Technical Details and Application

Painting and Glazing

Refsan underglaze ready-to-use paints are highly compatible with the Rubi bisque. Achieving a non-porous, lead-free finish through correct glazing is essential for hygienic, daily beverage contact.

• Ceramic Application: Fire between 1040°C and 1050°C for a professional, high-gloss finish.
• Tile (Çini) Application: Traditional tile glazes maturing at 900°C – 920°C can also be used for artisanal, decorative styles.

Decorative Use with Acrylic Paint

• Suitable only for display-oriented decorative projects (no kiln firing required).
• Safety Warning: Acrylic-finished cups are not food-safe. Do not use for drinking if finished with acrylics.
• A protective varnish is recommended post-painting to preserve the decorative finish.

Craftsmanship & Variations

Fired at 1050°C to reach its sturdy bisque state, each Rubi cup carries the unique marks of artisanal production. Natural variations in thickness, size, or clay tone are hallmarks of handcrafted ceramics, ensuring every set has its own character.

Firing Safety & Guidelines

• Surfaces must be thoroughly cleaned of dust and completely dry before glaze application.
• Strictly follow the temperature requirements of your specific glaze type.
• Perform a test fire to observe how kiln atmosphere influences the final bisque color.
