- Distilled water
- Oils and fats (such as olive oil, coconut oil, and shea butter)
- Thermometer
- Soap mold
- Fragrance oils (optional)
- Colorants (optional)
Preparing the Wood Ash
Before using wood ash in soap making, it’s essential to prepare it properly. Here’s how:
Collecting and Storing Wood Ash
Collect wood ash from your wood stove or fireplace, and store it in a dry, well-ventilated area. Make sure the ash is completely cool before handling it.
Leaching the Wood Ash
To remove impurities and excess potassium, you need to leach the wood ash. To do this:
- Mix 1 part wood ash with 2 parts distilled water in a bucket.
- Stir the mixture well and let it sit for 24-48 hours.
- Strain the mixture through a cheesecloth or a coffee filter into another bucket. Discard the solids.
- Repeat the leaching process 2-3 times to ensure the ash is clean and free of impurities.
Calculating the Lye Concentration
To make soap, you need to calculate the lye concentration of the wood ash. Here’s how:
Testing the pH Level
Use pH test strips or a pH meter to test the pH level of the leached wood ash solution. The ideal pH level for soap making is between 12 and 14.
Calculating the Lye Concentration
Use the following formula to calculate the lye concentration:
Lye concentration (in %) = (pH level – 7) x 0.1
For example, if the pH level is 13, the lye concentration would be:
Lye concentration (in %) = (13 – 7) x 0.1 = 0.6%
Mixing the Lye Solution
Once you have calculated the lye concentration, you can mix the lye solution. Here’s how:
- Mix the leached wood ash solution with distilled water to achieve the desired lye concentration.
- Stir the mixture well and heat it to around 100°F (38°C) to dissolve the lye.
Mixing the Oils and Fats
While the lye solution is cooling, you can mix the oils and fats. Here’s how:
- Combine the oils and fats in a separate container and heat them to around 100°F (38°C) to melt the solids.
- Stir the mixture well and add fragrance oils and colorants (if using).
Blending the Lye Solution and Oils
Once the lye solution and oils have cooled to around 100°F (38°C), you can blend them together. Here’s how:
- Slowly add the lye solution to the oils and fats, stirring constantly.
- Use an immersion blender to mix the ingredients until they reach a consistent texture.
Pouring the Soap into a Mold
Once the soap mixture has reached a consistent texture, you can pour it into a mold. Here’s how:
- Pour the soap mixture into a soap mold, making sure to fill it to the top.
- Tap the mold gently to remove any air bubbles.
- Use a spatula or spoon to create a texture or design on the surface of the soap (if desired).
Curing the Soap
After pouring the soap into a mold, you need to let it cure. Here’s how:
- Let the soap sit in the mold for 24-48 hours to allow it to harden.
- Remove the soap from the mold and cut it into bars.
- Place the soap bars on a wire rack or tray, making sure they don’t touch each other.
- Let the soap cure for 4-6 weeks, turning the bars occasionally to ensure even drying.
Tips and Variations
Here are some tips and variations to keep in mind when making soap with wood ash:
- Use a variety of oils and fats to create unique and personalized soap recipes.
- Add fragrance oils and colorants to create different scents and colors.
- Experiment with different mold shapes and sizes to create unique soap shapes.
- Consider adding exfoliating ingredients like oatmeal or coffee grounds to create a scrubbing soap.
