Thanks for the feedback Amerdunbar & CarWiz.....

Amerdunbar....your comments on hot glue in the bath are helpful though not perhaps definitive since I presume you're not yet sure (?) whether long-term continuous exposure of such glues in a nickel bath may contaminate the bath or not. If I'm mistaken about this, and you know that there are no problems longterm with continuous exposure, then please update this thread.

CarWiz.....I don't understand how the heater could plate out if it is not electrically connected to one of the electrodes? Perhaps it just oxidized in the acidic nickel bath?

So, I'm surprised 88 people have viewed this thread already and yet very little feedback on what can or cannot be left in a nickel bath indefinitely without contaminating and/or corroding terribly.

Perhaps I need to be more specific in the question of this thread....Let me rephrase.....what materials (metallic, polymer, glass or otherwise) if not connected electrically to the electrodes in a nickel bath can survive indefinitely within the bath and not cause any problems whatsoever. My bit of research thus far suggests that the following may be okey but any further wisdom from people would be good.

1) Titanium?
2) Glass, specifically Pyrex, but perhaps other types as well?
3) Stainless Steel, if in the 300 series, but perhaps others?
4) PP, PEX, PVC, and perhaps others?

I should think it would be a helpful (though minor) addition to this forum to know what materials definitively can be placed and used within a nickel bath long-term without deleterious effects to the chemistry of the bath. So, if the list of four materials above could be subtracted from, or added to, or further clarified and confirmed, this woudl be good.
