Abstract This article discusses fractures and cracks due to ancient artifact weaknesses. It provides several case studies to aid the appreciation of fractography as a diagnostic technique and to understand the importance of cracking. These case histories concern ancient gold and silver alloys, bronzes, and wrought irons. The article considers the applicabilities of fractography, metallography, and chemical analyses in answering archaeological and archaeometallurgical questions. The article also discusses the restoration and conservation of corroded and embrittled artifacts, including the use of coatings.
