Thanks to recent improvements, most things are running better in my anodizing setup. But this weird problem keeps occurring.

Two of the same pieces that need deox/desmut connected together here. Both were anodized (badly, see my dozen other recent threads), stripped in lye, rinsed, deox/desmut, then reanodized. One comes out fine, or fine-ish. The other is pitted and when it dries, the pits become white bumps.

Two pieces of the same alloy, under same treatment and anoed in the same run, anodized at different colors, one dark grey, the other less so. Both pitted unacceptably and took dye differently, neither very well.

One was anodized more often than the other, this was one piece’s third run. But both were prepped the same way. I guess matching pieces must always be prepped, processed (and reprocessed) in lockstep, or both thrown out.

Thoughts?
