NOTE: This project and these instructions have been written for someone who has experience making soap and knows the potential dangers due to working with sodium hydroxide. It will not outline all safety methods of working with dangerous chemicals, it is simply a soap recipe for advanced soapmakers.
- Before beginning, brew 4.38 oz. of green tea and pour into an ice cube tray or a soap mold with small individual cavities and place in freezer. Allow to freeze completely.
- Put on your protective gear. This is very important since you will be working with an extremely caustic base that can and will burn you if you touch it. Noxious fumes are also released from the exothermic reaction that occurs when you mix the sodium hydroxide with water.
- Prepare the lye solution by placing the frozen green tea in the plastic pitcher and weighing the lye in a separate container. Very slowly pour the lye into the tea to prevent scorching, carefully mix in a well-ventilated area and set aside to cool while you prepare your oils.
- Measure the oils and butters in the glass mixing bowl and melt in the microwave. Set aside.
- In one plastic beaker measure out sodium lactate and set aside.
- In second plastic beaker measure out fragrance oil and sea clay and blend together.
- When the tea and lye mixture is around 100° F, stir in the Sodium Lactate.
- When both the lye mixture and the oils are below 100° F you can begin mixing. Add the lye mixture to the oil/butter mixture and stick blend until you reach a light trace.
- Mix in the fragrance/clay mixture and stick blend in short bursts until it is fully mixed.
- Pour the soap batter into the mold and tap the mold on the counter to release any air bubbles.
- Allow to set at least 24 hours or longer until soap is firm enough to unmold and cut. If you have trouble removing soap from the mold, place in the freezer for about 15 minutes and then remove.
- Let soap cure 4-6 weeks. Package and label accordingly.
