A videographer friend who knows I weld/sculpt in steel, asked me a question about anodized aluminum, and I could not find a thread here that could answer it. He has some small parts/knobs that are currently red anodized aluminum, and wants them anodized black, so they will blend in with the rest of his gear.

OIL PAINTING ON CANVAS, 3 X 3 FEET, 2008.

FROM MY SOLO EXHIBITION "ADORN" - JEWELLERY AND PAINTINGS INFLUENCED BY MY JEWELLERY DESIGNS.

This is a painting I did back in 1986 called Meditation Mandala. It was the original idea for the KING GATES.

I have several old silver dollars passed down from my grandparents. None of them are rare dates, or particularly valuable, but they are all precious to me. They are all worn a bit, and some have a lovely natural looking worn silver color. I would call it 'battleship grey' or 'dove grey'. Very natural looking for 120 year old coins. The coins are all 90% silver and 10% copper. They are known as Morgan Dollars. My problem is that several of the coins were polished or cleaned somewhere along the line, so that they now appear unnaturally white or bright silver. I would like to return the bright coins to their original color before they were cleaned...but I do not know how to go about this. I'm sure if I left them alone for 50-60 years, they would re-tone on their own...but I'm eager to give nature an assist. I was hoping someone with skills in metal coloring could guide or direct me to recipe's or procedures that might be useful in trying to return these sentimental items to their original natural color. I have several smaller coins (dimes and quarters from the 50's & 60's) that I can use as practice pieces if some experimentation and or skill development is required. Thank you, so much, in advance for any guidance you can give on this matter.
