Hmm,
I read somewhere that over time Br2 attacks glass over long time exposure, maybe it was at higher temperatures. now that I think about it it is most
likely NaBr as that sample was from the small amount I salvaged from the accident.
all above information is intellectual property of Pyro.  |

None of the non-coated portion of my anode was below the surface of the liquid in the cell, so I had no trouble with it. It's plausible that it could
damage exposed Ti, but I'm not inclined to find out.

I can verify bromide attacks 6Al-4V titanium alloy as anode.
