Sio-2 Plus® Self-Hardening Modeling Clay, 1.1 lb (500 g)

PLUS Clay is a premium quality, natural, self-hardening clay.  Its exceptional plasticity and ultra fine grade allows for excellent detail and versatility.  It air cures to superior strength and durability (will not crumble when dry), with minimal shrinkage. PLUS Clay can be carved, sanded, and drilled when dry, and it will accept virtually any finish. It is a suitable material for the development of creative skills and plastic expression. This is a clay that is perfect for artists.

SIO-2 PLUS® clay has a soft, pleasant and fine texture to the touch. Can also be thrown on a potter's wheel. Odorless and not staining. The rest of the clay 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.

This clay conforms to the European regulation EN-71 and to USA regulation (seal AP non toxic product). It does not contain food allergens.

PLUS Clay with a thickness of 1/4 inch will take approximately 24 hours to dry. Drying times will vary depending on the thickness of your piece and the amount of humidity in the air.

How to use SIO-2 PLUS® Clay

  • Very clean handling.
  • Use a cutting wire to slice enough clay to work with.
  • It is recommended to knead the claySIO-2 PLUS®before working with it.
  • If clay loses its plasticity during modelling, just slightly moisten your hands to recover it.
  • The clay is easy to model, using adequate modelling tools. It can also be moulded (we recommend plaster moulds) and thrown in a potter’s wheel. Solid or very thin-walled objects can be made with optimal results.
  • To get an even surface, use a wooden roller and two slats of the same height.
  • A large wire-loop tool is used to extract large pieces of excess clay and to shape; for example, a bowl.
  • A double-face wire-loop tool is used to remove small leftover clay and refine details.
  • To join two pieces of clay together, previously scratch the parts to be joined with a spatula or awl and with a brush moisten them with slip (clay previously mixed with water until a liquid texture is obtained). In the case of corner-shaped joints, reinforce the joint with the help of a noodle of clay along the angle and then press and smooth the joint with a spatula.
  • To join two dry pieces, use conventional glue. It is not recommended to join a dry part with a wet part, as the union would crack due to shrinkage during drying of the wet part.
  • A wooden rib helps to remove small imperfections on flat surfaces.
  • A metallic rib is used to smooth out small imperfections on curved surfaces.
  • To smooth and polish surfaces to a very clean finish, use a damp sponge.
  • For modelling hollow items, flexible supports can be used.
