SP 1400 Crackle - Artistic High-Fire Glaze

Technical Data and Application

Color Pairing Suggestions

The transparent, crackled surface of Crackle glaze can be paired with the following tones:

Application Notes

• Crackle formation: The crackle pattern may begin to form during the kiln’s cooling stage and can continue developing for several days after the piece has been removed from the kiln.
• Brush application: Applying even, uniform coats is recommended for a balanced surface. Allow the surface to dry completely between coats and apply each coat in a different direction.
• Application thickness: Glaze thickness may affect the size and density of the cracks. Thicker applications may produce wider cracks, while thinner applications may create a finer, denser crackle pattern.
• Enhancing the texture: On decorative pieces, the crackle network can be emphasized after firing by applying suitable decorating ink or diluted oxide and then wiping it from the surface.
• Clay body selection: The crackle pattern appears clearer on white high-fire clay bodies. Its transparent structure allows the underlying clay color and underglaze decorations to remain visible.
• Dipping and pouring: Depending on the required application consistency, 5-10% water may be added. Add water gradually and in a controlled manner.
• Mixing: Mix the product thoroughly before application to achieve a uniform consistency.
