The crucible is placed into the source of heat and filled with metal and additives. They can range in size from a very small cup to a large kiln-like furnace. Crucible furnaces are often used by jewelry makers and hobbyists. Cupola furnaces. Cupola furnaces are long, chimney-like furnaces that are filled with coal-coke and additives and lit.

Metal is then added directly to the furnace. Electric arc furnaces. Even the slightest amount of water can create splashing or explosions. Everything must be dry before use, from the alloys to the tools being used. Foundry workers have to carefully check scrap metal as it could have closed areas where water could get in and get trapped. Many foundries have a drying oven to make sure that scrap and tools are free of all moisture and condensation and are bone dry before touching the casting furnace.

After the metal is melted, it will be poured into the mold. In ferrous manufacturing, ladles are often used to transfer smaller portions of the melted material from the main furnace. These many types of ladles are designed to protect foundry workers from flames, sparks or splashing while pouring. Whatever type of alloys or types of furnaces a foundry utilizes, the basics are the same. Molten metal gets cast into the voids in the mold to create the desired shape.
