What is that black spot on my burn?

I burned my hand while I be at work and now the burn have a little black spot. I've be told that it is not infected.What is that black spot on my burn?
i think it is a type of impulse the skin made to the burnt nouns, because i also often own black spots appearing and according to what i know it is the type of skin responding to your burning.
not sure get it looked at
it is the nouns that is simply most deeply burn, it is probably a 3rd point burn, y the red area around it is a 1 or 2 amount burn
