SIO-2 PF Red Low Fire Pottery Clay, 27.6 lb (Cone 06-04) Natural Modeling Clay for Wheel Throwing & Hand Building

SIO-2 PF Red Low Fire Pottery Clay, 27.6 lb (Cone 06-04) Natural Modeling Clay for Wheel Throwing & Hand Building

LOW FIRE: With a firing range of Cone 06-04 (970ºC to 1055ºC), this earthenware clay is the perfect choice for both amateur and professional artists. Great for potters with electric home kilns! HIGHLY VERSATILE: This traditional red ceramic clay is valued for its smoothness, plasticity, consistency and vibrant color once fired. 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. IDEAL FOR GLAZES: PF Red Earthenware clay perfectly compliments most typical ceramic glazes. Can be glazed in both single and twice firing processes. MANUFACTURED SINCE 1874: Made in Spain by Ceramica Collet S.A., with ACMI non-toxic AP-Certification. Traditional red earthenware clay. It is a high quality and polyvalent clay, very popular for its fineness and plasticity. Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and twice firing processes. Incredible results in reducing atmosphere can be obtained (metallic reflection technique). Available in extruded body (moist form), being suitable for wheel-throwing, shaping and modeling. Firing range: 970-1055ºC / Cone 06-04 Water content (throwing): 22% Plasticity (IP Atterberg): 17 Carbonate content (CaCO3): 10% Drying shrinkage: 5.5% Firing shrinkage 1000ºC: 0.6% Porosity (water absorption) 1000ºC: 13.5% Dry bending strength: 6.6 N/mm2 Fired bending strength 1000ºC: 27.9 N/mm2 Thermal coefficient 1000ºC (25-500ºC): 77.7x10^-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.
