Graduate Program in Cultural Resource Management
“how were artifacts made and what were they used for?”
Approaches: • Archaeological • Scientific analysis of objects • Ethnographic • Experimental • Advice of modern experts in
equivalent technologies
“are they artifacts at all?”
Industrial Archaeology
Interpreting the Evidence: Archaeological, Scientific Analysis “how to distinguish?”
Artifacts • shaped by humans • purposely struck off • characteristic bulges/ bulbs of
percussion • regular shape
Nature-forged • shaped by nature/ geologically
processed (heat, frost, fall, etc.) • natural fractures • irregular scars and no bulb • crude shape
Ethnographic Analogy in identifying tools: • people tend to use abundantly available
materials for daily, mundane tasks. • people will invest time and effort into making
implements they will use repeatedly. • can be used in identifying the precise function
of a particular artifact in a specific level. • limited to cultures with a similar subsistence
level and same ecological background.
Interpreting the Evidence: the Use of Ethnographic Analogy
Approaches
Interpreting the Evidence: Experiments
Two classes of raw materials used in creating objects: • unaltered (e.g. flint) • synthetic (e.g. pottery, metal)

• human used stones which found in nature and already had cutting edge for hunting.
• they used tree branches, leaves, and stones to make shelter for living.
• they ate plants and meat, gathered berries. they may have eaten flesh of dead animals left b e h i nd by o t he r l a r ge r predators.
• they used fire by rubbing stones together and roasted meat.
• human started to sharpen their stone tools for hunting.
• they looked for stones (such as flint) that was harder and could be sharpened easily.
• they ate started to settle in one place, but still remain as hunter and gatherer of meat, fish, nuts, fruits, and berries.
• group of hunters learned about agriculture.
• they collected wild crops and domesticated wild animals.
• by 10,000 years ago they started to produce grains, fruits, and vegetables from seeds.
• they made plow out of antlers, stone and wood, and started to cultivate the land with the help of herded animals.
• they used stone mortars and pestles to grind cereals and grains.
How were stone artifacts extracted, transported, manufactured, and used?
UNALTERED MATERIALS: STONE
Extraction Sources most visible archaeologically: mines and quarries. 1. Mines (Neolithic and later flint mines in northern Europe) • The basic technology remained fundamentally the same for the later extraction of other materials. • There are mixture of open-cast and shaft mining, depending on the terrain and seams position. • There were a variety of clues to the mining techniques (i.e. Rijckholt’s antler picks which was effective against
hard rock). • Rock faces were sometimes initially broken up by heating with a small fire. • Some wooden tools have survived at copper mines in the Mitterberg area of the Austrian Alps. 2. Quarries • Unfinished objects or abandoned stones helps archaeologists in making technological reconstruction.

UNALTERED MATERIALS: STONE
Stone Tool Manufacture (smaller stones) • Mostly made by removing material from a pebble or “core” until the desired shape of the core has been
attained. • The core is the main implements, but the flakes themselves can be used as knives, scrapers, etc. • The first recognizable tools are simple choppers and flakes made by knocking pieces off pebbles to obtain
sharp edges.

Some techniques of manufactures can be inferred from traces left on the tools, or observed among the few living peoples who continue to make stone tools, or from artistic depictions. In most other cases, there are two principal approaches in experimental archaeology: 1. Stone Tool Replication • Making exact copies of different types of stone tool – using only the technology available to the original
makers. • To assess the processes entailed, the amount of time and effort needed, much to the benefit of our
knowledge of ancient stone-knapping. • Can be used to discover whether certain flint tools had been heated during manufacture. • To narrow possibilities and points to the most likely method that is being used.
2. Refitting of Stone Tools • Entails attempting to put tools and flakes back together again. • Allows us to follow the stages of the knapper’s craft and movements around the site. • Considerable vertical movement can occur through different layers of site, even where there are no visible
traces of disturbance. • Provides a dynamic perspective on the spatial distribution of tools, and produces a vivid picture of actual
movement and activity in an ancient site.

Technology of the binocular microscope can be used to great effect in the study of engravings on stone: • it can determine the type of tool and stroke
used. • determine the differences in width and in
transverse section of the lines, and sometimes the order in which the lines were made.
• technique of making imprint with plasticine or silicone can shows which lines were engraved after which.
• varnish replicas of engraved surfaces on stones can be examined in the scanning electron microscope, and compared further.

John Coles’ woodworking experiment in the Somerset Levels (England) can be seen in pg. 326-327.
• Have been used to make tools as long as stone and bone, if wood survives in good condition, it may preserve tool marks to show how it was worked.
• Waterlogged wood has yielded the richest information about woodworking skills. (Experiment by John and Bryony Coles, page 326-327).
• Can be categorized into small (tools) and large wooden objects (e.g. buildings, wheeled transportation, and watercrafts).

• Investigating watercrafts: archaeological evidences is abundant in the preserved remains of ships uncovered by underwater archaeology.
• Excavation results showed that vessels of earlier period in the century were built with planks held together by mortise and tenon joints.
• The best way to learn how a ship was built and function is to refit and rebuild the vessel, either a full-size or a scale replica, preferably one that can be tested on the water.
• Archaeology can demonstrate the presence of boats/crafts even where no ship remains or artistic depictions exist.

• Different kinds of fracture, damage, and wear leave diagnostic traces on different classes of fibers.
• Cutting of fibers is easy to identify, and razor-marks are readily distinguishable from those made by shears or scissors.
• Even where textiles do not survive, they sometimes leave an impression behind.
• similarly useful information can be derived from the study of imprints of fabrics, cordage, and basketry that are found on fired clay.

SYNTHETIC MATERIALS
FIRING and PYROTECHNOLOGY
• The whole development of technology –related to synthetic materials- in terms of the control of fire: pyro technology. • The introduction of the potter’s kiln in pottery-making meant higher temperatures could be achieved, also spurring on
the development of metallurgy.
Mesopotamian dome-shaped kiln early 4th millennium BC
Egyptian kiln of c. 3000 BC Greek kiln of c. 500 BC
• Potters’ kiln can control the air-flow and temperatures which lead to metallurgy in Bronze Age and Iron Age. • Technology of the production of glass and faience appeared with the manufacture of bronze –since a higher
temperature and better control are needed.

SYNTHETIC MATERIALS
POTTERY
• The lack of pottery vessels before the Neolithic Period is a consequence of the mobile way of life of Paleolithic hunter-gatherers, for whom heavy containers of fired clay would have been of limited usefulness.
• The introductory of pottery generally seems to coincide with permanent-way-of living, for which durable tools are a necessity.
• Archaeological field –especially Industrial Archaeology- learns a lot from this almost indestructible artifact, starts from the pot tempers, how were they made, how were they fired, and also some evidence from ethnography.
Pot Tempers • The inclusion in the clay –temper- added strength and workability to counteract
any cracking or shringkage during firing. • The finer the temper, the stronger the pot.
How Were Pots Made? • The making or ‘throwing’ of pots on a turntable introduced after 3400 BC.
Previously, pots are made by hand in a series of coils or slabs of clay. • Wheel thrown pots usually have marks left by the fingertips as the potter draws
the outer surface of pots by flat paddles or cloth to paste a smooth finish.
How Were Pots Fired? • The firing technique can be inferred from certain characteristics of the finished
product. (pg. 334-335) • The extent of oxidization in a pot is also indicative of firing methods. (pg. 335)
SYNTHETIC MATERIALS
POTTERY
... How Were Pots Fired? • The archaeology of kiln sites has contributed much to our knowledge of firing
procedures. • The development of kiln in design and construction –from the early, crude, clay
forms to technically advanced brick ones which allow higher firing temperatures- ensure production throughout the year (reflecting the increasing demands being made on pottery-making industry).
Evidence from Ethnography • Pottery making by traditional methods is still widespread in the world, so it is
profitable to pursue ethnoarchaeological studies from the social and commercial points of view.
• Archaeologists can derive many valuable insights fro ethnoarchaeological work. • Historical sources and artistic depictions from a number of cultures provide
supplementary data.

SYNTHETIC MATERIALS
FAIENCE AND GLASS
• The earliest faience (pre-glass) was originated in Predynastic Egypt (before 3000 BC) and used for beads and pendants. • By about 2500 BC, Mesopotamia was making the first beads of real glass, which have been made with the development
of charcoal furnaces for smelting metal. • The first real glass vessels have been found in sites of the Egyptian 18th Dynasty, c. 1500 BC; and the earliest known
glass furnace dating to 1350 BC. • By 700 BC all the principal techniques of making glass had been developed except for glass-blowing –that was finally
achieved in c. 50 BC by the Romans. • Ancient glass is so rare because it is a reusable material (like metals, unlike pottery), with fragments being melted down
and incorporated into new glass. (pg. 336)

ARCHAEOMETALLURGY
Non-Ferrous Metals • The techniques of manufacture of
artifacts made from non-ferrous materials in archaeometallurgy c a n b e i n v e s t i g a t e d i n composit ion approach and metallographic examination. (pg. 337)
• Non-ferrous materials: copper (the most important); tin; bronze; lead; gold; silver; antimony.
• A basic understanding of copper processes is fundamental to any study of early technology.

SYNTHETIC MATERIALS
ARCHAEOMETALLURGY
Alloying • Alloying can have beneficial effects and represents a great step forward in metallurgical practice. (pg. 337) • In investigating early metallurgy, one of the most useful techniques is metallographic examination. (pg. 338)
Casting • This “one-off” method used clay as two-piece mold. When the clay is heated, the melted wax can be poured out; thus the
clay becomes a hollow mold so that molten metal can be poured into it. After the clay casting is broken away, one is left with a metal copy of the original model. (a great example of casting metal objects in ceramic-molds are bronze ritual vessels from Shang dynasty, c. 1500 BC). (pg. 342)
• Molds can yield much useful information, and even the broken clay casings of the lost-wax method have occasionally been preserved.
• Slags studies can also be informative to distinguish copper smelting process from iron production. • Place of manufacture can also be examined to fully understand the technology of piece-molds, clay models, and cores,
i.e. Hou-Ma, Shaanxi Province, China, dating to 500 BC where extraordinary works of craftsmanship were produced by the Chinese this way.
SYNTHETIC MATERIALS
ARCHAEOMETALLURGY
Silver, Lead, and Platinum • Lead is very soft with low melting point so was not used for a wide range of purposes. • Silver are often extracted from lead ores found in nature, this process called cupellation. • Platinum was being worked in Ecuador in the 2nd century BC and being liked for its hardness and resistance to corossion,
and they often used it in combination with gold.
Fine Metalwork • By the late Bronze Age of the Aegean around 1500 BC, various wide techniques in metal working were available for
working with non-ferrous metals. • One method of metal working is plating which bond metals together, e.g. silver with copper, gold with copper, or iron and
steel armor plated in gold that have been invented in late medieval.
Iron and Steel • Known as being used since 1000 BC, there are several techniques in iron-working, such as: smelting iron, cast iron, and
wrought iron. • Steel is simply iron with lower percent of carbon than iron, and both are malleable and capable of hardening by cooling.

REMARKS of Chapter 8: Technology • Stone tools and ceramics dominate the
archaeological record. • Objects made of organic materials rarely survive,
compared with the previous materials. • The introduction of pottery in a culture seems to
coincide with the adoption of a sedentary way of life. • Several approaches that help researchers to
understand how artifacts were made and what they were used for:
Ethnography; Ethnoarchaeology; Experimental Archaeology; Microwear Study.
• A large number od stone tools can be produced while very little raw material is wasted.
• Copper was the most important metal used in early times.
• The alloying of copper to produce bronze represents a significant step forward in metallurgical practice.
