Re: Solution life
When I'm anodizing, my nose picks up the smell that it identifies as "battery acid". Is that really just hydrogen or is the acid slowly leaving the solution? In other words, will the acid stay there for the whole 136 square ft? I keep a log of all my anodizing runs, including the surface area. I'll know definitively when I approach the 136, but will there be any other indications when the solution is nearing the end of its life, for example, more problems with dissolution or decreasing dye depths due to decreasing anodization layer thicknesses?
