Soap making supplies include essential materials needed to create homemade soap. The primary ingredients are lye, which is a caustic substance that helps in the saponification process, and fats or oils, such as coconut oil or olive oil, which provide the base for the soap. Other supplies may include fragrance oils for scent, colorants for visual appeal, and molds to shape the soap. In addition to these core ingredients, soap makers often use safety gear like gloves and goggles to protect themselves from lye. Other helpful tools include thermometers to monitor temperatures and mixing utensils for combining ingredients. These supplies ensure a safe and enjoyable soap-making experience.
