How exactly does one bright dip sterling??
A very nasty process- an exothermic reaction using industrial
hydrogen peroxide and sodium cyanide. Not a process that you want
to do in the studio- put the sterling pieces (castings) into the
hydrogen peroxide and drop in a couple sodium cyanide eggs and
the (resulting hot!!) solution removes the copper oxides leaving
the sterling shiny. Fume hood, rubber apron, long rubber gloves,
full face protection, you really don't want to do this.
