'Thanks' to our own Chuck H, I recently found some ferric chloride solution in quantity - and am about to embark on coloring composite steel. More correctly, learning to color.....
My question to those of you here successfully doing this is 'how long' does your 15% FeCl seem to last from job to job before having to replace it? I have a 3" I.D. capped, pvc pipe that holds right at one gallon of solution. I plan on only a 5-10 sec. maximum immersion with bores/etc. plugged, but still the stuff can't last forever. Any experiences shared are appreciated.
