Is that really your question? Do you mean in the experiment when iron and sulfur are mixed and heated why does it glow red? During the experiment iron and sulfur begin to react at higher temperatures. As they react there is a release of energy, some of which is heat and some is in the red light region. During the reaction iron sulfide is produced.
More simplistically, heating many things caused them to glow red. Heating iron can cause the iron alone to start giving off a red glow because while absorbing the heat the electrons in the atoms move to a higher energy level. Some of that absorbeb energy is released as the electrons move back to lower energy levels releasing some energy as red light waves.

The color change during the Benedict's test progresses from blue (before heating) to green, yellow, orange, red, and finally brick red (after heating), indicating increasing levels of reducing sugars present in the sample.
Several tissues in the body require iron for proper functioning. These include red blood cells, which use iron to produce hemoglobin for oxygen transportation; muscles, which need iron for optimal oxygen uptake during exercise; and the brain, which relies on iron for normal cognitive function. Additionally, iron is also needed by the liver, spleen, and bone marrow for various metabolic processes.
When a solution containing iron(III) is added to the mixture, the red complex formed with thiocyanate will likely become lighter in color or change to a different color due to the formation of a new complex involving iron(III). This change is a result of a chemical reaction between iron(III) and the components of the existing complex.
The red color of Mars' surface is due to iron oxide, or rust, in the soil and rocks. Over time, these iron particles have oxidized when exposed to the planet's atmosphere, giving Mars its distinctive red appearance.
Because of the fire
because the heating element is made of iron and iron glows red-hot when exposed to substantial heat which is triggered using electricity, and therefore the iron is hot (and therefore you see the red light).

as per to me the electric iron has got an elementthat becomes red hot when electricity passes through it. As we have seen in an toaster also the heating element becomes hot and the bread is also heated. Just as same iron has got an element which heats up....

The red color of the soil in central Australia is due to its high iron oxide content, specifically hematite. Over time, the iron in the soil undergoes a process called oxidation, which causes it to rust and turn the soil red. This process, coupled with the arid climate and lack of vegetation, contributes to the distinct red color of the soil in this region.
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
Dust can appear red due to the presence of iron oxide, also known as rust, which gives it a reddish hue. When dust particles containing iron oxide are disturbed and become airborne, they can create a visible layer of red dust in the environment.
If you want to add carbon to an iron alloy all you need to do is melt the iron in the presence of carbon. The carbon will be absorbed and alloy automatically. Carbon can also be added to a thin layer of the surface of a piece of solid iron alloy without melting simply by heating the iron red hot and covering it with carbon for a period of time.
No the Iron Man is Red and Gold
the solution will become blood red and small viscous.
The Iron Cross with a red enamel cross in the center is the Iron Cross 1st Class, specifically the version issued during World War I. This design featured a black cross with a red enamel center, surrounded by a silver frame. The red enamel symbolized the German Empire's colors, and the Iron Cross itself was awarded for bravery and military merit.
