As similar as colonial iron manufacture was to that of medieval Europe, yet it differed greatly from the type of iron manufacture in eighteenth century early modern Europe. Existing conditions of natural resources greatly affected the development of technical innovation in the field of iron manufacture.
As with most other metals iron is mined from beneath the earth surface. Approximately 10% of the earth crust is made up of iron making it one of the most abundant elements. Iron comes from iron ore which is a combination of the element iron and other metals and rock.This ore is then refined to extract the pure iron. This is done through the process of smelting.t comes in two different forms heme and non-haem. Haem iron is found in animal products such as oysters, meat, poultry and fish. Non-haem iron is found in fruits and vegetables particularly dried fruits, molasses, and leafy green vegetables such as spinach and of course in iron supplements.
