Archaeochemistry is the use of analytical chemistry to verify and, in some cases, inform the social science analyses of material remains in archaeology. For this poster, the methodology and results of two different undergraduate research projects in the area of archaeochemistry are presented. In the first project, the powdered ceramic matrix from a potsherd (radiocarbon dated to 586-762AD) was analyzed using gas chromatography-mass spectrometry. The data indicate the original ceramic vessel was dedicated for medicinal use. The interpretation and implications of this result will be discussed. For the second research project, inductively coupled plasma-mass spectrometry (ICP-MS) was used to evaluate the accuracy of ethnographic and historical accounts of two 19th century West Virginia mummies. Specifically, the authenticity of the original patent for the embalming solution used by Graham Hamrick was assessed by comparing the patented “recipe” to the results of ICP-MS analyses performed on samples of the solution. Both studies demonstrate the usefulness of chemical analyses in further informing archaeological records.
