Ok I've done my polishing using the barrel, I loved the outcome but I have this problem is like the firescale on the hole with jumpring attached.Hope I make sense.
Is there any way I can removed it? Picture attached.
Unfortunately, the photo is a bit grainy when blown up, so I am unable to see what you're talking about. What I'm seeing in the photo looks more like a mark from where the hole was punched which simply needs to be polished away.
There are a lot of good sources out there on the subject of firescale if you wish to learn more about this. In a nutshell, firescale is damage done to the Sterling silver by overheating it, allowing excess oxygen in the metal causing damage to the Sterling. It appears as grayish, duller patch-like areas on the silver after it's been buffed. Sometimes the firescale is only "skin deep" so-to-say" and can be polished or sanded away. Other times, the damage goes a bit deeper. Depletion guilding the Sterling silver by repeatedly heating and pickling will raise a layer of fine silver on the surface (while destroying the copper) which may help cover it up.
There are also numerous products available to help prevent firescale such as surface preparations and the use of a hard charcoal block as your soldering pad. I hope you are able to fix the problem!
