Hi Wayne, Michael, all...
I still feel there is much to recommend time and controlled evaporation and
having batches of Clay rendered into Slurry/Slip/Soup, entering the sequence
and lined up for their eventual turn as they become ready, or are allowed to
Takes no electricity, needs no tech, is happily 'quiet' in it's
process...and will never let you down...even as it also gives one something
to look forward to in a nice way.
