Extending Experimental Control

Abstract One of the biggest problems faced by archaeologists engaged in flaked stone experiments is that of control. Controls are universally accepted as a way of ensuring reliability of experimental results used to interpret the archaeological record. Here, the use of a new and tightly controllable material in flaked stone experiments is proposed: porcelain. Unlike traditional approaches using stone, porcelain—while demonstrating comparable properties and fracture mechanics—can be more tightly controlled. As such, we suggest that its use ensures greater reliability in results derived from studies of tool manufacture and use and more potential for repeatability of experimental studies. A critique of previous approaches is followed by an assessment of porcelain as a suitable material for experimentation, in which two case studies that piloted the material are discussed. The first demonstrates its use in experiments regarding tool manufacture and skill. The second demonstrates its success in experiments dealing with observations of use-wear, such as projectile point impact fractures. The varied nature of these two studies aptly demonstrates the benefits of using porcelain as a controllable, moldable material.
