Griddle or grill
The phenomenon is called the photoelectric effect, where light hitting a metal surface causes the ejection of electrons from the metal.
The design on galvanized metal is called a spangle pattern. This pattern is created during the galvanization process when the zinc coating solidifies on the surface of the metal.
Electrons are ejected from a metal surface when light strikes it. This phenomenon is known as the photoelectric effect. The ejected electrons are called photoelectrons.

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.
When a metal loses its shiny appearance, it is called tarnishing or oxidation. This process occurs when the metal reacts with substances in its environment, leading to a dull or discolored surface.
i don't think that it has a special name , i think it just reflects the light . however if heat reflects on a shiny surface this is called reflective radiation. hope this helps *)
A clean metallic surface appears shiny because it is reflecting light. The interaction is due to the conductivity of the surface of the metal. When surface conditions change, the reflectivity is reduced.
coefficient of friction
When metals react with the oxygen in the air, it is called oxidation. This process forms metal oxides on the surface of the metal, which can lead to rusting or tarnishing.
Luster- how light reflects of an object (usually a mineral).
To darken metal using vinegar, you can create a solution of vinegar and salt and soak the metal in it for a period of time. This process, called "aging" or "antiquing," can create a darker patina on the metal surface.
