A quantity of caustic soda is precisely calculated against the saponification values of the
fats being used and measured by weight.  It  is then carefully mixed with the correct amount of 
triple-purified springwater.  As a result the water heats to nearly boiling. After the solution
 is cooled, it is added to the blend of oils and fats.
"Grandma's soap" had it's rough reputation because there was no accurate way to calculate
or measure the correct amount.  Because the caustic solution is totally taken up in the saponification
(soapmaking) process, our soaps are gentle and mild.
