I have been using sodium bisulfate solution for anodizing with great results for a while now. The other day I repainted the light post in front of my house. The ornament on top was black like everything else and I wanted to see if I could anodize it like I did the decrotive balls on the ends of the ladder rail in posting http://www.hobby-machinist.com/showthread.php/14708-Another-anodizing-project . I stripped the paint off the piece and it definitely appeared to be aluminum. I cleaned it up good and polished it for anodizing. I went through all the processes that I normally do for anodizing. The whole time handling this it appeared to be aluminum What aluminum alloy is hard to say. When I put it in the anodizing tank it reacted just like the other aluminum I have anodized. It appeared to get a layer to it similar to the other parts I have done. Then I tried to dye it. It would not take the dye. I figured it was not a good alloy to anodize so I sprayed it gold and put it on the lamp post light.
The tank solution was performing perfectly good the day before I tried this anodizing of the ornament. Now the solution will not successfully anodize my parts I have been anodizing. What happened to the solution? Did the metal the light ornament was made of contaminate the solution? I will have to refill the tank and start over to get my process back where it was.
