Seramiksir SP 1511 Sirius - Artistic High-Fire Glaze (R24647)

SP 1511 Sirius - Artistic High-Fire Glaze

SP 1511 Sirius is an artistic reactive high-fire glaze inspired by the brightest star in the night sky, developing crimson and burgundy flows over a light-colored base. Its glossy, deep surface effect creates strong contrast and gives glazed forms a distinctive character. Supplied in a ready-to-use liquid form, the product can produce varying color intensities and flows on every piece depending on the application thickness, clay body, and firing conditions.

Technical Data and Application

Color Pairing Suggestions

The glossy, contrasting, and dynamic character of Sirius glaze can be paired with the following colors:

Application Notes

• Product preparation: Mix the product thoroughly before application to distribute the pigments and reactive components evenly throughout the liquid. Periodic remixing throughout the application process is recommended.
• Brush application: The product can be applied directly to a clean, dry bisque-fired surface. Apply in even coats and allow the previous coat to dry completely before applying the next one.
• Application thickness: A medium and even application supports the development of crimson and burgundy flows. Reactive effects may remain weak with very thin applications, while excessive glaze movement and flowing may occur with overly thick applications.
• Number of coats: Color intensity and surface depth may change as the number of coats increases. Applying each coat evenly helps achieve more controlled and balanced results.
• Pouring and dipping: For these methods, the consistency can be adjusted by adding approximately 5-10% water. Add water gradually and mix the product thoroughly after each addition.
• Clay body effect: Crimson and burgundy transitions may appear more pronounced on white and light-colored high-fire clay bodies. Dark, iron-rich, or grogged clay bodies may produce a darker, more mineral-like, and intense character.
• Form and texture: The glaze may collect at varying thicknesses across raised, recessed, and textured surfaces. This can emphasize color transitions, shadows, and details of the form.
• Firing effect: The peak temperature and hold time may directly affect the surface gloss and distribution of the crimson and burgundy flows. The same glaze may produce different results with different firing schedules.
• Cooling effect: Controlled, fast, or slow cooling may alter the color tone, surface depth, and appearance of the reactive areas. Each kiln schedule may therefore produce distinctive results.
• Vertical forms: Because the reactive glaze may move during firing, apply it more thinly near the base and keep it away from areas where it may come into contact with the kiln shelf.
• Variations between pieces: Due to its reactive character, natural differences in tone, flow, and texture may occur between pieces even when the same application and firing conditions are used.
• Storage: Store the product in its tightly sealed original packaging at room temperature, away from direct sunlight.
• Safety: Use appropriate protective equipment during application, ensure the work area is adequately ventilated, and store the product out of reach of children.
