3. Heat 12 oz (354 ml) of distilled water in a heatproof container to about room temperature. Do not use tap water, as impurities can affect the soap quality.
4. Slowly sprinkle the lye into the water while stirring gently with a stainless steel spoon. Never add water to lye, as this creates a dangerous exothermic reaction. The solution will heat up.
5. Allow the lye solution to cool to around 110°F (43°C). Use a thermometer to monitor the temperature.

Step 2: Preparing the Oils

1. Measure the following oils and butters using a digital scale:

• 16 oz (454 g) olive oil
• 8 oz (227 g) coconut oil
• 4 oz (113 g) shea butter
• 2 oz (57 g) castor oil

1. Melt the coconut oil and shea butter in a stainless steel or glass bowl, either using a microwave or double boiler method.
2. Add olive oil and castor oil to the melted mixture. Stir until all oils combine thoroughly. The oils should also cool to 110°F (43°C) before proceeding.

Step 3: Combining Lye and Oils

1. With both the lye solution and oils at similar temperatures (around 110°F), carefully pour the lye solution into the oils. Always pour lye into the oils—not the other way around.
2. Stir gently with a stainless steel or silicone spatula to begin incorporating the mixture.

Step 4: Blending to Trace

1. Use an immersion blender to blend the mixture. Begin blending in short pulses, alternating with manual stirring to prevent overheating the motor.
2. Continue until you reach “trace,” which is when the mixture thickens to a pudding-like consistency. To check trace, lift the blender out of the mixture and drizzle a thin trail on the surface—if it holds its shape for a few seconds, it’s ready.

Step 5: Adding Optional Ingredients

1. If desired, add essential oils for fragrance (e.g., 15-20 drops of lavender or tea tree oil) and stir thoroughly.
2. For natural color, incorporate mica powder or clays into a small portion of the soap base first, then mix back into the main batch.
3. Optional exfoliants like oatmeal or poppy seeds can also be folded in at this stage. Be mindful not to add too much to maintain a balanced texture.

Step 6: Pouring Into the Mold

1. Pour the soap mixture into your prepared mold(s). Use a silicone spatula to scrape every bit from the bowl. Smooth the top with the spatula.
2. Tap the mold on the countertop gently to release any air bubbles trapped in the soap.
3. Decorate the top with optional dried botanicals if using (e.g., lavender buds or rose petals).

Step 7: Curing the Soap

1. Cover the mold with cling wrap or parchment paper. Place a towel or blanket over the mold to insulate the soap and help it gel. Leave undisturbed for 24-48 hours.
2. After 24-48 hours, carefully unmold the soap. If it feels soft, allow another day before removing.
3. Cut the soap into individual bars if needed and place them on a rack or parchment paper, ensuring airflow around each bar.
4. Let the soap cure for at least 4-6 weeks. During this time, the water evaporates, and the soap hardens. Rotate the bars weekly to promote even curing.

Key Timelines	Details
Mixing & Pouring	Approx. 1-2 hours
Unmolding	After 24-48 hours
Curing	4-6 weeks

It’s important to track curing time for the best results. Use the soap after curing when it’s hard, long-lasting, and gentle for the skin.
