In soap making, there are 2 kinds of infusion.
First: Water infusion.
The water infusion is for the lye-water solution.
Second: Oil infusion.
The oil infusion can be used for the base oils or as an additive.
There are 2 ways to make an ifusion:
1. Heat Infusion
This is the process of boiling the herbs or seeds that are to be infused in the oils or water. You manipulate the heat so that the qualities of the herbs and seeds are extacted.
2. Overtime Infusion
This process requires a length of time. You may not boil your herbs or seeds on the water or oil. In this process, you just let the herbs and seeds extract on its time. Usually around a week.
In my opinion, the best type of infusion jis the overtime infusion, which brings out great results.
In the picture, I am going to infuse tarragon leaves in the oil for my cleansing soap recipe. I am going to infuse through heat because I need the soap asap. :)
