Dear Patrice
We get a thick scale development on our workpieces during experimental brazing. The
copper alloy that has flowed over the surface of the iron is concealed by scale that we have
taken off using a pickle to reveal the coating. I haven't looked at the scale yet to see what
textures it possesses.
For the objects covered in scale see http://www.geoarch.co.uk/experimental/bell.html
particularly the images associated with the entries for 5/12/07 and 12/12/07.
Best wishes
Tim
