Frequently Asked Polymer Clay Questions
What is special about polymer clay?
Polymer clay is unique because it is a versatile, oven-bake modeling material made from synthetic polymers. It stays pliable until baked, allowing for intricate designs and fine details. It comes in a variety of colors, can mimic materials like stone, metal, or wood, and is widely used for crafts, jewelry, and art projects.
Why does my polymer clay break so easily? Polymer clay can break easily if:
- It is underbaked; baking at the wrong temperature or not long enough can weaken its structure.
- It was rolled too thin without reinforcement.
- Poor-quality clay or expired clay was used.
- It was not conditioned properly before use, leading to uneven texture.
How long can polymer clay sit before baking?
Polymer clay can sit indefinitely before baking as it does not dry out in the air. However, dust and dirt can accumulate on it over time, so it’s best to cover or store it properly until you are ready to bake.
What is the best surface to work with polymer clay?
The best surfaces for working with polymer clay include:
- Glass or ceramic tiles: Non-porous and smooth, ideal for rolling and cutting.
- Non-stick silicone mats: Prevent sticking and are easy to clean.
- Marble or granite countertops: Provide a cool surface to work on, which can prevent clay from becoming too soft.
Avoid porous or textured surfaces as they can absorb oils from the clay or transfer unwanted textures.
What are some unique facts about clay?
- Clay has been used for thousands of years in pottery, construction, and art.
- Polymer clay, unlike natural clay, is made of PVC (polyvinyl chloride) and plasticizers.
- It does not require a kiln; a regular oven suffices for curing.
- Clay particles are negatively charged, which is why they bind together so effectively.
What are the disadvantages of polymer clay?
- Fragility: Improperly baked pieces can be brittle.
- Toxicity concerns: It releases fumes if overheated or burned.
- Softening issues: It can become too soft and difficult to work with in warm environments.
- Environmental impact: As a plastic-based material, it is not biodegradable.
- Storage sensitivity: It can react with certain plastics and leach oils if not stored properly.
What makes polymer clay harden?
Polymer clay hardens through a process called polymerization, which occurs when it is baked at the recommended temperature (usually between 265°F and 275°F or 129°C–135°C). The heat activates the particles in the clay, causing them to fuse together and form a solid structure.
What is the best and most durable polymer clay to use?

How to prevent bubbles in polymer clay?
- Condition the clay thoroughly: This eliminates trapped air pockets.
- Roll the clay properly: Use a pasta machine or acrylic roller to flatten it evenly.
- Pierce large areas: Use a needle to gently pop visible air bubbles before baking.
- Bake properly: Avoid sudden temperature changes in the oven that can cause air pockets to expand.
- Layer carefully: Press out air pockets when combining layers of clay.
Tip: To remove excess oil from clay, you can leach it by placing the clay between two pieces of paper. This is often needed for new batches of clay.
Is Polymer Clay Safe for Kids?
Yes, polymer clay is generally safe for kids when used as directed. Brands like Du-kit, which is New Zealand-made and non-toxic, are a great option. However, it’s important to supervise young children during use, as polymer clay is not edible and should be baked according to the manufacturer’s instructions. Always check the product packaging for specific safety guideline.
Can You Paint on Polymer Clay?
Yes, you can paint on polymer clay! For best results, use acrylic paints after the clay has been baked and cooled. Make sure the surface is clean and dry before painting. For added durability, seal your painted design with a compatible varnish or sealer. Avoid using oil-based paints, as they may not adhere well to the clay.
Can Polymer Clay Get Wet?
Yes, baked polymer clay is water-resistant, so it can get wet without being damaged. However, it is not completely waterproof, and prolonged exposure to water may weaken any paint or sealant applied to the surface. If your project will be exposed to water frequently, consider sealing it with a waterproof varnish for added protection.
Here’s a note addressing whether polymer clay can dry without baking:
Can Polymer Clay Dry Without Baking?
No, polymer clay does not air-dry. It stays soft until it is cured through baking at the correct temperature specified by the manufacturer. Baking is essential to harden the clay and make it durable. If baking isn’t an option, consider using air-dry clay as an alternative.
