It is most likely cuprous oxide Cu2O. As opposed to the black colored copper(II)oxide , the cuprous or copper(I)oxide is a fine red/orange colored powder that looks very much like the substance in copper antiseize spray. It can form on the copper parts in the still through reaction of the metal with oxygen from air or from preexisting copper(II)oxide under certain conditions....usually when a reductive agent is present (e.g. aldehyde content or sulfur dioxide from campden residue).

I get something that looks like this in my column after a puke from an AG stripping run. I always break down and give everything a hot water rinse after a stripping run and that film runs out.

That looks like the fats or oils mixed with unfermentable starches that line the inside of my boiler after stripping runs On Barley runs, it's dark like that, on high corn runs, its more of a pasty yellow color.

I buttered the bottom of the pot like always. This is actual off colored flotsam on top.

Smelled great like rich fruit reduction but I didnt taste it.

The blue Crystal that were left behind in my glass proofing parrot disturbs me.
