Re: Of ships and shoes and sealing wax, of cabbages and kings ......
This is a discussion list dedicated to promoting informed discussion on the
topic of distilling. Sarcasm and abuse has no place on it I can't believe that
you penned that email after we have had discussions both on this list and
privately. I was responding to a question that asked what marbles actualy did
and that is what they actualy do, the relative merits of other material is a
completely different discussion. I will amplify the process, what marbles
actualy do is slow the passage of the vapour in a reflux column alowing the
vapour to cool and the water to condense out and fall back into the pot, and no
amount of sarcasm is going to change that. I am happy to concede that there may
be other materials that do the job better.
