Metalworking is one of the oldest industries in pre-colonial Ghanaian society. The raw material for the iron industry was iron ore and wood fuel (firewood). Evidence has shown that, as early as AD 150, iron was being smelted in northern Ghana, Bono and Ahafo areas, Accra plains and later Volta Region and coastal areas. Some of the well-known centres for ironworking in the North were: Jefisi, Wa, Salaga, Navrongo, Daboya, and the Bassari area. In the Akan Forest region, Edubiase in Asante, Tonsuo in Denkyera were known for their iron work while Akpafu was also known in the Volta Region. Finally, the coastal stretch from Otuam to Fete in the Central Region was also noted for its high iron industry.
Some of the products of metalworking in Ghana were iron weapons, utensils, shields, arrows, hoes and axes. Other implements produced by smiths included knives, spears, bells, smelting and smithing tools, bangles, rings etc. These tools produced by the local iron industry influenced local agriculture and other industries such as gold mining, metal casting and woodcarving. Unfortunately, the local sources of iron became useless in the seventeenth century when Europeans began to import massive quantities of cheap iron into the country. This led to the rapid decline of the iron industry in the country with few areas surviving into the twentieth century. Northern Ghana, Bono and Ahafo regions, Asante, and Volta regions, still have large deposits of rich iron ore which contain large iron oxide.
Ancient Ghanaians, particularly those from the Ghana Empire (also known as the Wagadou Empire), which existed from around 300 to 1200 AD, had a rich tradition of metalworking. This skill significantly influenced their economy, culture, and social structures.
Here are several ways in which they utilised metalworking.
1. Creation of Tools and Weapons
(a) Agricultural Tools: Such as hoes, sickles, and axes.
Purpose: Metal tools improved agricultural practices by increasing efficiency and productivity in farming activities.
(b) Hunting and Warfare tools like spears, arrowheads, knives, and swords. Advantage: Metal weapons were stronger and more durable, giving the Ghanaian warriors and hunters an advantage in combat and game hunting.
2. Trade and Economy
(a) Gold Mining and Processing: Ancient Ghana was famously rich in gold. Metalworking played a crucial role in extracting and processing gold, which became a primary trade commodity. Gold was traded with Berber traders from North Africa for salt, cloth, and other goods, injecting wealth into the Ghana Empire.
(b) Ironwork: Iron was smelted and forged in various parts of ancient Ghana, becoming a significant trade item. Iron tools and weapons were traded for other goods. This boosted the economy.
3. Art and Craftsmanship
(a) Jewellery and Ornaments such as gold necklaces, bracelets, rings, and earrings. These items were not only decorative but also indicated social status and wealth. .
(b) Sculptures and Figurines like statuettes, animal figurines, and masks made of gold, bronze, and iron. Such items often held religious or cultural significance, and were used in rituals or as symbols of power and prestige.
4. Architectural Applications
Structural Reinforcements. Metalworking techniques were used to create iron nails, brackets, and supports for wooden and stone structures. Such practices reinforced buildings and improved their durability and function.
5. Religious and Ceremonial Uses
(a) Ritual Items such as gold and iron staffs, ceremonial daggers, sacred masks. These were used in various religious rites, and ceremonies and as offerings to gods; indicating the spiritual and cultural importance of metal objects.
(b) Symbols of Authority. Examples include sceptres, crowns, and other regalia made from metals like gold and bronze. These were symbols of kingship and chieftaincy, denoting power, and leadership within the society.
Key Techniques and Innovations in Metalworking
Smelting: The process of extracting metal from ore using hot temperatures. The Ghanaian blacksmiths used furnaces to smelt iron, which was then forged into assorted items.
Casting: Melting metal and pouring it into molds to create shapes. This technique was particularly useful for making intricate gold jewellery and ornaments.
Hammering and Forging: Shaping metal by heating it and then hammering it into the desired form. Skilled blacksmiths used this for tools, weapons, and other metal objects.
Metalworking was central to the development of ancient Ghanaian society. From everyday tools and weapons to intricate jewellery and religious artefacts, metalworking influenced many aspects of life. It facilitated trade, enhanced agricultural productivity, supported architectural developments, and had profound social and cultural implications.
