To make air dry modeling clay softer, you can add liquid to the hardened clay and allow it to absorb over time.
A practical method involves placing the hard clay in a bag, adding a small amount of liquid (commonly water), shaking the bag to distribute the liquid, knotting or sealing the bag, and then letting it sit, ideally for a day.
Step-by-Step Guide to Soften Dry Clay
Reviving hard air dry clay requires reintroducing moisture gradually. Here’s a common and effective technique:
- Gather Your Supplies: You will need the hard air dry clay, a resealable plastic bag or container, and some water.
- Break Up Large Pieces: If the clay is very hard and in a large block, break it into smaller pieces if possible. This helps the moisture reach the core more easily.
- Place Clay in Bag: Put the pieces of hard clay into a sturdy resealable plastic bag.
- Add Liquid: Add a small amount of water to the bag. Start with just a few drops or a teaspoon, depending on the amount of clay. You can always add more later if needed. Adding too much water initially can make the clay overly sticky or mushy.
- Distribute Moisture: Seal the bag and shake it gently to help the water make contact with the clay surfaces.
- Seal and Wait: Knot or securely seal the bag. The goal is to create a humid environment where the water can slowly penetrate the clay.
- Allow Time for Absorption: Leave the sealed bag undisturbed for a period. The reference suggests leaving it for a day. During this time, the water will gradually soak into the clay.
- Check and Knead: After waiting, open the bag and check the clay. It should feel softer. Take the clay out and begin to knead it. Kneading helps to evenly distribute the moisture that has been absorbed, bringing the clay back to a workable consistency.
- Repeat if Necessary: If the clay is still too hard, you can repeat the process by adding a few more drops of water, sealing the bag, waiting, and kneading again.
This method relies on giving the clay ample time to absorb the added moisture in a contained environment, effectively reversing the drying process.
