Technique & Production Method describes how an object was made, shaped, assembled, or decorated.
Material tells us what an object is made from.
Technique tells us what was done to that material.
A stone can be carved.
Metal can be cast, forged, or hammered.
Clay can be hand-built or wheel-thrown.
A surface can be engraved, painted, gilded, lacquered, or inlaid.
Understanding production techniques helps reveal the craftsmanship, technological knowledge, tools, and artistic choices behind an object.
Hand-built
Hand-built refers to objects shaped by hand rather than primarily formed on a potter's wheel or industrial machine.
This technique is particularly important in ceramic traditions, where clay may be constructed using hands, coils, slabs, or other manual methods.
Examples include:
hand-built pottery
ceramic vessels
figurines
sculptural forms
traditional clay objects
Hand-building can leave subtle irregularities that preserve evidence of the maker's physical process.
Wheel-thrown
Wheel-thrown refers primarily to ceramic objects formed on a rotating pottery wheel.
The rotation allows the maker to shape clay into relatively symmetrical vessels while controlling their walls, openings, and profiles.
Examples include:
bowls
cups
jars
vases
storage vessels
Wheel-thrown objects may subsequently receive additional decoration or finishing techniques.
Carved
Carved describes material that has been shaped by removing portions of it with cutting or scraping tools.
Carving can be performed on:
wood
stone
bone
ivory
jade
shell
other hard materials
Examples include:
carved sculptures
wooden figures
stone reliefs
jade ornaments
ivory carvings
Carving is fundamentally a subtractive process: the maker creates the final form by removing material.
Cast
Cast refers to objects made by pouring or otherwise introducing a molten or liquid material into a mold, where it takes the desired form as it solidifies.
Casting has been particularly important in metalworking.
Examples include:
bronze sculptures
bronze vessels
metal ornaments
bells
ritual objects
jewelry
One important casting method is lost-wax casting, in which a wax model is used to create a mold before the wax is removed and replaced by molten metal.
Objects such as elaborate ancient bronze artifacts and gold ornaments can demonstrate extremely sophisticated casting knowledge.
Forged
Forged refers to metal shaped through controlled application of heat and mechanical force.
The metal may be hammered, pressed, or otherwise worked while hot or at appropriate temperatures.
Forging has historically been important for:
swords
tools
armor
hardware
metal components
specialized instruments
Forging can produce strong objects and allows the craftsman to control the shape and structure of the metal.
Hammered
Hammered describes material shaped or decorated through repeated blows from a hammer or similar tool.
Hammering is particularly important in metalworking.
It can be used to:
form sheets
raise vessels
create texture
strengthen surfaces
create decorative patterns
Hammered metal may display subtle marks that preserve evidence of the production process.
Hammering can also be combined with other techniques such as engraving or gilding.
Engraved
Engraved describes designs or inscriptions cut into the surface of an object.
The technique can be applied to:
metal
glass
stone
wood
ivory
ceramics
other materials
Examples include:
engraved jewelry
engraved vessels
engraved weapons
engraved glass
engraved inscriptions
Engraving is generally a subtractive decorative process because material is removed from the surface.
Incised
Incised refers to lines, patterns, symbols, or images cut directly into a surface.
Incision is common in:
ceramics
wood
bone
stone
metal
leather
The distinction between engraved and incised can vary according to material and disciplinary terminology.
For this taxonomy, engraved can be used for more specialized or fine surface engraving, while incised can describe simpler or broader cut-line decoration.
Molded
Molded describes an object or component formed by pressing, shaping, or casting material within a mold.
Molding allows repeated or controlled forms to be produced.
Examples include:
molded ceramics
molded glass
molded decorative elements
molded sculpture
molded architectural components
Molding can be used for both functional objects and highly elaborate decorative forms.
Inlaid
Inlaid describes a technique in which one material is inserted into another material to create a decorative or structural surface.
Common inlay materials include:
wood
shell
mother-of-pearl
metal
stone
ivory
jade
Examples include:
furniture with mother-of-pearl inlay
metal-inlaid weapons
stone-inlaid objects
jewelry
decorative boxes
Inlay creates contrast by combining different colors, textures, or materials within a single surface.
Filigree
Filigree is a delicate metalworking technique using fine wires or tiny beads to create intricate openwork patterns.
It is particularly associated with jewelry and decorative metalwork.
Examples include:
earrings
pendants
necklaces
crowns
brooches
ceremonial ornaments
Filigree requires considerable control because the metal elements can be extremely fine.
Cloisonné
Cloisonné is a decorative technique in which small compartments, or cloisons, are created on a surface and filled with materials such as enamel.
Metal wires or partitions define the individual sections.
Examples include:
decorative vessels
jewelry
boxes
plaques
ornaments
Cloisonné is especially associated with East Asian decorative arts, although related techniques have appeared in other artistic traditions.
Enamelled
Enamelled describes an object decorated with enamel, a glass-like material fused to a surface through heating.
Enamel can create intensely colored, durable decorative surfaces.
It can be applied to:
metal
jewelry
vessels
decorative objects
religious objects
architectural elements
Different enamel techniques can produce very different visual effects.
Gilded
Gilded describes an object or surface decorated with a thin layer of gold.
Gilding can be applied to materials such as:
wood
metal
ceramics
sculpture
architectural elements
manuscripts
The gold layer may be extremely thin while dramatically changing the visual appearance of the object.
Gilding has frequently been associated with luxury, religious significance, prestige, and ceremonial display.
Lacquered
Lacquered describes an object coated or decorated with layers of lacquer.
Lacquer can protect a surface while also creating a smooth, durable, and often highly polished finish.
Examples include:
lacquer boxes
furniture
vessels
trays
decorative panels
sculptures
Lacquer traditions can involve multiple layers, polishing, carving, painting, and inlay.
Painted
Painted describes an object decorated with applied pigments or paint.
Painting can be applied to:
ceramics
wood
textiles
metal
stone
plaster
paper
sculpture
Examples include:
painted pottery
painted furniture
painted sculpture
decorative objects
manuscripts
Painting may serve purely decorative purposes or communicate religious, political, symbolic, or narrative imagery.
Printed
Printed describes designs or images transferred onto a surface using a prepared matrix, block, plate, screen, or other printing process.
Printing can be used for:
books
textiles
paper
posters
decorative objects
packaging
manuscripts and printed documents
The technique allows imagery or text to be reproduced rather than individually painted each time.
Transfer-printed
Transfer-printed is a specialized printing technique in which an image is transferred from a prepared surface onto another object.
It became particularly important in ceramics, where printed designs could be transferred onto ceramic vessels and tableware.
Examples include:
printed porcelain
printed earthenware
decorative plates
cups
ceramic tiles
Transfer printing allowed detailed imagery to be reproduced relatively consistently across multiple objects.
Underglaze
Underglaze refers to decoration applied to a ceramic body before the final glaze is fired.
The glaze is subsequently applied over the decoration, protecting the design beneath a glassy surface.
Examples include:
blue-and-white porcelain
decorated ceramic vessels
painted pottery
ceramic tiles
One of the most famous examples is blue-and-white Chinese porcelain decorated with cobalt pigment beneath a transparent glaze.
Overglaze
Overglaze refers to decoration applied on top of an already glazed ceramic surface.
The decorated object is then fired again at an appropriate temperature.
Overglaze techniques allow additional colors and decorative details to be applied after the primary glaze has been established.
Examples include:
painted porcelain
enamel decoration
gilded ceramics
polychrome vessels
Slip-decorated
Slip-decorated describes ceramic decoration made using slip, a liquid mixture of clay and water that can be applied to the surface of a ceramic object.
Slip can be:
painted
poured
trailed
layered
used to create contrasting patterns
Examples include:
decorated pottery
slip-painted vessels
traditional earthenware
patterned ceramic objects
Slip decoration can create both subtle surface variation and highly elaborate designs.
Making vs. Decorating
An important distinction within this taxonomy is between production techniques and decorative techniques.
Production techniques
These primarily determine the object's physical form.
Examples:
Hand-built
Wheel-thrown
Carved
Cast
Forged
Hammered
Molded
Decorative techniques
These primarily modify the object's surface or appearance.
Examples:
Engraved
Incised
Inlaid
Filigree
Cloisonné
Enamelled
Gilded
Lacquered
Painted
Printed
Transfer-printed
Underglaze
Overglaze
Slip-decorated
An object may have several techniques from both groups.
For example:
A bronze vessel
→ Cast
→ Hammered
→ Engraved
→ Gilded
Or:
A ceramic vessel
→ Wheel-thrown
→ Painted
→ Underglaze
Or:
A wooden box
→ Carved
→ Inlaid
→ Lacquered
Multiple Techniques
Historical objects are frequently the result of several successive production stages.
A single object may have been:
shaped,
assembled,
carved,
decorated,
polished,
gilded,
lacquered,
or otherwise finished.
The taxonomy should therefore allow more than one Technique & Production Method where the information is known.
The primary technique should represent the most significant or defining production method, while secondary techniques can be recorded as additional attributes.
Technique and Material
Technique is closely connected to material, but the two categories should remain separate.
For example:
Gold is a material.
Cast is a production technique.
Engraved is a decorative technique.
A gold pendant could therefore be classified as:
Material: Gold
Technique: Cast, Engraved
Likewise:
Material: Ceramic
Technique: Wheel-thrown, Underglaze
And:
Material: Wood
Technique: Carved, Lacquered
This separation makes the collection much more informative.
Technique and Technology
Production techniques provide clues about technological knowledge.
Casting demonstrates knowledge of:
molds
temperature
molten materials
controlled solidification
Forging demonstrates knowledge of:
heat
metalworking
mechanical force
Wheel-throwing demonstrates control of:
clay
rotation
moisture
symmetry
Lacquering demonstrates knowledge of:
surface preparation
resin or lacquer
layering
curing
polishing
Technique is therefore a record of human technological knowledge expressed through craftsmanship.
Technique and Artistic Expression
Techniques do more than construct objects.
They also shape their appearance.
Carving can create depth.
Engraving can produce delicate lines.
Filigree can create openwork.
Gilding can introduce reflective surfaces.
Lacquer can create deep gloss.
Underglaze can produce designs protected beneath a transparent surface.
The technique is therefore part of the object's visual language.
Two objects made from the same material can look completely different because they were produced using different techniques.
Examples from the Collection
Maya K'awiil Eccentric Flint
Material: Stone
Technique: Knapped / flaked
The elaborate eccentric flint demonstrates highly controlled stoneworking. Its unusual silhouette was deliberately shaped rather than being an accidental by-product of ordinary tool production.
Igbo-Ukwu Shell Vessel with Leopard
Material: Bronze
Technique: Cast, likely using lost-wax casting
The intricate form demonstrates sophisticated metal-casting knowledge. Fine surface details and complex shapes could be incorporated into the casting process.
Tairona Gold Figure Pendant
Material: Gold / gold alloy
Technique: Cast, lost-wax casting
The elaborate figure and delicate ornamentation demonstrate the extraordinary control possible through lost-wax metalworking.
Why Technique Matters
An artifact preserves more than its final appearance.
Its surface can contain traces of the process that created it.
Hammer marks.
Carving lines.
Tool impressions.
Casting seams.
Brush strokes.
Engraved grooves.
Layers of lacquer.
Fused enamel.
Inlaid materials.
These traces allow us to look backward from the finished object toward the hands, tools, and knowledge that produced it.
Technique & Production Method tells the story of making.
It asks not simply:
What do we see?
but:
How did someone make this?
That question can transform a beautiful object into evidence of human ingenuity.
How Technique Works in the Collection
The taxonomy can now be understood as a series of complementary questions:
Object Type
→ What is it?
Material
→ What is it made from?
Origin & Cultural Tradition
→ Where does its tradition belong?
Historical Period, Dynasty & Era
→ When does it belong?
Technique & Production Method
→ How was it made or decorated?
Together, these categories turn an object into a multidimensional historical record.
The artifact is no longer simply something to look at.
It becomes evidence of material, place, time, culture, technology, and human craftsmanship.
And behind every finished object is a process.
Technique is the trace of that process.
