    Fabulous. The SCARF link is really interesting with great pics, thanks for including that – we’ve some lovely jet and amber from the period in the Wiltshire Museum in Devizes of course, but really good to see the amazing Scottish material. One question – was the tin really cast into the channels cut in the jet? I would have thought tin soft enough to impress into the spaces (you can bend whole ingots in your hands), and I’m not sure if the jet (fossilized wood, after all) could have borne the heat?

      Hi Katy. The idea of the tin being cast into the channels in the jet came from the site report:

      http://repository.nms.ac.uk/448/1/133_0004_1.pdf

      It has this to say:

      “How was the tin inlaid? The presence of traces of tin in the shallow incisions as well as in the grooves suggests that it may have been applied in molten form (rather than as a wire or foil ), with excess wiped off the button’s surface. Furthermore, the shape of the grooves supports this idea: had wire been used, then theoretically a groove shaped like an inverted V would have been required to keep it in place after inlaying. Pure metallic tin (as in this case) melts at the low temperature of 232°C, and therefore in theory it should not have damaged the surface of the jet, which would have been polished all over prior to the decoration.”
