This virtual seminar on Zoom introduces the techniques involved in identifying pigments visually with the aid of a polarising light microscope. The different optical properties of pigments observable with the microscope will be described and demonstrated and methods by which the observed properties can then be used (either directly or from microscopic samples) to identify pigments found on decorative surfaces will be discussed.
Instrumental methods of identifying pigments will be presented in an IAP virtual seminar on March 6th.
