Is it better to add Liver of Sulphur patina before or after tumble polishing?

The general advice is to add patina at the very end of the process. Dipping your piece in Liver of Sulphur allows you to add beautiful colours to your work. You can then re-polish the 'high' spots on your piece so they have a high shine while the deeper areas remain patina'd. Or simply leave the whole piece with the colours.

Some people have found that putting their patina'd pieces into their tumble polisher contaminates the barrel, shot and liquid. This causes any subsequent pieces tumbled to take on the patina. Other people have had no problem with this.

If you do decide to tumble your piece after adding Liver of Sulphur, it may be wise to thoroughly wash the barrel and shot and replace the liquid with fresh.

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...
