This chapter summarizes the history, theory and methodology of ceramic X-radiography. Particular emphasis is placed upon the two most common uses of ceramic X-radiography, namely the identification of forming techniques and the characterization of clay fabrics. Practical considerations are offered for the choice of X-ray set-ups, exposure parameters, digitization, image enhancement, analysis and interpretation of the resulting X-ray. The chapter concludes with three case studies that demonstrate the great value of this technique and its potential to help illuminate many socio-cultural dimensions of ancient pottery production. The authors emphasize that deep understanding of the theoretical and practical dimensions of this technique are an essential foundation for subsequent interpretation.
