Applications & Recommendations
Artistic Production
Suitable for artistic ceramic work requiring fine surfaces, precise details, and elegant forms.
Decorative Products
Can be used for forming vases, decorative objects, figurines, and thin-walled decorative pieces.
Hand Building
Suitable for slab building, coil building, and hand modeling. Its fine composition makes surface finishing and detailed modeling easier.
Wheel Throwing
Its vacuum-packed and plastic composition makes it suitable for wheel-throwing applications.
Underglaze Decoration
Suitable for decoration with underglaze colors. The selected color, glaze, and firing schedule must be compatible with the porcelain body’s firing range.
FIRING & GLAZE COMPATIBILITY NOTICE
This product can be used in a single-firing process. Bisque firing at a high temperature may reduce the body’s water absorption and prevent the glaze from adhering sufficiently to the surface. The glaze maturation temperature, clay body firing range, and selected firing method should be evaluated together.
DEFORMATION NOTICE
Thin or wide forms may bend, slump, or deform when fired for a second time at high temperatures. Ceramic pieces should be positioned evenly in the kiln, suitable supports should be used, and a controlled firing schedule should be applied.
Product Advantages
Fine & Smooth Composition
Its fine-grained body helps produce clean surfaces and clearly defined details.
Suitable for High-Temperature Firing
Suitable for porcelain and high-fire ceramic applications within a glaze firing range of 1180–1220°C.
Aesthetic Fired Color
When used with a transparent glaze, it creates a simple and elegant cream-toned surface.
Suitable for Decoration
Can be used with underglaze decoration, ceramic colors, and compatible high-temperature glazes.
High Dry Strength
Its dry strength of 40 kg/cm² supports the structural integrity of ceramic pieces during drying and handling.
