Cold Press Porcelain, Cold Porcelain or Porcelanicron is a type of clay that is similar to polymer clay in the sense that it does not require a kiln to be cooked in.  It dries about 24 hours after you've left it out.

This is a rather new medium, said to be originated from Argentina (Porcelana Frķa, Pasta flexible, Masa flexible), however, there is something called bread dough and  cornstarch clay that has been around for a long time and has similar consistency and can be used for the same type of projects.

What I love about this craft is the fine, velvety finish the pieces have.  I had never seen it before, and it's used mostly on ornaments such as dolls, but also for making flowers and flower arrangements (corsages, wedding bouquets and such)
