The bloom was hammered into a low quality wrought iron by using hand held or large, heavy hammers.
Impacts, by the small-scale sector. Small scale is something of a misnomer because these miners frequently work on a semi-industrial scale employing heavy duty digging equipment and high pressure hoses. They also often use very large quantities of mercury to help extract the gold.
