SIO-2 COLOR PLUS® is coloured natural self-hardening clay. No firing is necessary, achieving great hardness and solidity after drying. Once dry, the clay can be painted with any type of paint or varnish. It can also be polished, carved or drilled. COLOR PLUS is ideal for children's use (4+), being a very suitable material in the development of the creativity skills and plastic expression. It is also ideal for handicrafts. All the clay colours can be mixed, as well as with PLUS clay colours, so that unlimited shades of colour can be obtained without the need to use paints. COLOR PLUS clay has a soft and fine texture to the touch. It is odorless and has very good plasticity for modelling (it can be thrown on a potter's wheel). 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.
