How do I remove Liver of Sulphur patina from specific areas of my work only?

One of the easiest ways to remove patina from specific areas is to use polishing papers - I like to use the blue one. You could also use a very fine salon board to remove the patina from the 'high' areas.

Use a burnisher - steel or agate - to shine up hard edges.

Linda Kaye Moses has this tip:-

If you want your entire piece to be given a patina, but don't want it to be black, here's a solution (no pun intended). Dip the entire piece in the LOS solution and allow it to become flat black/grey.

Dip a 100% tightly woven cotton cloth in a little olive or canola or corn oil ( a little goes a long way). Old cotton dress gloves work beautifully, because you can slip one hand in one and dip an index finger in the oil.

Next touch the oiled area on fine grit (extra fine grit is even better) pumice. You can get this from woodworking suppliers. You only need a little on the tip of the glove finger or on the cloth.

Wipe this across the surface of your piece, removing the darkened patina on the surface only. You may need to re-pumice/re-oil clean areas on the glove/cloth. This will leave the dark patina in the letters or in any recessed areas.

Wash the piece in warm water with a mild detergent.

Wipe the surface with a Sunshine Cloth (or an equivalent polishing cloth) for a bright surface on the piece.

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 is the process for firing Copper clay with Dichroic glass?
The original copper clay (Copprclay or Hadar's clay) that needs to be fired in carbon can't really be combined with glass in one firing. The glass would pick up the carbon during firing . You could design something that allowed you to connect the glass element after the initial firing, like a traditional prong setting.  There are several reasons why Art Clay Copper Clay or Hadar\'s Quick Fire Copper Clay won\'t work with glass. It needs to be fired at a high temperature so the glass would probably liquify too much. Also the Art Clay Copper works best if you put it in a hot kiln so this would crack the glass due to thermal shock. After firing, it has to be dropped into cold water, another reason why it can\'t be used with glass. Question courtesy of Susan Potter...
