The London Artifact is a hammer, probably used for fine metal working judging by its size, weight and the ends of the head. It was found near London, Texas, near a waterfall in 1934. The rock of this area is dated geologically as Cretaceous (144 Million to 65 Million years old), or during the time of the dinosaurs. Besides being a fascinating find, the metallurgy of the hammer is remarkable: Good, high quality metal with no bubbles or slag and a bizarre compounding of 96% iron, 2.6% chlorine and 0.74% sulfur. A cut was made into the corner of the head to verify it was metal. Sixty years later, that cut (shown also on this replica) has still not rusted! When you compound chlorine with iron you get a powder etchant - not tough steel!What is this artifact doing in rock so "old" and how did the people who formed it make it the way they did?
