by gold scrappers to gage plating thickness. There is a
direct relationship between rubs with a Pink Pearl eraser
needed to remove the gold plating down to the base metal,
and the thickness of the gold in microinches.
I remember reading this rule when I was a kid, working as
a silver plater.

Would a typing eraser work ?
I didn't want to just try anything, who knows it could be silver plated. If a
typing eraser will do the trick I'll find one. Years ago I wouldn't be caught dead
without one. I also cut them with a knife sometimes at an angle so that it has
support, at least going one way. There should be no problem carving it into the
proper shape or this.
