Piezo ceramic turning brown!

[Bencthemusicman]

I've just been tidying up my kit a bit and discovered that nearly all of the piezos have browned, its more obvious near the connections.
I didn't solder these myself so its not that.

Anybody know i this is normal or seen it before?

Thanks

After I peel them, I like to put my piezos in some cold water...this prevents browning.

What a minute...that's what I do with potatoes

I don't know why they brown but I have one I use as a template and the ceramic on it has discolored...I doubt it will affect performance.

The flux splatter can be corrosive, some more than others I think. It may be good practice to clean it up after soldering. I used rubbing alcohol and a q tip. I think there are products out there to neutralize the worst of the flux types.

The piezos on my Rolands are all discolored and they trigger great still.

Thanks guys.

not bothered about the colour as long as they work ok.
