And the first thing he said, it was, did you passivate it? You know, that that characteristic that you're describing has a very odd dull, kind of dulling experience. It's really difficult to explain. Charles: Apparently, my use of just star sand,. sprayed it over my, my brand new stainless fermentation vessel, let it sit until it dried.
