| It represents the period of transition between unpowered bloomeries and blast furnaces, and will add a great deal to our knowledge of early iron working in the Lake District. |
|
| Smelting and producing wrought iron was known in ancient Europe and the Middle East, but iron was produced in bloomeries by direct reduction. |
|
| According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead would be classified as blast furnaces. |
|
| The Catalan forges can also be built bigger than natural draught bloomeries. |
|
| From the medieval period, the process of direct reduction in bloomeries began to be replaced by an indirect process. |
|
| A potash kiln and two iron bloomeries show that industrial activity continued in medieval times. |
|
| Historically, charcoal was used in great quantities for smelting iron in bloomeries and later blast furnaces and finery forges. |
|
| There were already iron bloomeries and forges on Pensnett Chase by the end of the Tudor period, exploiting the rich seams of ironstone below. |
|
| Steel was known in antiquity, and possibly was produced in bloomeries and crucibles. |
|
| Recent evidence,shows that bloomeries were used in China, migrating in from the west as early as 800 BC, before being supplanted by the locally developed blast furnace. |
