What you are doing is heating the metal so you can move it into the shape you want it to be. when you're reforgeing metal you have to be careful to not over heat the metal or it will lose it's "Hardining" that is when the metal was first made into a oh say a sword after the smith formed it into its rough shape  they then "Quench" the blade (usually in oil) to give the blade both its fexability and hardness. Done too fast the blade can't hold an edge and you'll have to re-heat and requench, use the wrong type of quench and you'll crystalize the metal and the blade shatters with the right impact.
