<p>[QUOTE=&quot;Bakersgma, post: 4564693, member: 59&quot;]Just to forestall a misunderstanding - Sheffield Plate is created by a mechanical process, whereas 20th century &quot;silver over copper&quot; is an electroplating process. SP involved pressing a sheet of silver and a sheet of copper together by &quot;rolling&quot;&nbsp; (imagining doing this with a modern pasta maker.) In this process there is no &quot;white metal&quot; base for making items.&nbsp; </p><p><br /></p><p>From about the mid-1800s the electroplating process became widely available to make items more quickly and less expensively. Plating the base metal with copper first produced a more durable surface upon which to apply the silver plating layer and manufacturers began making customers aware of this advantage by labeling items with &quot;silver over copper.&quot; Mostly seen on US items in the mid-20th century. I don&#039;t know whether this was the case in Australia.[/QUOTE]</p><p><br /></p>
