Joan Miro has innovatively developed super light clay without borax

According to a survey, Joan Miro found that the reports on the hazard of borax have raised consumers’ common concern on safety of crystal mud and clay.

To solve the concern, Joan Miro has innovatively developed foaming microsphere (a thermoplastic hollow high-molecular polymer) which is safe, stable, and more extensible. Based on the material, the company has succeeded in developing super light clay, without any borax, to meet the customers’ safety requirements
