MEI635: PIGMENTS IDENTIFICATION (FORMERLY COM420)
This course in paint materials identification for conservation professionals in paintings and architecture. The focus of this course is the identification of pigments using polarized-light microscopy (PLM). A practical introduction to PLM methods is taught using many examples from the world of pigments. A more thorough treatment of PLM theory and principles is covered in the INS500: Modern Polarized Light Microscopy course.
This course also introduces students to other analytical methods used as confirmatory methods; these include microchemical methods, elemental characterization using XRF or SEM/EDS, Raman, and infrared spectroscopy. The students examine and sample paintings and architectural artifacts, prepare specimens for analysis, perform PLM analysis, and direct or perform further confirmatory analyses. Methods for characterization of binding media and support canvas materials are also discussed.

- Basic principles of stereomicroscopy including coaxial, oblique, and ring light illumination techniques used for inspection and recording of paint samples. Students use the Olympus SZX10 stereomicroscope.
- Examining and sampling paintings and architectural materials, specimen preparation for PLM, and other analytical techniques.
- Mechanical and optical microscope alignment for optimal illumination considerations and a micrometry exercise. Students use the Olympus BX51 polarized-light microscope.
- Determination of particle morphology, color absorption, and other characteristics.
- The principles of plane-polarized light with hands-on exercises on how to perform refractive index measurements, observations of color, and pleochroism.
- The principles of crossed-polarized light with hands-on exercises determining isotropic vs. anisotropic, birefringence using the Michel-Lévy Interference Color Chart, and qualitative extinction positions of particles.
- Survey of artist's pigments.
- Introduction to canvas fiber analysis.
- Sampling architectural materials.
- Confirmatory methods: microchemical tests, EDS, FTIR, and Raman.
- How to sample paintings and architectural materials
- How to identify artist's pigments
- Polarized light microscopy (Olympus BX51 microscopes and SZX10 stereomicroscopes)
- Canvas fiber analysis
Everyone with the need for problem solving using polarized light microscopy, including:
- Conservators
- Archeologists
- Color Scientists
- Detailed course manual
- Essentials of Polarized Light Microscopy by John Gustav Delly
- Olympus BX51 microscope for each student
- Olympus SZX10 stereomicroscopes for each student
“This was a thoroughly enjoyable course and I am thrilled I could take it. I learned a lot about all the different pigments, papers/fibers and the difference between the many analyses”.
“The various samples/specimens provided at the end of the course allowed us to apply immediately what we learned, and this was a very good way to validate and reinforce the concepts we learned”.
- Familiarity with paints and pigments
- Familiarity with polarized light microscopy concepts is helpful
Students are expected to successfully complete a variety of tasks in the form of hands-on exercises, laboratory exercises, identifications of unknowns, and quizzes. In addition, the students are required to have 100% attendance during the course, participate in class, complete a student evaluation form and pre and post course assessment forms.
The student is notified at the end of the course whether or not they have successfully completed the requirements of the course based on:
- 100% attendance
- class participation
- completion of all course material
- completed and signed student evaluation form
- completed pre and post course assessment forms
Upon successfully meeting these requirements, a student is awarded a certificate of completion and IACET CEU credits, if available. Those who have not successfully passed the course requirements do not receive a certificate or IACET CEU credits.
