Caring for copper,

Objects made of copper,
brass and. bronze need little
care, as they keep well in the
average room — not too hot
or too cold, not too dry, or
. too damp.

However, they should be
prevented from coming into
contact with iron, since this
may result in a chemical
interaction, producing
unsightly spots that are
difficult to remove. or. tur-
ning the whole object an
unattractive color.

Articles made of copper
or of copper alloys may be
covered with a layer of
corrosion caused either by
carbon or water or by a
number of other substances,
some of which can have a
serious effect. O

Using a strong magnifying
glass, it is easy to distinguish
between _these | different

es of corrosion because -

their effects are completely
different. So

by the atmosphere is not so
bad as that caused by soil. In
the first case, the surface
may be coated with an
authentic patina which will
enhance rather than detract
from the object’s beauty,
whereas in the latter, it may
be covered with a layer of
grime or even with a thick
crust which corrodes the
metal. ;

Objects coated with a.
genuine -patina should be

cleaned very carefully in

. order to retain it. The patina

may be a brilliant green or a
deep blue or brown and
often is as smooth as glass.

' Ordinary dirt may be
removed with a soft brush
under running water, though
more obstinate particles. will
have to be removed with
greater force using a
thumbnail or a dull blade.
The article should then be
thoroughly washed in
distilied water, changing the

water several times if
possible, and dried with a
hairdryer or fan.

When the item is com-
pletely dry and has returned
to room temperature, it may
be coated with a layer of
transparent lacquer.

A mid-19th century recipe
called for “Shellac, gam-
boge, dragon’s blood, each

four parts, saffron one part,

rectified spirits 25 parts;
digest with heat and strain.”
However, a modern com-
mercial product will seal the
surface just as well!

Should the lacquer create
a harsh glitter that spoils the
effect of the patina, the
surface may be painted with
a solution of wax and carbon-
tetrachloride. , -

No special precautions are
required for cleaning pieces
covered with grime, but the
grime should be removed
quickly before severe

corrosion has a chance to
occur.. Use of a standard
liquid cleaner or special
paste should be sufficient.

Pieces which are in
particular danger from their
environment may be given a
film of transparent lacquer
for protection.

Finally, objects which are
very old, which often have
been buried, may be heavily
corroded, their blackened
surfaces appearing | en-
crusted and uneven. Their
care is best left to properly

trained and . experienced .

experts .who can ~ use
chemical and_ electro-
chemical methods to restore

‘them.

Gourmet sets record

Everyone knows. those
C.B.ets love the sound of

their. own voices and their

own peculiar language. But
over in Vancouver there's
one guy who can out-talk the
best of them on the air.

The Galloping Gourmet, —

as he’s known to his C.B.
brothers, has been yacking
away non-stop for more than
a week now and as the clock
passes.
(Sunday) it will all have been
worthwhile for him.

For, at that time, he'll be -

the.new record holder for
C.B. talking as he passes the
250 hour mark and his name
can be entered in the
Guinness Book of Records. |
