Ivory
Elephant tusk or Plastic? 

 

Today it is possible to recognize authentic ivory
very easily

Musical instrument in ivory, Africa

Buddha temple, China (ivory)

Classification of the material

Sometimes, in addition to elephant tusks, the horns of other animals and some kinds of bone are inaccurately included in the category of ivory. Furthermore, increasingly perfect synthetic materials are being produced today which cannot be distinguished from ivory by their appearance alone.

All these materials consist of distinct molecules which can be recognized simply and clearly using spectrographic analysis (see figure right). In order to perform the test, it is sufficient to extract a few milligrams of material (household drill) and mail the sample to a specialized laboratory.

Dating
For authentic ivory it is possible to carry out a test to establish its age, but the procedure is more complicated because in order to take the sample it is necessary to bring or send the object to the Museum’s central laboratory in Milan or to the German branch where it will remain for at most half an hour.
Ivory is characterized by its hardness, compactness, lustre and resilience, characteristics due to its chemical composition. The main element is represented by inorganic substances such as phosphate and calcium fluoride, the age of which is not measurable. But there are also organic substances present which undergo change with the passage of time according to biological laws. Analysis with infrared spectroscopy shows up the molecules present in the material permitting the ivory’s inorganic substances to be clearly distinguished from the organic ones. Analytical dating methods can thus be applied to the latter focusing on selected and measurable molecules.

The application of spectroscopic analysis for the dating of organic materials is patented
(It. Patent Nr. 01266808 - G. Matthaes, 1993)

PRICES: Classification of material: Euro 100 for an analysis. Dating of an ivory object: Euro 150.

ascertaining the authenticity of antique art objects

 

Over 2,000 items are on display in the Museum's 18 rooms covering the main sectors of antiques.
A modern scientific laboratory as well as
interactive test stations are at the disposal of visitors.

 

test station room 8:
sniff test on excavated pottery

test station room 9:
test for revealing use of plastic

identification of glues and other synthetic materials with Wood’s light

test station room 9: examination with a magnifying glass of signs of wear and decorations on china

 

 

optical examination of signs of wear to identify an authentic piece of silverware

shadows reveal the industrial or handcrafted manufacture of glass

the microscope distinguishes authentic patinas and encrustations from faked ones

the dull sound of a porcelain item reveals hidden restoration work

A scientific laboratory at the service of art

The Museum laboratory’s mission is to improve existing scientific methods and elaborate new methods for the ascertainment of the authenticity of art objects. The laboratory’s instruments and know-how for the determining of authenticity are at the disposal of collectors, art experts, restorers, art galleries and museums.
(The staff of the laboratory, who speak the main European languages, are at your disposal for any explanations).
 

The laboratory of the Museo d'Arte e Scienza is a non-profit facility
and is independent from every point of view.

 

Tests carried out by the laboratory:

Spectroscopic dating and characterization of wooden objects

Microscopic tests on paintings, antique bronzes, excavated pottery, etc.

Examination of underlying layers using infrared reflectography

Analyses of paint layers with a duroflexometer

Analyses with Wood’s light, UV and IR

 

FURTHER ANALYSES PERFORMED IN THE LABORATORY:
Spectroscopic chemical analyses on pigments, glues, encrustations, patinas, products of corrosion. Scientific, practical and instrumental tests of authenticity on: ivory, amber, archaeological glass, pigments, metals, stones, carpets, tapestry, prints, books, clocks and watches, china.
