Among the many ways to create soap, hot process soap techniques stand out for their grounded, hands-on approach that honors tradition and natural ingredients. This method embraces the slow rhythm of time and the earth’s gifts, crafting bars that are honest, healing, and deeply rooted in ancestral knowledge.

Whether you are drawn to the rustic charm of handmade soap or seeking a mindful way to care for your skin, this guide will walk you through the essentials of hot process soapmaking. You will discover how to blend simple, natural ingredients with time-tested methods to create small batches of soap that carry the spirit of the Taíno heritage and the warmth of handmade integrity.

Understanding Hot Process Soap Techniques: A Grounded Approach

Hot process soap techniques involve cooking the soap mixture to speed up saponification - the chemical reaction that turns oils and lye into soap. Unlike cold process soap, which cures over weeks, hot process soap is cooked and ready to use sooner, though it still benefits from some curing time for optimal quality.

This method is deeply connected to the earth and its cycles. It uses natural, honest ingredients like olive oil, clay, and pure water, avoiding shortcuts or synthetic additives. The process is hands-on and soulful, inviting you to slow down and appreciate the transformation happening in your pot.

Key Benefits of Hot Process Soap Techniques

• Faster turnaround: Soap is usable in days rather than weeks.

• Rustic texture: The soap has a natural, handcrafted look and feel.

• Customizable: You can add clays, herbs, and natural colorants.

• Durability: Hot process soap tends to be harder and longer-lasting.

  
  

This technique honors the ancestral wisdom passed down through generations, especially within the Taíno community, where natural remedies and handmade crafts are treasured. It is a way to connect with heritage while creating something practical and beautiful.

Essential Ingredients and Tools for Hot Process Soap Techniques

To begin your journey with hot process soap techniques, gather these simple, natural ingredients and tools. Each element plays a vital role in crafting soap that is both effective and respectful of the earth’s gifts.

Ingredients

• Olive oil: A staple in traditional soapmaking, known for its moisturizing properties.

• Coconut oil: Adds hardness and cleansing power.

• Lye (sodium hydroxide): The essential alkali that reacts with oils to form soap.

• Water: Purified or distilled water to dissolve the lye.

• Natural clays: Such as bentonite or kaolin, for color.

• Essential oils or natural fragrances: Optional, for gentle scenting.

  
  

Tools

• Stainless steel or enamel pot: For cooking the soap mixture.

• Heat-resistant mixing bowls: For combining lye and water safely.

• Stick blender: To mix oils and lye thoroughly.

• Thermometer: To monitor temperatures.

• Soap molds: Silicone or wooden molds lined with parchment paper.

• Protective gear: Gloves and goggles for safety when handling lye.

  
  

Safety First

Handling lye requires respect and caution. Always add lye to water (never the reverse), work in a well-ventilated area, and wear protective gear. This mindful approach reflects the respectful and soulful nature of the craft.

How Long Does Hot Process Soap Need to Cook?

The cooking phase is the heart of hot process soap techniques. It is where oils and lye fully combine, transforming into soap through heat and time.

Typical Cooking Time

• The soap mixture usually cooks for 1 to 2 hours on low to medium heat.

• Stirring regularly helps the mixture reach the "gel phase," where it thickens and becomes translucent.

• The soap is ready when it reaches a thick, mashed-potato consistency and passes the "zap test" (no tingling sensation when touched to the tongue).

  
  

Why Cooking Time Matters

Cooking ensures the soap is fully saponified, making it safe and gentle for skin. It also allows you to add natural clays or herbs without damaging their properties, as the heat is controlled and gradual.

Post-Cooking Steps

• After cooking, the soap is scooped into molds.

• It cools and hardens within 24 to 48 hours.

• Though usable immediately, curing for 1 to 2 weeks improves hardness and longevity.

  
  

This patient process honors the small batch, handmade integrity that defines artisanal soapmaking.

Crafting Your Own Hot Process Soap: Step-by-Step Guide

Creating soap with hot process soap techniques is a rewarding ritual. Here is a simple, practical guide to get you started:

🌿 Ancestral Soap Recipe: A Mild Hot Process Blend

This recipe blends gentle oils and earth-based elements to create a skin-loving, rustic bar of soap using the hot process method. Designed for a mild pH and deeply moisturizing properties, it's ideal for those seeking tradition-rooted, handmade care.

Ingredients (for ~2.5 lbs of soap):

• 400g Olive Oil (pomace)

• 250g Coconut Oil (76°F)

• 100g Shea Butter

• 50g Castor Oil

• 285g Distilled Water

• 102g Sodium Hydroxide (Lye)

• 1 tsp Rose Clay

• 15g Essential Oil (Lavender or Lemongrass)

• Optional: dried herbs (chamomile, calendula)

  
  

  🧼 This recipe is superfatted at 5% and results in a mild, creamy bar with a final pH around 8.5–9

Step 1: Prepare Your Workspace and Materials

• Set up in a well-ventilated area.

• Wear gloves and goggles.

• Measure oils, lye, and water precisely.

  
  

Step 2: Mix Lye and Water

• Slowly add lye to water, stirring gently. (Do not add the water to the lye.)

• You may cover as desired.

• Let the solution cool to about 120°F (49°C).

  
  

Step 3: Heat Oils

• Warm your oils in the pot to around 120°F (49°C).

• Combine all oils thoroughly.

  
  

Step 4: Combine Lye Solution and Oils

• Slowly pour the lye solution into the oils. Do not add lye water if difference in temperature between oils and lye water is higher that 10°F around 110°F–120°F (43°C–49°C).

• Use a stick blender to mix until "trace" - the mixture thickens and leaves a trail when drizzled.

  
  

Step 5: Cook the Soap

• Place the pot on low heat.

• Stir frequently to prevent burning.

• Cover the crockpot and let the soap cook for 45–60 minutes, stirring occasionally. You'll see the soap transform through phases — applesauce, mashed potatoes, then glossy Vaseline-like texture.

  
  

Step 6: Add Natural Additives

• Stir in clays, herbs, or essential oils. See our clays blog too.

• Mix well but gently.

  
  

Step 7: Mold and Cool

• Pour the soap into molds.

• Cover and insulate to retain heat.

• Let cool and harden for 1-2 days.

  
  

Step 8: Unmold and Cure

• Remove soap from molds.

• Allow to cure in a dry, ventilated space for 1-2 weeks.

  
  

This process is a beautiful blend of time, patience, and ancestral knowledge, creating bars that nourish your soul.
