When looking at the crust of the Famenin hammer one of the first things that you notice is that there appear to be little flakes of shiny metal on some of the pieces. Poke and prod at them a bit and you soon realize that they’re only lightly stuck to the surface. At first, I thought that they were somehow bits of the aluminum foil that they were wrapped in. But then, after thinking about it, I realized that they’re actually bits of the roofing material that stuck to the stone on impact. Look a bit closer and you also see ‘fuzzy stuff’ (yes, a technical term) that is apparently also from the roofing material. Very cool!
