- Being in what i hope is my infancy of knowledge on the subject of
reflux column stills, I am looking for personal opinions on whether
or not Polishing with activated charcoal is necessary. I've built
the still just as the instructions read in Bob Lennon's Stillmaker
Page, to the letter, even the used ss scrubbing pads in the reflux
column. My (and others) caluculations predict outstanding results
and purity! Soooooo, does it need polished?
