Here are two newer micromosaic pieces that I brought back from Italy. They have more modern rotating pin clasps on the back. They are stamped Italy and are set in brass. The blue is actually almost a black navy - much darker than in the photos. They have twisted brass decoration around the outside. Which is where the problem is.....there is green corrosion happening there!!! :0 None of my other pieces, stored in the same jewelry box, have any corrosion - whether they are old or new. But these two have quite a bit of it and it was not there when I brought them back. They have not been examined for some time.......I have pieces with them that are also brass and have been in the box for 30 or more years with no corrosion on them. I tried a soft toothbrush, hoping it might come off if it was loose - no dice! Now I need to clean these things up, and hopefully prevent any more from happening. You can see it around the edge in the pics. I have looked on the net and found lots of ideas on how to clean the tiles, but nothing about corrosion on the brass setting. Can anyone give me advice on this please?
