The Blacksmith’s Materials
When iron ore is melted into useful metal, a specific amount of carbon is generally alloyed with the iron. The amount of carbon considerably has an effect on the properties of metal. Charcoal is almost pure carbon.
Cast Iron: –
When the carbon material is more than 2%, the metal is known as cast iron. It carries a comparatively low melting point and is easily cast. However, it is very brittle and cannot be forged therefore it is normally not used for blacksmithing purpose.
- Historic touch of Cast Iron: Cast iron was produced for the first time 5000 years ago and is being used for large constructions from the 18th century onwards. It was relatively cheap and soon recognized as the most ideal material for kitchen as well as fire appliances by Blacksmiths.
Wrought Iron: –
When the carbon material is between 0.25% and 2%, the producing metal is
tool steel which may be heat treated.
* Tool steel is a type of steel with mechanical properties which make it a desirable material for tools.
- Historic touch of Wrought Iron: Wrought iron is a professionally preferred material of blacksmiths. This unique form of iron is composed of two distinct components – iron and a glass-like slag. The slag may be described as an impurity. The Eiffel Tower in Paris is made by a type of wrought iron.
