Seramiksir White Engobe AST 121 - 175 g

Seramiksir White Engobe AST 121 is an engobe that covers the surface of red, dark, and naturally colored clay bodies to create a uniform white base. It is applied to leather-hard, unfired clay and produces a natural matte surface after firing. It can be used to alter the color of the clay body, prepare a decorative base, and enhance the appearance of paints or glazes applied over it.

Technical Data and Application

Color Pairing Suggestions

White AST 121 can create a matte white surface on its own or be colored with suitable pigments and oxides for decorative applications:

Application Notes

• Surface Preparation: Apply the engobe to a clean, dust-free, leather-hard clay surface.
• Brush Application: It can be used for localized patterns, decorative lines, and full-surface coverage. Apply each coat in a different direction to achieve an even surface.
• Dipping Application: This method can be preferred to achieve more uniform, smooth surfaces without brush marks.
• Drying: Allow the engobe-coated 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.
• Coloring: Different shades can be prepared using suitable pigments and oxides. Mixing ratios should be tested in advance.
• Clay Compatibility: Incompatible shrinkage rates between the engobe and clay body may cause cracking, blistering, or separation from the surface.
