FURRING is achieved by using a rat tail file sideways. In
this way the file leaves "furry" parallel grooves
in the surface.
Burnishing is an old method of polishing metal. By rubbing
the surface of the metal to be polished with a
highly polished piece of steel called a burnisher,
the surface itself becomes polished.
ANTIQUING is a method of surface colouring, so called
because Silver blackens with age, and in the
presence of sulphur, if it is not polished.
Chemically, tarnishing forms a Silver Sulphide,
and in the case of Sterling Silver, a copper
sulphide as well. Silver Sulphide, can be many
colours, but the most common is dark grey to black
