Comments: This was not supposed to be sampled; the sample may have been taken from another object and mislabeled.
Technical Observations: The patina is brown with black, green, and red corrosion on the end with the tang. The spearhead is largely intact, although there has been some surface loss and losses along the outer edges. The spearhead was cast and then hot worked. Rough finishing marks on the object could be ancient, but some appear to be from a previous cleaning.
