SIO-2 Cellulain High Fire Paper Porcelain Clay, 11 lb (Cone 6-8) Natural Modeling Pottery Clay for Wheel Throwing & Hand Building

HIGH FIRE: With a firing range of Cone 6-8 (1230ºC to 1270ºC), this paper porcelain clay is the perfect choice for potters seeking a stable formula to create impossible-looking porcelain pieces.

HIGHLY VERSATILE: This amazing paper ceramic clay is valued for its presence of paper fibers, which helps avoid cracks and deformations when firing. Can be thrown on a wheel or used for hand-building & modelling.

PREMIUM QUALITY: All SIO-2 clays have are non-toxic and have been rigorously tested through strict quality standards, making them the ideal choice for both professional and amateurs alike.

AMAZING UNGLAZED: Cellulain clay has a distinguishing final texture that is best when left unglazed.

MANUFACTURED SINCE 1874: Made in Spain by Ceramica Collet S.A., with ACMI non-toxic AP-Certification.

Cellulain is a translucent white porcelain paper clay which stands out for its high plasticity, what makes it exceptional for modelling. It is especially designed for creating impossible shapes with porcelain. The presence of paper fibres inside avoid formation of cracks and deformations problems. Its formula is very stable and provides a secure firing range between 1230 and 1270°C. Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body. Presented in a practical 5 kg cylindrical format with double packaging. Firing range: 1230-1270ºC / Cone 6-8 Biscuit temperature: 1000ºC / Cone 06 Water content: 27% Plasticity (IP Atterberg): 11 Carbonate content (CaCO3): 0% Drying shrinkage: 5.1% Firing shrinkage 1250ºC: 11.4% Porosity (water absorption) at 1250ºC: 2.8% Dry bending strength: 4.5 N/mm2 Fired bending strength 1250ºC: 21.0 N/mm2 Thermal coefficient 1250ºC (25-500ºC): 64.1x10-7ºC-1 Storage: Protect ceramic clay bodies from direct sunlight, avoiding excessive temperature changes and protect from frost. Use: Technical details are available with information on the characteristics of each product and its use. It is recommended to test clay body prior to large scale use in order to verify suitability in both the ceramic process (shaping, drying, firing and decoration) and the final application that is expected to be obtained. Safety: All SIO-2 clay bodies are certified by the Art & Creative Materials Institute (ACMI) and conform to ASTM D-4236 safety guidelines.
