The recipe for making PCM-15, a phase change material with a melting point of approximately 18°C (65°F), is as follows:

1. Ingredients:
   • 5 cups (1.2 L) of water
   • 1 cup (240 mL) of sodium sulfate
   • 1/4 cup (60 mL) of table salt (sodium chloride)
   • 4 teaspoons (20 mL) of xanthan gum (optional, for thickening)
2. Instructions:
   • Add 5 cups of water to a pot and heat it on the stove
     
   • Add 1 cup of sodium sulfate and 1/4 cup of table salt to the water
     
   • Stir the mixture until it begins to slightly boil
     
   • Continue stirring until the salts are mostly dissolved. It's okay if some remain undissolved
     
   • If desired, add 4 teaspoons of xanthan gum and simmer for a few more minutes to thicken the mixture.
   • For a more gel-like consistency, continue boiling for about 30 minutes
     

This PCM mixture will have a melting point of about 18°C (65°F) and can provide significant cooling effects. The recipe does not require precise measurements, making it easy to prepare with basic kitchen tools
