KNOWLEDGE BASE – RECOGNIZING ANTIQUES

Materials, Techniques & Age Characteristics

Identifying antiques is a combination of knowledge, observation, and experience. Many objects appear old at first glance, but were later crafted in a historical style. By paying attention to materials, construction, details, and signs of wear, you can better determine whether an object is authentically antique and from which period it originates.

This guide provides an overview of the most important features.

1. Materials and their age characteristics

Wood

• Genuine antique: irregular hand-carved details, natural shrinkage and cracks, oxidation on nails or screws.

• Reproductions: machine-cut ornaments, even patterns, modern screws.

Ceramics & pottery

• crackle that has been created by hand in the glaze

• irregular glaze layer

• hand-turned shapes (slightly asymmetrical)

• traces of age on the bottom

Metal

• oxidation (e.g. copper oxide, tin pestle, bronze discoloration)

• wear in natural places (handle, lid, edges)

• casting seams in older casting techniques

Glass

• bubbles or irregularities in mouth-blown glass

• sharp shapes in pressed glass from around 1890

• wear on the bottom due to years of use

2. Construction & techniques

Handwork vs. machine work

Objects made before about 1850 are usually completely handmade.
Features:

• variation in details

• visible tool marks

• small imperfections

After 1850, techniques became more mechanical.
Features:

• tighter symmetry

• uniform patterns

• modern fastening materials

Connection methods

• Wood: wooden pegs, dovetail joints, hand-forged nails

• Metal objects: soldering, casting seams, early welding techniques

• Ceramics: hand-turned ring lines, traces of handles or ears

3. Finish and patina

Original patina

• caused by oxidation, light, touch and use

• not to be confused with artificial aging

• feels natural and uneven

Color change

• dark edges, wear on corners

• discoloration by light and air

Traces of use

• small scratches in logical places (for example on handles)

• wear on the bottom due to prolonged contact

4. Typical indicators of old age

1. Assymetry

Handmade objects are rarely perfectly symmetrical.

2. Irregular enamel

In older techniques, the glaze is thicker, more uneven and sometimes drippy.

3. Traditional typography

In cans, books and labels you can often recognise them by the old-fashioned fonts and language used.

4. Smell

With old books, wood or textiles, odor can be an indication of decay, moisture or long use.

5. Valuation: What makes antiques valuable?

1. Authenticity

Objects with original parts and original finishes are more valuable.

2. Rarity

Unique shapes, limited editions or typical regional variants.

3. State

Chips, cracks, dents or repairs affect the value, but authentic patina often increases it.

4. Provenance

Objects with clear provenance, markings or historical background have additional collector's value.

6. Common pitfalls

• “Antique look” that has been artificially applied

• Reproductions from around 1970–1990 that appear outdated

• Modern screws or industrial welds

• Faux patina due to chemical treatments

Why this knowledge is useful

• better buying and selling

• better valuation

• preventing bad purchases

• recognizing quality

• appreciating crafts and history
