To understand a work of art or archaeological cultural relics, it is necessary to study from all aspects.
Mastering its structure and chemical composition can help researchers trace the production process and raw materials of cultural relics, and provide ideas for the protection and restoration of cultural relics
.
Non-destructive testing by scanning electron microscopy can provide help for the study of the microscopic morphology and chemical composition of cultural relics
.
1.
Craft research on ancient utensils
Using scanning electron microscopes, the size and combination of grains in ancient pottery and the shape distribution of internal pores can be studied, the degree of vitrification of pottery can be observed, and the firing temperature can be analyzed.
In addition, as follows As shown in the case, the chemical composition of the pottery can also be obtained by energy spectrum analysis, and the approximate manufacturing process of the pottery in this era can be inferred from this

EDS Composition Analysis of Pottery
For ironware, the composition, distribution, quantity, phase structure, etc.
of the inclusions contained in it can be analyzed to deduce its production process level
.
As shown in the following case, the SEM morphology analysis and EDS elemental analysis of iron utensils can be used to obtain the type, size and distribution of inclusions in iron utensils, so as to have a general understanding of the production technology level of iron utensils in this era.

Identification
of Objects Objects can be identified to a certain extent with the help of EDS compositional analysis capabilities
.
The above case shows a white powder, which is an ancient female cosmetic product.
It shows a layered structure when observed under a scanning electron microscope.

Non-destructive testing
of cultural relics For cultural relic protection workers, the integrity protection of cultural relics is as important as the detection of cultural relics
.
As a common nondestructive testing method, SEM can be used in the surface analysis and composition analysis of cultural relics
.
The Phenom XL G2 Okura-style benchtop SEM can provide a larger sample chamber, combined with the fully automatic mosaic (AIM) function to non-destructively obtain comprehensive topographic characterization of cultural heritage samples
.
The SEM image of the sample obtained by the panorama puzzle function has a field size of 17.
