Hi, I'll make it quick...

100Grams of any material usually ends up as 700ml Basified Liquid...
meaning Content vs Water is 1/7

In my mind this is why its taking 5-10 pulls over multiple days (most guys/gals)

would it not be more efficient to have a 1/1 scenario.. by reducing prior to Base...
Surely that would give the Naphtha an easier time

I realize this would affect the amounts of Lye needed but I'm sure that's no issue for.. you
