This book is for students and practitioners of not only knapping, lithic technology and archaeology, but also of fractography and fracture mechanics. At conferences on fractography of glasses and ceramics, the author has often been asked to demonstrate knapping as well as provide overviews of fractography learned from it. The first part of the book is intended to stimulate such interests further, in order to solicit contributions from a largely untapped pool of experts. Such contributions can advance significantly our understandings of knapping as well as fractography. In Part II of the book, fracture markings as the tools of fractography are introduced, with their formation, meaning and utility explained. Observations on the presence or absence of the markings in knapping are considered in Part III, along with a number of interpretations of fracture features. The basic principles and concepts of fracture mechanics and fractography apply to fractures produced in any cultural context. This volume therefore addresses most questions on fracture in a generic sense, independent of cultural contexts. In general, understanding of fractures provides a sounder basis for lithic analysis, and use of more recent scientific tools opens new avenues for lithic studies.
