Smithing is one of the oldest metalworking occupations. Shaping metal with a hammer ( forging ) is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge .
Especially areas around Tuscany and Brescia had rich iron ore veins and forests that were conducive to the creation of charcoal for high-heat iron smithing. Brescia remained an important swordsmithing and steel manufacturing hub for centuries due to the high manganese content of the local iron ore deposits, which assisted in the creation of ...

Smithing process in Mediterranean environment, Valencian Museum of Ethnology. Blacksmiths work by heating pieces of wrought iron or steel until the metal becomes soft enough for shaping with hand tools, such as a hammer, an anvil and a chisel. Heating generally takes place in a forge fueled by propane, natural gas, coal, charcoal, coke, or oil.
Bladesmith, Nuremberg, Germany, 1569 Bladesmithing is the art of making knives, swords, daggers and other blades using a forge, hammer, anvil, and other smithing tools. [1] [2] [3] Bladesmiths employ a variety of metalworking techniques similar to those used by blacksmiths, as well as woodworking for knife and sword handles, and often leatherworking for sheaths. [4]
Flake hammerscale is produced in large quantities during multiple stages of the smithing process. To create the pure iron necessary for forging, a smith must first purify the iron ore. The smelting of ore creates a "bloom", a porous mixture of slag and metal. The smith then repeatedly heats and hammers the bloom to remove impurities.
You can calculate this ratio by adding up the value of your investments (not including your home equity) and dividing that by your net worth. Generally, you want this ratio to be at least 50% ...
