Just as the name suggests, the cold process method of soap making does not require heat to create soap. With this method the lye, an essential ingredient in soap making, is blended with the oils/fats called for in the recipe in order to initiate saponification – the name for the reaction that forms soap from the combination of oils/fats and lye. After saponification, the soap is allowed to cure for several weeks to reduce its moisture content.
