How can I keep the patina on my jewellery?

Anything you put on top of a patina in order to preserve it will
change the way the light reflects off the silver. So it's a bit of a
tradeoff. Some people don't like the change in reflectivity, others
don't mind at all.

If the patina is only in recessed areas, you should be able to rub the
surface of the silver lightly with a jewelry polishing cloth without
removing the patina in the recessed areas if you are careful. If it's
on the surface of the piece, the patina will change over time if you
don't coat it. (Patina is essentially a controlled form of tarnish, so
by definition any patina is at a particular point in its evolutionary
cycle, so to speak, at the time you apply it.) Protecting it against
light, moisture, salt, and both acid and alkali, including
perspiration, will help preserve the color longer.

Some people swear by Nikolas 2105 Spray Lacquer in Clear, which is
available online from Votaw Tool Company (www.votawtool.com).

What is PMC?
Precious Metal Clay (PMC) consists of microscopic particles of silver or gold suspended in an organic binder to create a pliable material with a consistency similar to modeling clay. PMC can be worked in the fingers and with simple tools to create a vast range of forms and surfaces unobtainable or laborious with traditional metalwork techniques. When it is heated to a high temperature, the binder burns away and the metal particles fuse to form solid metal that can be sanded, soldered, colored and polished like conventional material.    From the Mitsubishi Materials website...

What are the problems associated with quenching hot metal clay?
If you want to refire, enamel or solder on a piece of metal clay that has been quenched, you may find that moisture has got trapped in the metal. When you heat it again, especially if you heat it fast, the moisture turns to steam and may cause a blister on the surface. You need to dry the piece thoroughly if you have quenched the metal following the initial firing.It is also important to remember that you should not quench a piece which has glass or stones as part of the design. The sudden change in temperature from the firing to the cold water may cause shock and the stone or glass could be damaged or break entirely. Leave your piece to air cool, it should only take a few minutes....
