How to Use

1. Prepare your clay body: Use a bisque-fired clay body with a prior firing temperature exceeding 800°C. White porcelain or high-white clay is recommended for the best color vibrancy.
2. Sand if needed: If the surface is too smooth, lightly sand the bisque to improve crayon adhesion and color uptake.
3. Clean & moisten the surface: Brush away any dust and lightly dampen the clay surface before applying the underglaze crayon.
4. Draw your design: Apply the crayon directly to the bisque surface with even, confident strokes. Build up color by layering as desired.
5. Apply glaze promptly: Once your design is complete, apply a clear glaze using a spraying or dipping method. Avoid brushing the glaze over your design to preserve pattern integrity.
6. Fire as normal: Load into your kiln and fire within the recommended temperature range for stunning, permanent results.
