Petrography has developed into an indispensable tool for ceramic fabric analysis specifically studying the mineralogical and textural composition of ceramic objects.
Although the surface treatment with hf and silane is widely used and accepted for lithium disilicate ceramics 7 12 other alternatives have been proposed to enhance the bond strength between ceramic and.
Ceramic petrography or ceramic petrology is a laboratory based scientific archaeological technique that examines the mineralogical and microstructural composition of ceramics and other inorganic materials under the polarised light microscope in order to interpret aspects of the provenance and technology of artefacts.
The microstructure is the structure level of approximately 0 1 to 100 µm between the minimum wavelength of visible light and the resolution limit of the naked eye.
