Decide which herb(s) you will be using and infuse it into 16 ounces of olive oil. See blog post for instructions. Strain and weigh. If it does not weigh 15 ounces, add olive oil to make up the difference. If it's over 15 ounces, remove until you have exactly 15 ounces.

Using the same herb(s), make enough herbal tea that after straining weighs 9 ounces. Cool the tea to room temperature.

Prepare a cold water bath by filling your sink with several inches of cold water and adding ice cubes, or ice packs.

Carefully weigh each item to specified amount. Place the oils in a pot on stove over low heat.

Very slowly and carefully, add lye to herb tea, or distilled water, stirring constantly. It is best to do this in a well-ventilated area.

The temperature of the lye mixture will quickly rise to as high as 200°F. Place the container with the lye mixture into the cold water bath, stirring occasionally until it reaches 100°F.

Stir your oils over low heat monitoring the temperature. The goal is to get both your oils and your lye mixture to 100°F. Use the cold water bath to lower temperatures if needed.

When both the lye mixture and the oils are at 100°F, very slowly drizzle the lye mixture into the oils, stirring constantly.

When trace is reached, pour into molds and cover with cardboard and a blanket to hold in heat. Remove covering after 24 hours.

Remove your soap from your mold once it is firm, and allow to cure for 4 - 6 weeks before using.
