PHYTOLITH, STARCH, PROTEIN RESIDUE (CIEP), ORGANIC RESIDUE (FTIR), AND XRD ANALYSIS OF SAMPLES FROM THE METZ SITE (33ER557) AND THE HECKLEMAN SITE (33ER14), OHIO

Sherds from two ceramic vessels with visible residue from the Metz site (33ER557) were submitted for phytolith, starch, organic residue (FTIR), and x-ray diffraction (XRD) analysis. Two celts were submitted for phytolith, starch, protein residue (CIEP), and FTIR analysis. Phytolith, starch, protein residue, and organic residue analyses were undertaken to better understand what foods may have been prepared or processed using these items. XRD analysis of the exterior slip coating provides information on the composition of this coating material. A second sample, comprising chunks of pigment recovered from a vessel at the Heckleman site (33ER14), was submitted for XRD analysis to better understand the composition of the pigment material.

来自梅茨遗址（33ER557）的两件带有可见残留物的陶瓷容器残片，被送检开展植硅体（phytolith）分析、淀粉粒（starch）分析、傅里叶变换红外光谱（FTIR）有机残留物分析以及X射线衍射（XRD）分析。另有两件石斧（celts）被送检，开展植硅体、淀粉粒、CIEP法蛋白质残留物分析以及FTIR分析。本次通过植硅体、淀粉粒、蛋白质残留物与有机残留物分析，旨在明晰上述器物曾用于制备或加工的食物种类。对器物外部施釉涂层开展XRD分析，以获取该涂层材料的组成信息。另有一份从赫克勒曼遗址（33ER14）的一件容器中提取的颜料块样品，被送检开展XRD分析，以探究该颜料材料的组成成分。
