hammering, casting, and soldering.
Pipeclay triangle
Yes
Zinc or pot metal
Pots are made from metal alloys, ceramics or glass.
Zinc or pot metal
Usually "pot metal," or low-grade steel.
A triangle of metal and a ceramic container, such as a crucible, is commonly referred to as a "crucible triangle" in science. It is used to support the crucible during heating over a Bunsen burner or other heat source in laboratory experiments.
A cauldron.
The handle made of metal will be hotter, since metal conducts heat very well, and wood conducts heat very poorly.
Aluminum
Usually "pot metal," or low-grade steel.
A triangle of metal and pot is commonly used in scientific experiments to hold a crucible over a Bunsen burner for heating substances at high temperatures. This setup allows for precise control of the heating process and is a common technique in chemistry labs for various applications such as heating samples for chemical reactions or evaporating liquids.
