• SELF-HARDENING CLAY: Ready to use, this self-hardening clay air dries without firing in 4 or 5 days. Thanks to its natural cellulose fibres, it dries without developing any cracks, even on large surfaces. Once dry, it is very durable and solid. Colour: concrete grey.
• VERY VERSATILE: The clay texture gives this material an excellent plasticity for modelling without firing and is perfect for working very fine details. This multi-functional self-hardening modelling clay can also be moulded (we recommend plaster moulds) and turned in a potter's wheel.
• AN INFINITY VARIETY OF FINISHES: Once dry, this grey self-hardening clay can be painted, varnished, polished, cut or perforated. It can also be waterproofed after complete drying (4 to 5 days) to make non-food airtight containers.
• MINIMUM EQUIPMENT REQUIRED: Once the object is finished, simply allow it to air dry for 4 to 5 days. To speed up the drying process, the object can be exposed to a heat source. It is possible to increase the hardness by finishing the drying process in a domestic oven between 100 and 110ºC.
• LONG-TERM STORAGE: This modelling clay keeps in its original packaging conditions for at least 2 years. As long as it has not dried, this air-hardening clay can be reused and stored indefinitely in a damp cloth inside inside a tightly closed plastic bag.
