The process has much in common with candle making using meltable wax which, using a similar process, can be scented, dyed, and shaped on a small or large scale of production.

Pears soap was made using a process entirely different from other soaps. A mixture of tallow and other fats was saponified by an alkali.This is currently caustic soda (sodium hydroxide) since the ingredients list shows sodium salts of fatty acids, but a chemist reports that in the 1960s, caustic potash (potassium hydroxide) was used.
Nabulsi soap was traditionally made by women for household use, even before the appearance of small soap-making factories in the 10th century. [2] [3] Trade with Bedouins was indispensable for soap-making, both in Nablus and Hebron, since they alone could furnish the alkaline soda (qilw) required by the process. [4]
The moisture content of the soap is also reduced, making the soap hard and long-lasting. And lastly, the color of the outside of the soap turns pale gold, while the inside remains green.
