    It is how it used to be tested at Edinburgh Assay Office back in the day. They took such dreadful scrapes from every surface that it was common practice not to send in anything finished and more often no more than soldered but pickled sometimes even with all the component parts. Sometimes it was difficult to recover the scraped areas
