Date: Monday, February 3, 2014
The National Center for Preservation Technology and Training (NCPTT)
and The Hooke College of Applied Science with the McCrone Group,
Inc.  are partnering to host a three-day hands-on workshop on
Pigment Identification and Analysis for fine art and architectural
finishes. The workshop will be held February 25-27, 2014 at the
NCPTT in Natchitoches, LA.  This workshop is only open to 20
participants, so please register early to reserve your spot. Tuition

He mentored under the tutelage of Dr. Walter C. McCrone where he
learned the special skills necessary to examine and analyze the
materials constituting works of art, historical objects, and
documents, both historical and contemporary.  His analytical duties
include the analysis of art objects such as paintings and prints,
ancient documents and historical and archeological artifacts using a
variety of analytical tools including polarized light microscopy,
SEM with x-ray spectrometry, infrared and Raman spectroscopy and
others analytical modalities as appropriate.  Forensic document
examinations including forged and altered documents; paper, ink and
toner comparisons; writing sequence determinations and printing
process identification.  His scientific imaging specialties include
photomacro- and -micrography and invisible radiation photography.

Topics covered in the workshop will include polarized light
microscopy and pigment identification as relevant to cultural

    Introduction to microscope basics: nomenclature and mechanics

    Microscope basics: Koehler illumination; micrometry

    Polarized light microscopy

    Introduction to pigment identification

    Examination, sampling, and documentation of pigments
