SP 1505 – Siena

Recommended Firing Range: 1180–1250°C

Form: Supplied as a liquid glaze in 175 g, 500 g, and 1000 g containers.

Application Characteristics

• In thin applications, the glaze develops tones ranging from reddish-brown to dark amber, creating a surface covered with delicate cream-colored micro variegations. In thicker applications, yellow variegations become more intense and artistic over a reddish-brown background.
• On vertical forms, increasing the application thickness causes the artistic effects to accumulate toward the lower sections of the piece following the direction of flow, while the upper sections become more transparent.
• On horizontal forms, increasing the application thickness results in the surface becoming fully covered with artistic effects, reducing its transparency.
• Features a glossy finish.
• Opaque in appearance.
• Does not exhibit excessive flow when applied within the recommended thickness range.
• Acid-resistant and free from toxic substances.

Application Methods

• For brush application, the recommended coating thickness is 1 to 3 coats.
• For spray gun or dipping applications, it is recommended to add approximately 5–30% water to achieve the desired consistency.
• Recommended Baumé range: 45–55°Bé.

Testing Recommendations

• For customers using our glazes for the first time, we recommend preparing test tiles under their own firing schedules and application methods to evaluate the results.
• Creating both vertical and horizontal test pieces according to your intended application technique will help you better understand the glaze’s behavior.
• The sample shown in the product image was applied over BNC 1200 white porcelain clay. Due to the glaze’s translucent characteristics, its color and artistic effects may vary when applied to colored clay bodies.
• When combining artistic glazes with other artistic glazes or different glaze groups, we strongly recommend conducting tests beforehand to avoid potential compatibility issues.

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 a matte appearance or variations in the glaze’s artistic effects.

Safety Information

• The use of appropriate personal protective equipment (PPE) during application is recommended.
• As glazes react to heat, keep the product away from open flames and ignition sources during use.
• Children should only use the product under adult supervision.

Storage

• Store in a tightly sealed container and protect from direct sunlight.
• If the product is stored for an extended period, some drying may occur. In this case, add a small amount of water, mix thoroughly, and strain before use.
• After opening, the performance-enhancing additives, stabilizers, and preservatives contained in the glaze may gradually lose effectiveness over time. While this generally does not affect the fired result, it may impact application performance, making the glaze more difficult to apply or causing pre-firing surface cracking.
