Application Methods

• Suitable for brush application. The recommended application thickness is 2–3 coats.
• For spray gun or dipping applications, it is recommended to add approximately 5–30% water to adjust the consistency.
• Recommended Baumé (°Bé): 40–45.

Testing Recommendation

• We recommend that customers using our glazes for the first time prepare test tiles under their own firing conditions and application methods to evaluate the results. Preparing both vertical and horizontal test pieces according to your application technique will help you better understand the glaze’s behavior.
• The sample shown in the product image was applied over CMR 250 White Casting Body.
• When combining this glaze with another artistic glaze or with other glaze groups, we recommend conducting tests beforehand to avoid possible incompatibilities or defects.

Care and Cleaning

• When washed in a dishwasher, the glaze surface may be exposed to high-temperature chemical detergents. Over time, this may result in slight dulling or changes in the artistic characteristics of the glaze.

Safety

• The use of appropriate personal protective equipment (PPE) during application is recommended.
• Since glazes interact with heat, they should be kept away from fire and open flames during application.
• Children should use the product only under adult supervision.

Storage

• Store the product in a tightly sealed container, protected from direct sunlight and air exposure.
• If the glaze begins to dry after prolonged storage, add a small amount of water, mix thoroughly, and strain before use.
• After opening the container, the application aids, stabilizers, and preservatives contained in the glaze may gradually lose their effectiveness over time. This generally does not affect the fired result, but it may reduce application performance, making the glaze more difficult to apply or causing pre-firing surface cracking.
