Methods

CSDBHP=Closed System Double Boiler Hot Process (one pot inside another, lids on both pots) See below under DBHP.
CSHP= Closed System Hot Process (pressure cooker) A closed system HP method where a pressure cooker is used at the closed system.
CP = Cold Process -Oils, water and lye are added together and no heat is applied in the process. The saponification process produces heat.
CPHP = Crock Pot Hot Process -The fats and lye water are brought to trace, then cooked in a crockpot until the lye is neutralized (finished saponifying the fats). Scent and additives may be added at the end of the cook, then the thick batter is plopped into molds.
CPOP = Cold Process/Oven Process - The soap is made as in CP and then usually placed in a mold and heated in the oven at very low temperatures to achieve a gel.
DBHP = double boiler hot process - A hot process method using a double boiler. Fats and oils are melted in a double boiler, remove and the lye is added as in CP. At trace the soap pot is placed back onto the lower pot full of water with a lid and is cooked on very low simmer for 1 to 2 hours. The soap paste is then placed in molds, cooled and then can be used right away.
DHHP = direct heat hot process - A HP method where the soap mixture is heated by placing the soap pot directly on the stove.
DWCP = Discount Water Cold Process - The water that is added to the lye is slightly discounted to decrease the cure time and then it is soaped CP. (Not for the inexperienced).
HP = Hot Process - All ingredients are added to a pot that is placed over or in a heat source. The heat source can be anything: stove (this is the direct heat reference), microwave, oven, crock pot. The ingredients are often stirred frequently through the various stages of the saponification process. The stirring and heating continue until the excess water is evaporated off. This method allows for the soap to be used once it is cooled.
ITMHP = in the mold hot process - A HP method where the traced soap mixture is placed in a mold and then heated to achieve gel.
M&P/MP = Melt & Pour - Refers to a soap base that is purchased and can be melted and then poured into molds.
MWHP = microwave hot process - A HP method where the soap pot is heated in the microwave.
OHP = Oven Hot Process - An HP method where the oven is used as the heat source.
RDBHP=Regular Double Boiler Hot Process - See above under DBHP.
RT = Room Temperature - Refers to the temperature of oils, fats, and lye
RTCP = Room Temperature Cold Process - As in cold process, the oils water and lye are added together when they are at room temperature.
RTDWCP = Room Temperature discount water cold process - A CP method where the fats, oils and lye are combined at room temperature. The water added to the lye is discounted to decrease cure time.
