Product Features

• This turquoise-blue glaze exhibits yellow-tinted effects and transitions toward green. Blue-green crystals form on the surface.
• High opacity.
• The base remains glossy, while crystals may appear matte.
• In applications of 2–3 coats or more, the glaze may show running tendencies depending on thickness.
• Free of toxic substances.

Note: In crystal glazes, acid resistance depends on the density and distribution of surface crystals. When crystals densely cover the surface, acid resistance is lower. In surfaces with a balanced and controlled crystal distribution, the glass matrix remains continuous, resulting in higher acid resistance. Therefore, chemical durability in crystal-patterned products is directly related to the surface glaze and the user’s production process.

 

Application Methods

Important: To promote crystal formation, both thin and thick applications should be used on the same surface. Excessively thick coverage may result in dense crystals that merge and cover the entire surface, producing a matte, slightly rough “crystal matte” effect. Very thin coverage may result in weak crystal growth.

• For vertical surfaces, apply thicker layers to the upper areas of the form and gradually thin toward the bottom.
• On horizontal surfaces, alternating thin-thick applications help distribute crystals evenly.
• This method ensures each product develops a unique crystal pattern.
• Crystal glazes perform best with spray (pistol) or dipping methods.
• Brush applications: 1–3 coats on the same surface.
• Spray or dipping: add approximately 5–30% water to adjust density.
• Recommended Baumé range: 45–55.

 

Testing Recommendation

• First-time users should prepare test tiles under their own kiln conditions and application methods to evaluate results, both vertical and horizontal.
• In the product image, the glaze was applied on BNC 1200 white porcelain clay. Since the glaze is transparent, its color and artistic effect may vary on colored clays.
• When combining with other artistic glazes, testing is recommended to prevent defects.

 

Care and Cleaning

• Dishwasher use may expose the glaze to high-temperature chemical solutions, potentially causing matting or changes in artistic effects.

 

Safety

• Personal protective equipment is recommended during application.
• Keep glazes away from fire and open flames during use.
• Children should apply under supervision.

 

Storage

• Store in airtight conditions, away from direct sunlight.
• If stored for a long period, the glaze may start to dry. Add water, mix thoroughly, and sieve before use.
• After opening, over time, brushing agents, stabilizers, and antibacterial additives may lose effectiveness. This usually does not affect firing results but may influence application performance (harder application or pre-firing surface cracking). Contact us for recommendations if this occurs.
