SCIENTIFIC METHODS FOR ASCERTAINING AUTHENTICITY
 
SPECTROSCOPIC ANALYSIS OF WOOD:

IR Sspectroscopy:

absolute dating of different wooden parts of furniture.
Verifying use of old wood.

IR spectrography:

to identify wood essences.

ATR spectroscopy:

to analyse patinas and veneers.
Example:
Spectroscopic dating analysis of a table (shown in the photo on the left): only the four legs are authentic.

These tests can be requested also by sending directly to our laboratory samples of wood dust taken from the furniture item following the instructions provided in our website: www.SpectroscopyForArt.com.

OTHER TESTS AND EXAMINATIONS:

Use-wear analysis and patina analysis (stereomicroscope, infrared analysis, UV-light and monochromatic light, NeoCell Super C). Identification of construction techniques to verify age. Laquer, glue and pigment analysis (chemical and spectroscopic analysis). Analysis of insect-caused damage.


SOME PRACTICAL TESTS FOR ASCERTAINING AUTHENTICITY:
Genetics Inspection for signs of wear and of the patina
Furniture feet, owing to contact with the floor, show the typical wear due to repeated washing: this authentic and convincing characteristic is known as a "wash patina".  
A natural rub patina is seen to have formed where hands rested on the surface of the wood. Microscopic observation permits the distinction of a natural rub from a mechanical one.

 

Wood's light examinations

Evaluation of glues and their use with Wood's light.

Monochromatic and ultraviolet light show up the quality of and wear to gilding.

 

 

Microscopic analysis of inlaid work: handmade or industrial work?

Decisive for the identification of handmade work are the gaps in the wood and the irregular inlaid pieces typical of handmade work.

 

Inlaid work made by machine in a mould shows pattern edges that fit together perfectly.

 

Examples of spectra in the spectroscopic analysis of samples

These spectra supply an indisputable verdict about the nature of the material. Similar tests can be applied also to identify ivory, horns, bones, old and new amber and plastic.

The Author, Gottfried Matthaes, a physicist, was born in Germany of a family of longstanding artistic tradition and since 1960 has dedicated himself to the study of practical and scientific methods for the ascertainment of authenticity. In 1990 he founded the "Museo d'Arte e Scienza", the only one of its kind in the world, in the centre of Milan where most of the objects illustrated in the handbooks are exhibited, together with its attached laboratory. In 1993 he discovered and patented the application of IR spectroscopy for the age dating of wooden art objects.
