Reversing color changes in titanium anodizing


#1

Having anodized a sheet of titanium to a brilliant green at 125v I
needed to remove the layer. I used Armour Products “Etch Bath.”

To my surprise a series of brief dips reversed the color build up
and allowed me to go back down through the developing colors. I
ended up with a much deeper blue than I was able to achieve with the
rectifier.
