No Baking (Air-Dry): It dries in the air without needing to be baked. It is easy to mold, even by children. The constructions are not as strong as those made with polymers and may be damaged by heat and water.
Polymeric: It remains elastic until it is baked at low temperature. When taken out of the packaging, it needs to be worked to soften. It offers a waterproof and stronger result compared to the classic one. It is ideal for constructions that require details.
