- Keep filled metals protected during storage. Store wires and sheets separately in plastic bags to minimize scratches.
- Rest it on soft leather to minimize work marks while filing, etc.
- Joins must be aligned perfectly for soldering. There's too little gold to file or even for a black silicone wheel. Just a little filing can expose the base metal core, but you won't know until days later when it tarnishes.
- Try to match the color of the joins by using 14k or 10k yellow gold solder. A yellow tinted sterling solder is also available, but it only comes in one temperature (medium).
- Fill joins without overfilling. Use smaller pieces of solder to avoid big lumps.
- Prevent firescale with cupronil or Firescoff flux.
- Because of the bond between the two metals, the melting point is lower. Never use hard solder. Use medium, easy or extra-easy. A lower temperature flame, like butane, is less likely to burn it. If a small torch is used, use a medium flame and be gentle with the heat.
- Try to fix any scratches or problems with burnishing, which will polish without abrasion. A tumbler with mixed stainless steel shot is a safe way to polish.
- Only use the finest grits for polishing, like blue silicone wheels, and blue - light green radials.
