Self-Plating Element

Postby Cap'n Canuck » Sat Jan 11, 2014 6:45 pm

So, I pulled the 1500w element out of the keg the other day to replace it with the 5500w one, and discovered that it had self-plated itself in copper. I can't say that I've seen that happen before, but that said, the element hasn't been out of the keg since I put it in, so that's not surprising that I haven't seen it before. :)

Of course, looking at the mesh that I pulled out at the end of a spirit run the other day, it sorta makes sense. It's got to go somewhere, I figure, but I wasn't expecting it to plate the element.. :)

Poor, poor copper. It gave it's all.

Thats pretty neat. It should help with sulfide issues as well.

Self plating? I wonder if the sliver colored nickel or chromium (whatever it is) coating was eroded off the element by the acidic nature of the boiler charge...

As far as I know (and I could be wrong here) most element casings are copper and all that happened was the heat and acid caused the silver colored coating of the element to erode/corrode off and leave you with a shiny copper specimen. Could you try lightly sanding off the copper looking area and seeing if there is the same silver colored coating under it that the original element looked like?

I'm truly curious about this.

What swede says is right. The elements are made from copper and then coated in nickel or incolloy or some other coating. Looks like you have lost your coating, it will still be fine though.

You sir would seem to be correct.

From the manufacturer's webpage: Made of copper tubing with magnesium oxide and nickel plating. UL listed for the USA and Canada. 1 year limited warranty. High watt density.

Yup. Sanding it just made it shinier, and a little scratchy..

Bummer. I was hoping that I had found a free way to suspend stuff in the kettle, and come out with pretty copper stuff. :lol:

Nah, I was just surprised that it went in silver, and came out copper. I never even though to check what the coating was made from.

Yup. Still surprised that it got eaten off though.. I've never tried to measure the PH of a wash.. How acidic is it normally?

Backset is very acidic, i use it to clean copper back to shiny after working it with flame. Just drop the copper pieces in a bucket of hot backset and leave overnight.

Crap, if it'll eat the coating off an element, it must be.. I would never have thought. I wonder how it compares to coke for cleaning tarnished metals. :)

Small Gremilns and Imps suck them while you are asleep. They can't get trace elements from their normal food in this dimension.

I dunno.. I rather prefer imps and gremlins to sulfur compounds reacting with copper to make copper sulfates and precipitating out into the wash. Less boring, and it's not like anything can be done to change either.. :)
