Claydium is a fibre-reinforced air-drying modelling clay. It is similar to Newclay but smoother to use and will result in a stronger and harder final dried material. Claydium articles should be finished in the same way as objects made from Newclay. They can be decorated with a good quality ceramic or acrylic paint and finished with Gloss or Satin. Composition: Clay, Water, Nylon, Additives, Preservatives and Pigments. Wheat and Gluten free. Made in England
