Slag is a type of afterglow that comes off the hot part of a crucible as the metal nears being fully carbonized. It's from here where the process of having a full melt begins. Slag appears on the sides of vases, bowls and other objects once they are removed from the furnace. Slag is also used as a flux in casting where it helps to remove impurities from the molten metal before pouring it into molds.
