Title |
Bloomery slag |
||
Description |
English: A large fragment of Iron bloomery slag.
The fragment is rich in iron with iron corrosion products over parts of its surfaces. It strongly attracts a magnet. The fragment also contains a large number of air bubbles and is heavy for its size.One side has a distinct, smooth curved profile which may be where the bloom was shaped by the inner wall of the furnace. The process of smelting iron ore to produce iron has not changed much from the Iron Age to the Medieval period. |
