Frequent question: Will polymer clay harden without baking?
Frequently asked question: Will polymer clay harden without baking? The answer is no, polymer clay requires baking in an oven to cure and harden. While some clay brands may claim that air-drying is sufficient for certain applications, it’s essential to note that air-drying polymer clay will not achieve the same level of hardness, durability, or color saturation as clay that has been baked. The baking process also allows the clay to reach its full strength and prevents it from cracking or warping over time. So, if you want to create long-lasting, high-quality polymer clay projects, be sure to follow the manufacturer’s recommended baking instructions.
What happens if you dont bake polymer clay?
If you fail to bake polymer clay, the end result will not be a solid and durable sculpture or figurine as you may have anticipated. Polymer clay is a synthetic material that is moldable and malleable when soft, but it must be cured through baking in an oven at a specific temperature to harden and maintain its shape. If you skip this crucial step, the clay will remain pliable and unchanged, making it prone to deformation, tearing, and breaking easily. It will not be able to withstand any form of pressure or weight, and will likely crumble or cracks when touched. Furthermore, the clay will not retain its color or texture, and may fade or discolor over time due to exposure to air and light. In short, failing to bake polymer clay will result in a subpar, unfinished product that lacks the desired strength, durability, and artistic value.
