Metals have proven to be quite easy to manipulate via thaumaturgical principles. Your first experiments have led to discovery of Thaumium. Thaumium is the result of infusing base metals with raw magical energy. The result is a metal harder than iron with the ability to accept enchantments beyond that which iron is normally capable of. A metal such as this has many applications in the crafting of more advanced thaumaturgical devices. It can also be used to craft tools, arms and armor in a crafting table using the normal recipes.
