I don't exactly know what I have here. It is very badly damaged and covered with a gritty sandy substance.
No pics yet but it is so bad at the moment you have to look at it at an angle to see anything and under a loupe you can't see anything at all!
If I scrape away the "sand" it seems to be coming up silver coloured. I don't think it is solid silver. What is the best way to clean this?
I have it in distilled water at the moment. Is this the best place for it (probably for quite a long time)?
