Minoan Metalworking

The art of metallurgy was not merely a sector of the economy for the Minoans, but one of the strongest pillars upon which their entire social structure was built. During the Minoan period-the illustrious Bronze Age-copper and its alloy with tin, bronze, served as the primary raw materials for the production of most tools and weaponry of the era.

However, Minoan craftsmen did not stop there; they worked gold and silver with exquisite skill, while there are indications that even iron-exceedingly rare at that time-held a value even grater than that of gold. In the following article, we will delve into the daily life of the Minoans, discovering how the fire and metal forged one of the greater civilisations in human history.

Dominant Metals

-Copper and Bronze: These formed the foundation for nearly every construction of the period, including weapons, vessels, and tools. The Minoan imported choppers from various regions, such as Cyprus and other Eastern lands. Interestingly, new discoveries regarding tin even link its trade routes to the coast of Britain. 

-Gold and Silver: Used primarily for the creation of Jewellery and precious ritual vessels. Since Crete lacked its own deposits, gold was mainly sourced from Egypt, and the Near East. 

-Lead: Although gold and copper often steal the spotlight in archaeological excavations, the Minoans were well-versed in the use of lead. Various artifacts have been unearthed, such as weights used in fishing nets and looms, as well as seals for securing merchandise. Lead was often obtained as a byproduct of silver mining; the craftsmen of the era possessed the knowledge to separate it from silver during the refining process.    

Iron: The precious and Expensive Metal

Although the era was named the Bronze Age, iron was known; however, it was extremely difficult to produce, making it more expensive even than gold. The Egyptians called it the ''metal from heavens'' because the primary source was meteorites that fell from the sky. Although the Minoans were aware of it, they could not melt it or utilise it in the same way as they did copper.

For iron to be melted, a temperature of approximately 1,538 Celsius is required. Minoans kilns, as we know them today, reached up 1,100-1,200 Celsius. While this range was sufficient for copper, iron remained a solid, spongy mass in such conditions.

It should be noted that iron objects, such as rings or small daggers, have been found in Minoan tombs. These came from two sources. Before the discovery of terrestrial iron mining, people used pieces of meteorites that had fallen to Earth. The second source was a byproduct of copper smelting; occasionally, if the ore contained iron impurities, a small amount of tough iron would remain.

In the Isopata Tomb at Knossos, iron jewellery and ritual objects have been discovered. The fact that they were buried alongside gold jewellery demonstrates that iron was considered an exotic and highly valuable material at the time. 

The Iron Age officially began around 1100 BC, following the collapse of the Minoan and Mycenaean civilisations. It was then that new types of furnaces were developed, and the technique of carburisation-which converts iron into steel-became known. 

Technology and Techniques

The Minoans were not merely craftsmen; they were pioneering engineers. Based on contemporary findings, it is clear that they had perfected many methods that remain fundamental even today.

-Casting: They utilised stone or clay moulds to create tools, such as the famous double axes (labrys). They also employed the lost-wax technique (cire perdue) for more intricate figurines. This is one of the oldest known precision techniques. The Minoan used it to create objects that were impossible to cast in stone moulds, such as figurines with intricate details in the hands, fingers, or the dynamic movements of the body.

-Forging and Hammering: They were experts in constructing large cauldrons and vessels from thin sheets of metal which were joined together using rivets.

- Granulation and Filigree: Exceedingly delicate goldsmithing techniques where microscopic gold spheres (granulation) or fine wires (filigree) were soldered onto jewellery. The famous 'Bees of Malia) pendant is the supreme example of this mastery.

-Niello Technique: The use of black metallic mixture to create striking contracts and decorative designs on gold or silver surfaces, often used to ''paint'' scenes on daggers and precious vessels.

The Smelting Furnace 

Our Knowledge of the ancient Minoan furnace is based primarily on specific findings, most notably at Chrysokamino in Eastern Crete. There, archaeologists discovered remains that allowed us to reconstruct its form.

Based on what we know, the furnace was more like a perforated funnel-a lightweight, conical clay cylinder resembling a chimney, standing about 30 to 50 centimetres tall. The clay helped it withstand high temperatures, while its defining characteristic was the numerous holes across its surface.

The cylinder was placed over a small, clay-lined pit in the ground, where the charcoal and ore were layered. Air entered through the dozens of side holes, creating a simultaneous supply of oxygen throughout the entire mass of charcoal rather than at a single point. This allowed the temperature to rise uniformly and very rapidly to approximately 1,100 Celsius.

Although no intact furnace has been found, its form is supported by substantial evidence. At Crysokamino specifically, over 3,000 fragments of these clay cylinders have been unearthed. Many of these pieces are curved and feature characteristic uniform perforations, indicating they belonged to cylindrical structures.

On many of these fragments, traces of molten metal and slag were found vitrified onto the clay. This proves they were the furnace walls during the smelting of copper. Archaeologists created faithful replicas of these perforated cylinders based on the fragments; during experimental testing, they found that the furnace worked perfectly. As soon as the wind blew, the holes acted as natural bellows, melting the copper in minimal time. 

The fact that no large stone furnaces were found-only thousands of fragments- suggest that they were expendable or designed to be broken after only a few uses.

Metal Recycling

Considering how difficult was for the ancient people to acquire raw materials-since metals were imported from foreign lands and spent days at sea-archaeologists today take it almost for granted that the Minoans followed a recycling system. They would melt down old tools and objects to create new ones. This explains why most of the intact metal objects we find today come almost exclusively from tombs, where they were never recycled.

This is not speculation but a conclusion reached through three main categories of evidence: 

1. Chemical Analysis:

The most powerful evidence comes from analysing the chemical composition of artefacts. Many objects show a mixture of different metal sources. For example, a sword might contain copper from both Cyprus and Laurion simultaneously. This occurred because craftsmen would melt down various objects of different origins together to forge new ones. Frequent remelting also leads to the gradual depletion of certain trace elements, such as arsenic or zinc, which is clearly visible in laboratory analysis.

2. Founder's Hoards:

Archaeological excavations have been brought to light stockpiles of metal that were neither jewelry nor functional items. In settlements like Gournia and Palaiokastro, baskets or vessels were found filled with broken saws, bent knives, and fragments of cauldrons. These finds are known as ''Founder's Hoards''-raw material waiting to enter the kiln to be ''reborn'' as new tools.

3. Distribution Patterns:

Comparing finds from tombs to those from houses reveals a stark difference. In tombs, we find whole objects because they were considered sacred grave goods (ktarismata) and could not be repurposed. In settlements, however, very little metal is found. It appears that even during major, residents took everything with them; even a broken cauldron held immense value as a recyclable scrap. 

4. Oxhide Ingots:

Their economy was deeply rooted in copper. While Minoans used a barter system, they also utilised standardised units of metal for international trade and high-level transactions. These took the form of oxhide ingots-large slabs of copper shaped like a stretched oxhide, weighing approximately 29 kilograms (one talent). When metal travel from so far away, waste is unthinkable. Recycling was not a matter of ecology but of pure savings. It was far cheaper to melt down a broken axe than to purchase new metal newly arrived from the East.

Famous Artifacts

1. The Malia Bess Pendant:

Perhaps the most recognisable specimen of Minoan goldsmithing, discovered at the Phourni cemetery at Malia. It is a masterpiece of granulation, featuring microscopic gold spheres soldered onto the surface. Two bees are depicted holding a honeycomb between them, while golden discs (flouria) hang from their wings and stingers.

2. The Bronze Adorer:

One of the finest examples of the lost-wax casting method. It depicts a man in a prayer stance, with one hand to hos forehead-a typical Minoan salute to the divine. The backward lean of the body captures the physical intensity of worship.

3. The Ritual Double Axe (Labrys):

The Labrys was the sacred symbol of the Minoans. Excavations have yielded everything from massive bronze to tiny golden ones, engraved with intricate patterns. These were not functional weapons but religious objects that adorned palace sanctuaries.

4. The Ring of Minos:

One of the most significant signet rings ever discovered. It depicts an entire religious scene: a deity in a ship, a sacred rock with a tree, and adorers. The level of detail engraved on such a small surface is nearly impossible to conceive.

5. The Dagger with Leopards:

Although found in Mycenae, it is considered a work of Minoan style and craftsmanship. It utilises the niello technique-a black metallic mixture for contrast-on bronze, inlaid with gold. It depicts a hunting scene with the tremendous vitality and fluid movement characteristic of Minoan artistic freedom.
