The experimental replication of lithic artifacts occasionally encounters issues of standardization and control. Two major issues are how to accurately create a large sample population and how to sample from specific stages over the flaking process. Knappable stone is unpredictable due to inclusions, cracks, and differences in size, texture, and fracture toughness. While this aspect of stone is critical to understanding some aspects of human behavior, decision-making, and skill assessment, in some experimental studies it may hinder other areas. Research for a large study assessing the failure of Folsom preforms during the fluting stage required many knappable facsimiles. The process outlined here uses porcelain as a medium for tackling these requirements. The new method presented here illustrates how a 3-D scanner and printer can be used to record and produce a copy of the artifact form. It then describes how to create a plaster mold of the printed artifact form and, finally, how to cast and fire the artifact replica in porcelain.

These techniques are compared and contrasted to determine the composition of intra-formation Edwards Plateau chert. As a case study, three unique chert outcrops only several hundred meters apart (hyper-local (Speer 2014)) at the Gault Site (41BL323) in central Texas were tested with each of the techniques. The differences of each instrumental technique on Edwards Plateau chert is assessed using the geochemical data retrieved. The geochemical data were evaluated with multivariate statistics in order to determine which instrumental technique is most effective at distinguishing between these three unique Edwards Plateau chert outcrops. This study also seeks to determine if either of the instrumental techniques can effectively separate out geochemical differences of Edwards Plateau chert outcrops.
