Before starting your work make sure that your work area and all the tools are clean, dry and disinfected with rubbing alcohol.
Using a knife, cut the base of MP into small pieces, to melt quicker. Weigh the base and additives, if you use butters they will need to be melted on a double boiler too. Prepare your fragrance by creating your own mixture from essential oils, extracts or absolutes or use a readymade fragrance. Do not forget to choose your essential oils, extracts, and absolutes carefully, as these aren’t only fragrance makers but can also add quality to your soap. Once the base of MP melts, you will have to work very fast. For the base not to be burned and to keep all the essential qualities, it is important to be kept at no higher than 100°C. Use the kitchen thermometer to watch the temperature. After the base has melted, remove from the double boiler and add in your additives.
Usually all the powders and clays, micas, I mix in my oils and add them to the whole mixture, plus the herbs. Some crafters prefer to add everything straight into the base. It depends on your preferences. Both ways are correct. I also stir with a hand blender using a slow speed, without making foam and to avoid lumps. But these are my personal preferences and habits of work.
Please note that the base will have to be agitated using a spatula from time to time while cooling down. I do this to avoid creating lumps, sedimentation, to cool down faster and so as not to have a film appearing on the top of the mixture.
As the base of the soap will be too hot will have to wait for the temperature to lower down and after stirring gently add essential oils mix or a readymade fragrance. Carefully pour the soap mix into moulds, spray the surface with rubbing alcohol to avoid bubbles.
Allow the soap to settle and fully harden.
