So I just finished the 2nd brew with a pair of heatsticks I built. They are 1500w elements from lowes and I was brewing a light rye ale.
After removing the elements I noticed they had black all over them. Like they were burnt. It doesn't smell and doesn't appear to have come off in the beer in any way. When I cleaned them it started to flake off. After leaving them hanging up for an hour all the black started cracking and peeling and flaking off.
Any idea what it is or what is causing it and if I should be worried about it?
I know mine tend to get a white film on them either from proteins or minerals (guessing). Black stuff?? Hmm, maybe you had some of the same proteins minerals burn onto them. Just a guess. I'm sure you will have someone come by soon with a better answer and idea of what it is.
Just completed another brew and no black stuff this time. Maybe it had something to do with the rye? Not sure.
One thing I noticed when I cleaned them pre brew was that it seems to be a layer of chrome or metal or something that is flaking off the element. One of them is now completely cleaned back to bare metal the other is about 80% there. Not sure what the coating is that these elements have and if its an issue?
