Thin-section petrography is used to characterize and interpret stone and ceramic cultural materials. Information is obtained regarding choices in raw materials, possible location of material sources, fabrication methods, firing conditions, decorative techniques, possible functions of the object, technological style of the craftsperson or workshop, state of deterioration and possible deterioration mechanisms, and results of testing various preservation approaches. The Laboratory for Analysis of Cultural Materials specializes in working with contemporary methods of digital image analysis to produce quantitative data and enhanced qualitative data from thin-section petrography.
The book, Thin-Section Petrography of Stone and Ceramic Cultural Materials by Chandra L. Reedy, 2008, is available from Archetype Publications, London or

A webinar was recorded with the National Center for Preservation Technology and Training. The topic is an introduction to scientific method, research design, and experimental design for preservation and conservation research. The webinar is organized into four parts: I. Scientific Method, II. Basic Concepts of Experimental Design, III. Multiple Object Designs, and IV. Single Object Studies and Design Variations. The entire webinar can be viewed from the link below. At that link, scroll past the video presentation to find a written script for the webinar. Below that are links to the PowerPoints, to handouts of practice exercises, and all references discussed in the webinar.
