Understanding Polymer Clay
Polymer clay is a type of modeling clay that is made from a combination of PVC resin and a liquid plasticizer. Unlike traditional clay, polymer clay is not air-dried or kiln-fired. Instead, it hardens when cured at a specific temperature.
The Curing Process
To harden polymer clay, it needs to be properly cured. The curing process involves heating the clay in an oven at a specific temperature and for a designated time. This process allows the molecules in the clay to bond, resulting in a solid and durable finished product.
Why Does Polymer Clay Harden
The hardening of polymer clay is a chemical reaction that occurs when heat is applied. When the clay is heated, the plasticizer evaporates, and the PVC particles in the clay fuse together. This fusion creates a solid and rigid structure.
Can Polymer Clay Harden Without Heat
One common misconception is that polymer clay can harden just by leaving it exposed to air. Unfortunately, this is not the case. Unlike air-dry clay, polymer clay requires an external heat source to cure properly.
The Importance of Proper Curing
Proper curing is essential to ensure that your polymer clay creations achieve their maximum strength and durability. If the clay is not cured at the correct temperature or for the right amount of time, it may result in a weak and brittle finished product.
