Making modelling clay soft primarily depends on the type of clay you are working with. Different clays respond best to different methods, but warmth and moisture are key components for most.
Methods to Soften Various Types of Modelling Clay
To effectively soften your modelling clay, identify its type first. Below are the most common methods tailored for different modelling clay compositions.
1. For Water-Based Modelling Clays (e.g., Air-Dry Clay, Pottery Clay)
If your modelling clay is water-based and has hardened due to evaporation, reintroducing moisture is the most effective approach. This method is particularly useful if the clay is relatively soft but has started to stiffen.
- Poke Holes: Begin by poking several holes into the clay using your finger or a tool. This creates channels for water to penetrate deeply.
- Add Water: Carefully pour a small amount of water directly into these holes. You can also add a little water around the exterior of the clay. The goal is to moisten the clay without saturating it.
- Re-Wrap and Rest: Once water has been added, wrap the clay tightly back in its original plastic packaging or in an airtight container. Allow it to sit for several hours, or even overnight. This gives the moisture time to absorb evenly throughout the clay. Knead the clay after resting to check its consistency and distribute the moisture. Repeat if necessary, adding small amounts of water each time.
2. For Polymer Clay (e.g., Sculpey, Fimo, Premo)
Polymer clay softens with warmth and manipulation. It doesn't dry out like water-based clays but becomes firm over time or in cool environments.
- Manual Kneading: The simplest method is to break off a small piece and knead it repeatedly with your hands. The warmth from your hands will gradually soften the clay.
- Warmth Application:
- Body Heat: Place the clay in your pocket for 10-15 minutes, or sit on it (wrapped, of course) for a short period.
- Heat Lamp/Warm Surface: Place the clay under a low-wattage heat lamp or on a heating pad set to a low temperature for a few minutes. Monitor closely to prevent baking or melting.
- Hair Dryer: Briefly apply low heat from a hair dryer. Keep the dryer moving to avoid overheating one spot.
- Clay Softeners/Conditioners: For very stiff polymer clay, special liquid clay softeners (available from craft stores) can be kneaded into the clay. Start with a tiny drop and add more gradually until the desired consistency is reached.
- Mixing with Fresh Clay: Kneading a small amount of stiff clay with a piece of fresh, soft polymer clay can help transfer some of its pliability.
3. For Oil-Based Modelling Clay (e.g., Plasticine, Plastilina)
Oil-based clays, also known as non-hardening clays, become stiff in cold temperatures. They primarily soften with warmth and kneading.
- Manual Kneading: Similar to polymer clay, continuous kneading generates friction and body heat, making the clay more pliable.
- Warm Environment:
- Sunlight: Place the clay in a sealed bag in a sunny spot for a short time.
- Warm Room: Simply leaving the clay in a warm room can help.
- Warm Water Bath (Indirect): Place the clay in a sealed plastic bag and submerge the bag in a bowl of warm (not hot) water for 5-15 minutes. Ensure no water gets into the clay.
Quick Reference Guide for Softening Modelling Clay
| Clay Type | Primary Softening Method | Tips & Tools |
|---|---|---|
| Water-Based Clay | Reintroduce moisture | Poke holes, add water, re-wrap tightly, allow to absorb. |
| Polymer Clay | Warmth and kneading | Manual kneading, body heat, heat lamp (low), clay softeners, mix with fresh clay. |
| Oil-Based Clay | Warmth and kneading | Manual kneading, warm room/sunlight, indirect warm water bath (in sealed bag). |
Tips for Maintaining Modelling Clay Softness
- Store Properly: Always store modelling clay in airtight containers or plastic wraps when not in use. This prevents water evaporation for water-based clays and protects all types from dust and debris.
- Keep Away from Extreme Temperatures: Avoid storing clay in very cold or very hot places. Moderate room temperature is ideal for most types.
- Condition Regularly: For polymer and oil-based clays, occasionally kneading them, even if not for a project, can help maintain their flexibility.
By understanding the composition of your modelling clay, you can apply the most effective method to restore its soft, workable consistency.
