Sealing copper and silver


#1

…I’ve searched and searched again…but can’t find the few
postings that deal with better alternatives to Rennaisance Wax to
’seal’ copper bracelets and patina-ed metals. (I understand that
Rennaisance Wax doesn’t ‘wear’ well and could cause skin
irritations.)

…something rings a bell… “protecta-coat”… “clearcoat”…
I’ve tried every combination of spellings and can’t seem to find
anything.

Alas, I’m in Canada…we don’t seem to have the ‘goodies’ Americans
have.

…or do I just use Krylon spray?

cheers, and thanks for any help you can offer.

Hi Audrey… I’ve tried several types of coatings until finally
deciding on " Permalac " . Check out their website

Par 15 makes a catalyzed clear coat used on cars and marine bright
work. It gets harder upon exposure to water. It is expensive but it
is one of the toughest coatings I have ever had to try and remove…
I goofed and had to remove “it” to do some further work on a gate.
Tough, tough, tough…

I went to a two week school in Florence Italy called Alchimia. They
told me to use the spray meant for cars. I have been using Dupli
Color, Perfect Match. Protective Clear Coat Finish. You guys
probably have some good clear coat for cars because of the snow. I
get mine at O’Riellys (may be spelled wrong). You MUST it outside. A
few very light coats better than heavy. I like the way it brings out
the color in copper with that rich fire patina. You can check my web
site, most of the copper on the site has had this spray.

Hi Audrey,

I think the material you’re looking for is Protect A Clear by
Everbrite http://www.ganoksin.com/gnkurl/ep7zg5

I was interested enough to order some of this but have not received
it yet so I can’t comment on its usefulness. I, too am in Canada but
the company claims to be sending the material to Canada regularly.

The Orchid discussion it was mentioned in was actually about the use
of Renaissance Wax, so you could use that for your search.

Audrey,

I’ve heard about using Krylon spray. Haven’t tried it. I’ve seen some
posts on Ganoksin suggesting the same clear lacquer used for
automobiles. Logic being that if this lacquer can last through road
dings, it might stand up to jewelry wear.

I’ve found a website recommending a product called ProtectaClear
from Everbrite.

http://www.ganoksin.com/gnkurl/ep7zg6

The jewelry artist who recommends this is Jade Orchid. Here is her
blog, called “A Work in Progress:”

http://www.ganoksin.com/gnkurl/ep7zg7

If you scan down the posts in her blog, you’ll find two relevant
posts. The first is June 6th - click on this link, and at the bottom
of the page she has a detailed tutorial about using ProtectaClear
which can be downloaded as a PDF. On June 16, just above the June 6
post, she has an additional PDF about using ProtectaClear to protect
chain.

The staff at Everbrite are very willing to answer questions. The
jeweler, Jade Artist, may also be willing to comment about her
experiences in using ProtectaClear.

The comments I’ve read about using any kind of lacquer generally
include the statement that eventually, somehow, jewelry will get
dinged hard enough to chip even the hardest lacquer. At that dinged
place, tarnish starts to form. The customer might get unhappy enough
with the spot(s) of tarnish to bring the work back to the jeweler.
The jeweler then has the joyous task of removing all the lacquer
without damaging patina or stones, cleaning up the tarnished area,
then presumably sealing the work again.

It may be well nigh onto impossible to remove a permanent lacquer
without also causing changes to any original patina in the work.

So far, I’ve been giving my customers a section of Sunshine cloth
and telling them that jewelry subject to tarnish should be stored in
a clear plastic bag to slow down the tarnishing process.

I have an ionic cleaner from Speedbrite. This uses chemicals which
are safe even for pearls. I haven’t tried turquoise or jade in the
cleaner yet; you can ask the company about the cleaner’s ability to
work with these stones.

This cleaner has been a godsend for me. I just put several pairs of
earrings, or one bracelet or necklace, at a time in the cleaner;
turn it on for 10-20 seconds; and the silver comes out clean. Copper
also comes out bright and shiny. notice: any patina on the metal goes
away (use sunshine cloth on patina’ed metals). I use this cleaner
when I’m getting ready for shows, or when my own jewelry starts to
show tarnish.

Hope this helps.

You can try permalac at
http://www.ganoksin.com/gnkurl/ep7zg9

wow!..thanks everyone! I leapt. Looked up Permalac (eek.
California)…but found it sold through an Ontario Sculpture Supply
House in ‘my backyard’. Added benefit of this thread: your generous
replies led me to some fabulous links!

All appreciated.
Audrey.

I just taught a class over in Brevard county Fl. One of my students
is an Ex NASA employee. She ordered the everbrite product. On the web
site they do not put the MSSDS sheet info. When she got it, some of
her former collegues looked at and said, DO NOT use it" When going
back to their website I read further about coating copper pots. They
said the pots were more for decrotive use and should not be used
much. Another red flag. Long story short she sent it back after
talking to their service rep. Jewelry use is iffy, due to the
allergic reactions most people have to it.

To coat copper I can give a history lesson of sorts. In Renaissance
time, they used bees wax. That didn’t last long, but they had plenty
of people to do the menial work of upkeep for them. Once lacquers
were more available they were used, but flaked off. There have been
various products that have come and gone. Since I make thousands of
copper hand forged Christmas ornaments to old ways, I always seek a
new way to protect the ornaments. I’m intrigued by the POR 15 stuff.
I plan on getting some unless others have had more experience and
want to share.

I use a product from Rio Grande. Klair coat ceramic electroplating
coating. It puts a clear nano ceramic coating on the items and is
hypo allergenic after it is plated and cured… also prevents
oxidation on all metals… you might want to try it…

Cool. thanks!

I just checked it out (it’s Kliar…) and may be a little much for
my ‘micro-business’…looks very interesting, though. I’m giving
Permalac a shot…seems ok so far.

cheers,
Audrey
