Extensive Definition
Over the centuries blacksmiths have taken no
little pride in the fact that theirs is one of the few crafts that
allows them to make the tools that are used for their craft. Time
and tradition have provided some fairly standard basic tools which
vary only in detail around the world.
"All a smith needs is something to heat the
metal, [something to hold the hot metal with,] something to hit the
metal on, and something to hit the metal with."
The forge is the fireplace of a blacksmith's
shop. It provides the means to keep the fire contained and
controlled.
Tongs are used to hold the hot metal. They come
in a range of shapes and sizes. Intriguingly, while tongs are
needed for a great deal of blacksmithing, much work can be done by
merely holding the cold end with one's bare hand: steel is a fairly
poor conductor of heat, and orange-hot steel at one end would be
cold to the touch a foot away or so. Trivia: vice-grips were
invented by a smith who wanted a better sort of locking
tongs.
The anvil at its simplest is a large block of
iron or steel. Over time this has been refined to provide a rounded
horn to facilitate drawing and bending, a face for drawing and
upsetting and bending, and one or more holes to hold special tools
(swages or hardies) and facilitate punching. Often the flat surface
of an anvil will be hardened steel, and the body made from tougher
iron.
Blacksmiths' hammers tend to have
one face and a peen. The peen is typically either a ball or a blunt
wedge (cross or straight peen depending on the orientation of the
wedge to the handle) and is used when drawing.
While a great deal of work is done with those
four basic tools, blacksmiths tend to augment their tools with some
of the following (depending on the kinds of work they do):
Swages (hardies) and fullers are shaping tools.
Swages are either stand alone tools or fit the "hardie hole" on the
face of the anvil. The metal is shaped by being driven into the
form of the swage. Opposite to the swage in some respects is the
fuller which may take a number of shapes and is driven into the
metal with a hammer. Swages and fullers are often paired to bring a
piece of metal to shape in a single operation, essentially a set of
dies. A fuller and swage pair might be spoon shaped, for example,
the swage dished to form the bowl and the fuller the convex mirror
of the swage. Together they will quickly stamp a spoon shape on the
end of a bar.
There are many other tools used by smiths, so
many that even a brief description of the types is beyond the scope
of this article and the task is complicated by a variety of names
for the same type of tool. Further complicating the task is that
making tools is inherently part of the smith's craft and many
custom tools are made by individual smiths to suit particular tasks
and the smith's inclination. In the late 1930s Alexander G. Weygers
(a sculptor, painter, and smith} published The Complete Modern
Blacksmith, in which he provided instructions for creating many
useful tools for a blacksmith, which was followed in 1979 by The
Making of Tools.
With that caveat one category of tools should be
mentioned: jigs. A jig is generally a custom built tool, usually
made by the smith, to perform a particular operation for a
particular task or project. For example, a smith making decorative
scrolls for an iron fence will make a bending jig, or scroll iron,
to apply a particular shape to the stock, ensuring that each scroll
has the same bend. (To estimate the length of stock required to
form a scroll of any given size and number of turns the Clackson
scroll formula is used.)
History, Prehistory, Religion, & Mythology
Hephaestus (Latin: Vulcan) was the blacksmith of the gods in Greek and Roman mythology. A supremely skilled artisan whose forge was a volcano, he constructed most of the weapons of the gods, and was himself the god of fire and metalworking.The Anglo-Saxon Wayland
Smith, known in Old Norse as Völundr, is a heroic blacksmith in
Germanic mythology. The Poetic Edda
states that he forged beautiful gold rings with wonderful gems. He
was captured by king Níðuðr,
who cruelly hamstringed him and imprisoned him on an island.
Völundr eventually had his revenge by killing Níðuðr's sons and
forging objects to the king from their skulls, teeth and eyes. He
then seduced the king's daughter and escaped laughing on wings he
himself had forged.
Seppo Ilmarinen, the
Eternal Hammerer, blacksmith and inventor in the Kalevala, is an
archetypal artificer from Finnish
mythology.
Tubal Cain
(not to be confused with Cain, brother of
Abel) is
mentioned in the book of Genesis of the
Old
Testament (the first book of the Torah) as the
original smith.
(Arguably, much of the following information
could or should be placed in the articles on iron, steel, other specific metals, and
metal in general. It is
included here, however, since the development of the metallurgy of iron and steel
is inextricably linked to the history and understanding of
blacksmithing.)
Definition of terms:
- Iron is a naturally occurring metallic element. It is almost never found in its native form (pure iron) in nature. It is usually found as an oxide or sulfide, with many other impurity elements mixed in.
- Wrought Iron is the purest form of iron generally encountered or produced in quantity. It may contain as little as 0.04% Carbon (by weight). From its traditional method of manufacture, wrought iron has a fibrous internal texture. Quality wrought-iron blacksmithing takes the direction of these fibers into account during forging, since the strength of the material is stronger in line with the grain, than across the grain. Most of the remaining impurities from the initial smelting become concentrated in silicate slag trapped between the iron fibers. This slag produces a lucky side effect during forge-welding. When the silicate melts, it makes wrought-iron self-fluxing. The slag becomes a liquid glass that covers the exposed surfaces of the wrought-iron, preventing oxidation which would otherwise interfere with the successful welding process.
- Steel is a mixture of Iron and between 0.3% to 1.7% Carbon by weight. The presence of carbon allows steel to assume one of several different crystalline configurations. Macroscopically, this is seen as the ability to "turn the hardness of a piece of steel on and off" through various processes of heat-treatment. If the concentration of carbon is held constant, this is a reversible process. Steel with a higher carbon percentage may be brought to a higher state of maximum hardness.
- Cast Iron is iron that contains between 2.0% to 6% Carbon by weight. There is so much carbon present, that the hardness cannot be switched off. Hence, cast iron is a brittle metal, which can break like glass. Cast iron cannot be forged.
Steel with below 0.6% Carbon content cannot be
hardened enough to make useful hardened-steel tools. Hence, in what
follows, wrought-iron, low-carbon-steel, and other soft
unhardenable iron varieties will be referred to indiscriminately as
just iron.
Gold, Silver, and Copper may all be
found in nature in their native
states, as reasonably pure metals. It is likely that these were
the first metals to be worked by Humans. These metals
are all quite malleable, and humans' initial
development of hammering
techniques was undoubtedly applied to these metals.
During the Chalcolithic
era and the Bronze Age,
humans in the Mideast learned how
to smelt, melt, cast, rivet, and (to a limited extent)
forge Copper and Bronze. Bronze is an
alloy of Copper and approximately 10% to 20% Tin. Bronze is superior
to just copper, by being harder, being more resistant to corrosion,
and by having a lower melting point (thereby requiring less fuel to
melt and cast). Much of the copper used by the Mediterranean
World came from the island of Cyprus. Most of the
Tin came from the Cornwall region of
the island of Great
Britain, transported by sea-born Phoenician and
Greek
traders.
Copper and Bronze cannot be hardened by
heat-treatment, they can only be hardened by work-hardening. To
accomplish this, a piece of bronze is lightly hammered ad nauseam.
The localized stress-cycling causes the necessary crystalline
changes. The hardened bronze can then be ground to sharpen it to
make edged tools.
Clocksmiths as
recently as the 1800s used work-hardening
techniques to harden the teeth of brass gears and ratchets.
Tapping on just the teeth produced harder teeth, with superior
wear-resistance. By contrast, the rest of the gear was left in a
softer and tougher state, more capable of resisting cracking.
Bronze is sufficiently corrosion resistant, that
artifacts
of bronze may last thousands of years, relatively unscathed.
Because of this, there are frequently more examples of Bronze Age
metal work in museums, than there are from the much younger
Iron
Age. Buried iron artifacts may completely rust away in less than 100 years.
Examples of ancient iron work still extant are very much the
exception to the norm.
Still during the mists of prehistory, humans
became aware of the metal iron, in the form of meteoric
iron. Iron artifacts
may be shown to be of meteoric origin by their chemical
composition: containing up to 40% Nickel. As this
source of this iron is extremely rare and fortuitous, little
development of smithing skills peculiar to iron can be assumed to
have occurred. That we still possess any such artifacts of meteoric
iron may be ascribed to the vagaries of climate, and the increased
corrosion-resistance conferred on iron by the presence of
nickel.
During the (north) Polar Exploration of the early
1900s (AD), Inuit of northern
Greenland
were found to be making iron knives from two particularly large
nickel-iron meteors. One of these meteors was taken to Washington,
D.C., where it was remitted to the custody of the Smithsonian
Institution.
The Hittites of
Anatolia
first discovered or developed the smelting of iron ores around
1500 BC. They seem to have maintained a near monopoly on the
knowledge of iron production for several hundred years, but when
their empire collapsed during the Eastern Mediterranean upheavals
around 1200 BC, the knowledge seems to have escaped in all
directions.
In the Iliad of Homer (describing the
Trojan
War and Bronze Age
Greek and Trojan warriors), most of the armor and weapons (swords and spears) are
stated to have been of bronze. Iron is not unknown, however, as
arrow heads are described
as iron, and a "ball of iron" is listed as a prize awarded for
winning a competition. The events described probably occurred
around 1200 BC, but Homer is thought to have composed this epic
poem around 700 BC; so exactitude must remain suspect.
When historical records resume after the 1200 BC
upheavals and the ensuing Greek Dark
Age, iron work (and presumably blacksmiths) seem to have sprung
like Athena,
fully-grown from the head of Zeus. Very few
artifacts remain, due to loss from corrosion, and re-use of iron as
a valuable commodity. What information exists indicates that all of
the basic operations of blacksmithing were in use as soon as the
Iron Age
reached a particular locality. The scarcity of records and
artifacts, and the rapidity of the switch from Bronze Age to Iron
Age, is a reason to use evidence of bronze smithing to infer about
the early development of blacksmithing.
Despite being subject to rust, iron replaced
bronze as soon as iron-wielding hordes could invade Bronze Age
societies and literally slice through their obsolete bronze
defenses. Iron is a stronger and tougher metal than bronze, and
iron ores are found nearly everywhere. Copper and Tin deposits, by
contrast, are scattered and few, and expensive to exploit.
Iron is different from most other materials
(including bronze), in that it does not immediately go from a solid
to a liquid at its melting
point. H2O is a solid (ice) at -1 C (31 F), and a liquid
(water) at +1 C (33 F). Iron, by contrast, is definitely a solid at
, but over the next it becomes increasingly plastic and more
"taffy-like" as its temperature increases. This extreme temperature
range of variable solidity is the fundamental material property
upon which blacksmithing practice depends.
Another major difference between bronze and iron
fabrication techniques is that bronze can be melted. The melting
point of iron is much higher than that of bronze. In the western
(Europe & the Mideast) tradition, the technology to make fires
hot enough to melt iron did not arise until the 1500s, when
smelting operations grew large enough to require overly large
bellows. These produced blast-furnace temperatures high enough to
melt partially refined ores, resulting in Cast Iron. Thus cast iron
frying pans and cookware did not become possible in Europe until
3000 years after the introduction of iron smelting.
China, in a separate developmental tradition, was
producing cast iron at least 1000 years before this.
Although iron is quite abundant, good quality
steel remained rare and expensive until the industrial developments
of Bessemer et al. in
the 1850s. Close examination of blacksmith-made antique tools
clearly shows where small pieces of steel were forge-welded into
iron to provide the hardened steel cutting edges of tools (notably
in axes, adzes, chisels, etc.). The re-use of quality steel is
another reason for the lack of artifacts.
The Romans (who
ensured that their own weapons were made with good steel) noted (in
the 300s BC) that the Celts of the Po River
Valley had iron, but not good steel. The Romans record that during
battle, their Celtic opponents could only swing their swords two or
three times before having to step on their swords to straighten
them.
On the Indian
subcontinent, Wootz steel was, and
continues to be, produced in small quantities.
During the 1700s, agents for the Sheffield
cutlery industry scoured the
country-side of Britain, offering new carriage springs for old.
Springs must be made of hardened steel. At this time, the processes
by which steel was produced resulted in an extremely variable
product: quality was in no way ensured at the initial point of
sale. Those springs which had survived cracking through hard use
over the rough roads of the time, were proven to be of a better
quality steel. Much of the fame of Sheffield cutlery (knives,
shears, etc.) was due to these extreme lengths that the companies
went to, in order to ensure that high-grade steel was used in their
manufactures.
The original fuel for forge fires was charcoal. Coal did not begin to
replace charcoal until the forests of first Britain (during the
1600s), and then the eastern United States of America (during the
1800s) were largely depleted. Coal can be an inferior fuel for
blacksmithing, because much of the world's coal is contaminated
with Sulfur.
Sulfur contamination of iron and steel make them "red short", so
that at red heat they become "crumbly" instead of "plastic". Coal
sold and purchased for blacksmithing should be largely free of
sulfur.
During the 1900s various gases (natural gas,
acetylene, etc.) have
also come to be used as fuels for blacksmithing. While these are
fine for blacksmithing iron, special care must be taken when using
them to blacksmith steel. Each time a piece of steel is heated,
there is a tendency for the carbon content to leave the steel
(decarburization). This
can leave a piece of steel with an effective layer of unhardenable
iron on its surface. In a traditional charcoal or coal forge, the
fuel is really just carbon. In a properly regulated charcoal/coal
fire, the air in and immediately around the fire should be a
reducing atmosphere. In
this case, and at elevated temperatures, there is a tendency for
vaporized carbon to soak into steel and iron, counteracting or
negating the decarburizing tendency. This is similar to the process
by which a case of steel is developed on a piece of iron in
preparation for case
hardening.
(European) blacksmiths before and through the
mediaeval era spent a great deal of time heating and hammering iron
before forging it into finished articles. Although they were
unaware of the chemical basis, they were aware that the quality of
the iron was thus improved. From a scientific point of view, the
reducing atmosphere of the forge was both removing oxygen (rust), and soaking more
carbon into the iron,
thereby developing increasingly higher grades of steel as the
process was continued.
Prior to the industrial
revolution, a "village smithy" was a staple
of every town. Factories and mass-production reduced the demand for
blacksmith-made tools and hardware.
During the first half of the 1800s, the U.S.
government included in their treaties with many
Native American tribes, that the U.S. would employ blacksmiths
and strikers
at Army
forts, with the expressed
purpose of providing Native Americans with iron tools and repair
services.
Lathes, patterned
largely on their wood-turning
counterparts, had been used by some blacksmiths since the
middle-ages. During the 1790s Henry
Maudslay created the first screw-cutting
lathe, a watershed event that signalled the start of
blacksmiths being replaced by machinists in factories for the hardware
needs of the populace.
Samuel Colt
neither invented nor perfected interchangeable
parts, but his insistence (and other industrialists at this
time) that his firearms
be manufactured with this property, was another step towards the
obsolescence of metal-working artisans and blacksmiths. (See also
Eli
Whitney).
As demand for their products declined, many more
blacksmiths augmented their incomes by taking in work shoeing
horses. A shoer-of-horses
was historically known as a farrier in English. With the
introduction of automobiles, the number of
blacksmiths continued to decrease, many former blacksmiths becoming
the initial generation of automobile mechanics. The nadir of
blacksmithing in the United States was reached during the 1960s,
when most of the former blacksmiths had left the trade, and few if
any new people were entering the trade. By this time, most of the
working blacksmiths were those performing farrier work, so the term
blacksmith was effectively co-opted by the farrier trade.
Starting in the 1970s, trends in "do-it-yourself"
and "self-sufficiency" led to a renewed interest in traditional
blacksmithing. Books and organizations to help beginning
blacksmiths abound, including many re-enactment smiths
demonstrating the art at historical sites. New Hampshire Blacksmith
Joe
Tucker worked as a Blacksmith for more than 75 years, and
helped to popularize the craft among young metalworkers. Many of
the more successful modern blacksmiths produce custom metalwork,
and are referred to a Artist-Blacksmiths.
Artist-Blacksmiths is not merely a modern phenomenon, however: see
Samuel
Yellin.
While developed nations saw a decline and
re-awakening of interest in blacksmithing, in many developing
nations blacksmiths continued doing what blacksmiths have been
doing for 3500 years: making and repairing iron and steel tools and
hardware for people in their local area.
