Seramiksir Petrol Green Engobe AST 314 - 175 g (R24709)

Seramiksir Petrol Green Engobe AST 314 - 175 g

Seramiksir Petrol Green AST 314 is an engobe developed to give white, red, and naturally colored clay bodies a uniform base in deep petrol green tones. It can be applied to leather-hard or completely dry, unfired clay surfaces and produces a natural, matte, and opaque appearance after firing. It can be used to cover the color of the clay body, smooth the surface, and prepare a distinctive base for subsequent decoration or glazing.

Technical Data and Application

Color Pairing Suggestions

Petrol Green AST 314 can create a deep, matte petrol green surface on its own or be combined with different decorative colors and glazes:

Application Notes

• Surface Preparation: Apply the engobe to a clean, dust-free, unfired clay surface. Leather-hard surfaces may provide more consistent adhesion.
• Preparation: Mix the product thoroughly before application until all settled material is fully dispersed.
• Brush Application: It can be used for localized decorations or full-surface coverage. Apply each coat in a different direction to achieve even coverage.
• Dipping Application: This method can be preferred to achieve more uniform, smooth surfaces without brush marks.
• Sgraffito Application: Once the engobe reaches leather hardness, the surface can be carved to reveal the color of the clay underneath.
• Drying: Once application is complete, allow the piece to dry completely before bisque firing.
• Bisque Firing: Once drying is complete, fire the piece using a schedule suitable for the selected clay body.
• Glazing: The natural matte appearance can be preserved, or a transparent or colored glaze can be applied after bisque firing.
• Color Character: The clay color, application thickness, and firing temperature may affect the petrol green tone and opacity of the engobe.
• Clay Compatibility: Incompatible shrinkage rates between the engobe and clay body may cause cracking, blistering, or separation from the surface.
