Hobby Ceramics Clay
SIO-2® Hobby Ceramics clays are especially suitable for beginners in the exciting world of ceramics, as they have a wide firing range between 1000 and 1260ºC.
All the clays contain 40% chamotte, which provides excellent behavior during drying and firing. The range includes two textures of chamotte: ultrafine, for pieces with fine details and a smooth surface, and rough, to work with more complex pieces or pieces with character.
Hobby Ceramics clays are available in white, black and tan brown, after firing.
Because of their extraordinary plasticity, they are also ideal for modelling and sculpture.

ATTENTION: if clay is used to wrap rigid interior supports, it is recommended to first cover the surface with paper or cloth. The water in the clay evaporates during the drying process and causes shrinkage that can lead to cracks. To avoid this negative effect, the solid surface is covered with a flexible and absorbent material to support the drying process of the clay. This will also absorb moisture inside the object and prevent cracks.
ATTENTION: during drying, the clay shrinks (5-7%). The more water the clay contains, the greater its drying shrinkage. Therefore, it is advisable not to add additional water to the clay, otherwise cracks may appear.
ADVICE: let the piece dry on an absorbent surface (ideally wood or plaster). In the case of non-absorbent surfaces (such as metal, plastic or glass), it is recommended to place the piece on a sheet of paper to facilitate the shrinkage of the clay during drying.
The object slightly reduces in size when fired due to firing shrinkage.
ADVICE: in the case of very large, solid or difficult-to-dry pieces, it is recommended to preheat slowly between 150 and 200ºC with the oven door slightly open (not hermetically sealed). This will favor the total evacuation of the drying moisture before firing.

During work interruptions, cover the object with plastic or a damp cloth.
ATTENTION: do not store at temperatures below 0ºC. If clay freezes, it loses its plasticity and becomes brittle.
