Ingredients:

  • 250 grams Ball Clay
  • 100 grams Black Iron Oxide (Fe₂O₃)
  • 100 grams Gerstley Borate
  • 50 grams Flint or Silica
  • 2-5 grams Water (adjust as necessary)

Instructions:

  1. Clear your workspace and ensure proper ventilation. Wear a dust mask and gloves for safety.
  2. Using a digital scale, weigh out 250 grams of Ball Clay and add it to your mixing container.
  3. Weigh 100 grams each of Black Iron Oxide and Gerstley Borate, and add to the container.
  4. Finally, add 50 grams of Flint or Silica.
  5. Mix the dry ingredients thoroughly using a spatula or a whisk until well combined.
  6. Measure and add 2 grams of water. Mix until you have a homogeneous paste; adjust the water gradually for a thick, creamy consistency.
  7. Apply a small amount to a test tile and fire it at Cone 10 temperature (typically around 2381°F or 1305°C) to see the final color.
  8. Once satisfied with the result, store the stain in an airtight container to prevent drying out.
