Cold porcelain is a sort of air-dried clay. Unlike classic "hot" porcelain it doesn't require being baked in the oven. It hardens on its own once it is exposed to air. The items you get, however, are not fragile. On the contrary, they are very flexible and elegant. Petals can be folded, and the stems can be bent.

Polymer clay is available in hand-made and art related stores. It is usually sold in packs of 150 to 200 grams (5-7 oz). It is naturally a whitish material that gets greyer when it dries up. In order to make items of different colors the clay is mixed with oil paints or dry dyes. Some items could also require some toning with paints or soft pastel.
