content: Raw Material 2: Keokuk/Boone group likely Raw Material Source: Southern Ozarks Luster: Dull Broken: Yes Break Location: Mid Shape/Form: Fusi-elliptical Edge Modification: Bifacial retouching. Alteration: Reconstruction Manufacturing Notes: Thin, bifacially ret blade. Along visible break where glue has given away, there is retouch. It is not a clean break in the chert, but has been worked. The two halves do not really refit. Residue: Prehistoric: glauconite or copper, ocher; Historic: plaster or plastic wood, green pigment, adhesive. Use Trace: Obscured surface makes this difficult to assess. Break surfaces need to be examined for traces of deliberate prehistoric breakage. Comments: Reconstructed using plastic wood or something. This has given way along one break, so that the original chert surface is visible. Entire surface is smeared with reconstructive material, which is included in measurements although I tried to measure on spots where the stone shows through. Added material must be removed in order to assess refitting of blade segments. Chert is homogenous and peppered w/very small dark speckles. Same raw material in both halves. Was examined by conservator N. Firnhaber who removed some of reconstructive material to reveal similar breaks with retouched break edges.
