I know soap can be made without lye calculator. I do that myself. disolve my caustic soda in water of any amount then look for the spicific gravity of lye then measure my oils and lye at the ratio of 2:1. But someone told me he uses 4kilograms of caustic soda, dissolve in 4 litters of water and combine the lye solution with 4 liters of oil without cheking the specific gravity of the lye water. I do'nt know the outcome of such a soap. Does anyone has another method of soaping without using lye calculator.
