The National Center for Preservation Technology and Training (NCPTT) and The Center for Historic Architecture and Design (CHAD) in the University of Delaware’s School of Public Policy and Administration are partnering to host a two-day hands-on workshop on the uses of polarized light microscopy for the study of stone and ceramic cultural materials. The workshop will be held March 11-12, 2014 at the NCPTT in Natchitoches, LA.
Polarized light microscopy of stone and ceramics, known as thin-section petrography, is a crucial tool for the study of ancient and historic objects and building materials. The technique is used to identify materials and their possible sources, understand production technology and object functions, study deterioration mechanisms, and assess preservation strategies and conservation treatments. However, specialized expertise is required to use this technique effectively. Preservation professionals, including conservation scientists, conservators, and archeologists, will benefit from this workshop. Students studying or interested in conservation are welcome.
The lead instructor for the workshop is Dr. Chandra L. Reedy, a professor in CHAD and director of the laboratory. The workshop builds on her 2008 book, Thin-Section Petrography of Stone and Ceramic Cultural Materials, with Archetype Publications, London. (The book was the product of a successful Preservation Technology and Training Grant from NCPTT.) The workshop will begin with an introduction to polarized light microscopy as a method for identifying minerals. Subsequent sessions will focus on analysis of cultural materials made of stone (igneous, sedimentary, and metamorphic) and on pottery, terracotta sculptures, bricks, tiles, and clay core materials from bronze castings.
The workshop is open to 20 participants. The cost of the workshop is $299.
If students of the class are interested they can buy Dr. Reedy’s book “Thin-Section Petrography of Stone and Ceramic Cultural Materials” at a reduced fee during registration. The book is not needed for the class only an option.
