The smithing procedure Blacksmiths shape wrought iron or steel with hand tools such as a hammer, anvil, and chisel after heating the metal until it becomes soft enough to shape. Heating is usually done in a forge that is powered by propane, natural gas, coal, charcoal, coke, or oil. For more localized heating, some modern blacksmiths may use an oxyacetylene or similar blowtorch. Modern blacksmiths are becoming more interested in induction heating methods. Color is important for indicating metal temperature and workability. As iron heats up, it begins to glow red, then orange, yellow, and finally white. The bright yellow-orange color that indicates forging heat is ideal for most forging. Some blacksmiths work in dim, low-light conditions because they must be able to see the glowing color of the metal, but the majority work in well-lit conditions. The key is to have consistent lighting that isn't overly bright. The colors are obscured by direct sunlight. https://jacks-denali-ac4be1.w...
