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 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....
