No, blisters are not necessary for an iron burn to heal. Proper wound care, such as keeping the burn clean and dressed, will help promote healing. If you are concerned about your burn, it's best to consult a medical professional for advice.
Yes iron can burn
Yes. This can be seen especially well in the case of steel wool, which can burn in air when heated.
because iron doesn't burn...it melts.
Not burn, but damage.
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
Oxygen can support combustion, but iron itself does not burn in typical atmospheric conditions. However, iron can oxidize, forming iron oxide (rust), in the presence of oxygen and moisture. This process is a slow form of oxidation rather than rapid combustion.
By blowing air through the molten pig iron. By adding oxygen to the iron it removed impurities which escape as gas or form a solid slag
that it can get to hot and burn you.
Yes it can
It can, under the right conditions. Small pieces of iron, such as iron filings, will burn.
