VERY MALLEABLE FIRE CLAY - This 100% natural potter's clay is distinguished by its great malleability. In case your modeling clay dries, it can be recovered with water. Fired in a pottery kiln between 950 and 1050°C.
CLAY FOR SCULPTURE, MODELING, POTTERY - While this clay is ideal for turning on a potter's wheel, Pébéo modeling clay is easy to model, with or without spatulas and other modeling tools. It can also be molded (we recommend plaster molds).
A FIREABLE CLAY WITH AN EXCEPTIONAL FINISH - Once dry, this white modeling, sculpture and pottery clay can be polished, cut or perforated before being fired. Its behavior with ceramic glazes is exceptional. The raw color persists after firing.
DRYING AND FIREING - Once your piece is finished, this white sculpture, pottery and modeling clay must be dried for 2 to 5 days at room temperature. It must then be fired in a ceramic kiln (950-1050°C). Drying and firing conditions vary depending on the size and shape of your object.
LONG STORAGE - This pottery, modeling and sculpture clay is unalterable in its packaging for at least 2 years. Once opened, it can be stored indefinitely in a damp cloth inside a closed plastic bag. If the clay block dries out, it can be recycled by kneading it with water.
