You should go one step further and simmer (NOT BOIL) the lye until it is a dry powder. Then you can dissolve the correct amount. You can also check the pH for 'neutrality' or 'baseness' using litmus paper. You want your soap to have neutral pH. Hugely important, and hugely hugely important for soap used on children, the elderly, or beautiful ladies with radiant skin. Not so important for macho manly men that don't care about walking around with huge chemical burns on their dumb selves.
