Natural Self-hardening Clay
SIO-2 PLUS® is natural self-hardening clay. No firing is necessary, achieving high hardness, strength and solidity after drying. Once dry, the clay can be painted with any type of paint or varnish. It can be also polished, carved or drilled.
Recommended for handicrafts and professional crafts, as well as children's use (4+).
PLUS clay has a soft, pleasant and fine texture to the touch. Its natural clay composition gives it excellent plasticity for modelling making very fine details. Can also be thrown on a potter's wheel. Odorless and does not stain. Clay residue can be easily removed from any surface with a damp cloth. The presence of natural cellulose fibers allows safe drying without cracks or fissures, even in large pieces.
Conforms to European EN-71 and USA (AP non-toxic product) regulations. Does not contain food allergens.

How to use it

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. The more water the clay contains, the greater its drying shrinkage. Therefore it is advisable not to add additional water to the modelling clay, otherwise cracks may appear.
TIP: 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 contraction of the clay during drying.
ATTENTION: SIO-2 PLUS® clay is not waterproof. It is not advisable to create objects that come into contact with water (vases, pots, cups, etc.) even if they are protected with a waterproofing agent. In this case, we recommend using an inner container made of plastic or glass, so that the piece of SIO-2 PLUS® is only for exterior decoration. In this context, keep in mind the last point of "Working with clay".
During work interruptions, cover the object with plastic or a damp cloth.
ATTENTION: keep the product in a cool environment, avoiding high temperatures. Do not store at temperatures below 0ºC. If the clay freezes, it loses its properties.
In relation to other air-drying clays, SIO-2 PLUS® is composed of minerals and natural clays, with plasticity noticeable at touch, but especially it is recognizable by the lack of smell. Unlike other self-hardening clays on the market, SIO-2 PLUS® clay can be thrown on a potter’s wheel.
It must be taken into account that, when firing, the object significantly reduces its dimensions (firing shrinkage). In addition, during the firing of SIO-2 PLUS® clay, smoke is generated from the combustion of organic matter. The smoke gives off an unpleasant odor and appears from 130ºC. In the case of firing SIO-2 PLUS® clay, the area must be sufficiently ventilated or a good system for evacuating the kiln fumes must be provided.
