Polymer clay is a versatile material that is great for creating unique and intricate designs for jewelry, home décor, and more. One of the keys to working with polymer clay successfully is knowing how to properly prepare and bake it. In this guide, we'll cover everything you need to know to avoid common issues like air bubbles, lumps, and cracking when working with polymer clay.
Preparing Your Polymer Clay
Before you begin working with polymer clay, it's important to properly prepare it. Here are the steps to follow:
-
Condition the Clay Conditioning polymer clay means kneading it until it becomes soft and pliable. This is important because it helps to eliminate any air bubbles that may be present in the clay, which can cause issues when baking. To condition the clay, simply take a small piece of clay and knead it between your hands until it becomes soft and easy to work with. Repeat this process with the rest of your clay.
-
Roll Out the Clay Once your clay is conditioned, it's time to roll it out to your desired thickness. You can use a rolling pin or a pasta machine to do this. It's important to make sure that the clay is rolled out evenly and free of any air bubbles or lumps.
-
Create Your Design Now that your clay is rolled out, you can begin creating your design. You can use polymer clay cutters, molds, or your own hands to shape the clay into the desired form.
Common Issues with Polymer Clay and How to Fix Them
Even with proper preparation, issues can still arise when working with polymer clay. Here are some of the most common issues and how to fix them:
-
Air Bubbles Air bubbles can occur in polymer clay if it's not properly conditioned or if it's rolled out too quickly. To prevent air bubbles, make sure to take your time when conditioning and rolling out the clay. You can also use a clay roller to help remove any air pockets that may be present in the clay. If you do notice air bubbles in your clay, use a needle tool or toothpick to gently pop them and smooth out the clay.
-
Lumps Lumps can occur in polymer clay if it's not properly conditioned or if there are pieces of dirt or debris in the clay. To prevent lumps, make sure to condition the clay thoroughly and check it for any debris before rolling it out. If you do notice lumps in your clay, you can use a clay roller to help smooth them out or gently massage the clay with your fingers to remove them.
-
Cracking Cracking can occur in polymer clay if it's not baked properly or if it's baked at too high of a temperature. To prevent cracking, make sure to follow the baking instructions on your polymer clay package. Typically, polymer clay should be baked at around 265-275°F (129-135°C) for 15-30 minutes per 1/4 inch (6mm) of thickness. You should also make sure to properly support your clay during baking to prevent any distortion or warping.
