Subject: Workshop on pigment identification
The College of Microscopy is pleased to offer a Special Applications course in paint materials identification for conservation professionals in paintings and architecture, COM420: Microscopical Identification of Pigments for Art Conservation and Architectural Restoration Professionals 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 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, XRD, 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. Course Outline Basic principles of stereomicroscopy including coaxial, oblique, and ring light illumination techniques used for inspection and recording of paint samples. Students will use the Olympus SZX12 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 will 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-Levy 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 What You Will Learn: How to sample paintings and architectural materials How to identify artist's pigments Polarized light microscopy (Olympus BX51 microscopes and SZX12 stereomicroscopes) Canvas fiber analysis Who Should Enroll: Everyone with the need for problem solving using polarized light microscopy, including: Conservators, Archeologists, Color Scientists Student Learning Resources: Detailed course manual including John Gustav Delly's new book, Essentials of Polarized Light Microscopy Olympus BX51 microscope for each student Olympus SZX12 stereomicroscopes for each student Suggested Prerequisites: Familiarity with paints and pigments Familiarity with polarized light microscopy concepts is helpful Satisfactory Completion Requirements: Students are expected to successfully complete a variety of tasks related to the material presented in the course. These tasks will be 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, and complete a student evaluation form.
