The advantages of ‘Peacock’ over other brands are: It is non-sticky, easily washable and does not dry or granulate for as long as 18months. It is the only clay to have been certified “Non-Toxic” by the Indian Institute of Toxicology, Pune. As compared to Play Dough, "Peacock" has more working life and better malleability. Dough being organic material ferments and is prone to fungal growth within 45 to 60 days which can prove toxic for children. It also becomes hard and dry within a short period. "Peacock" clay is available in attractive bright colors which can be mixed to create more super colors.
