Does Slime Clay Dry Out?
What is Slime Clay?
Slime clay, also known as soft clay or therapy clay, is a modeling clay that has a smooth, soft, stretchy texture similar to slime. Unlike regular clays like pottery clay or polymer clay, slime clay is made to never fully harden or dry out. The main ingredients in slime clay are typically flour, cornstarch, glue, and cream of tartar. These ingredients allow the clay to be moldable and pliable without becoming brittle when dry.
The key differences between slime clay and regular clays are that slime clay is meant to maintain a soft, stretchy texture and it does not harden when left to dry. Regular clays are intended to harden fully when air dried or baked. Slime clays can be dried out but will never cure rock hard. Their flexible, squeezable texture makes slime clays fun to play with and ideal for sensory stimulation.

Does Slime Clay Dry Out?
Like most modeling clays, slime clay can dry out over time if not stored properly. However, slime clay tends to dry out slower compared to other clays due to its polymer-based composition. Here are some key factors that determine if and how fast slime clay will dry out:
Exposure to air – Leaving slime clay uncovered or exposed to open air can cause the clay to lose moisture and become dried out. Storing slime in an airtight container helps minimize air exposure.
Clay ingredients – Slime recipes with more glue and activator tend to dry slower compared to clay-heavy slime. Clay-heavy slimes dry out faster as the clay absorbs moisture from the glue and polymer chains.
Environment/temperature – Warm environments or high temperatures will accelerate drying in slime clay. Storing slime clay in cool, dry places avoids extreme temperature swings.
Handling and reshaping – Frequently handling and reshaping slime clay introduces air pockets and causes moisture loss, drying the clay over time. Minimizing manipulation helps the clay retain moisture.
Signs that slime clay is drying out include the clay becoming stiffer, brittle and cracking easily during shaping. Dried out slime clay feels rough and gritty to the touch versus soft and smooth when wet. The color will appear faded and dull versus vivid when properly hydrated. Bringing dried out slime clay back to life is possible, but preventing moisture loss by proper storage is ideal.
Storing Slime Clay
Proper storage is important for keeping slime clay from drying out. The ideal storage containers for slime clay are airtight plastic containers or resealable plastic bags. According to Wikihow, squeezing out excess air and sealing slime clay in an airtight plastic bag or container helps keep it moist and prevents it from drying out (https://www.wikihow.com/Store-Slime). Small reusable containers, labeled and organized in a craft cart or storage box, also work well for storing slime clay supplies according to Cuckoo4Design (https://cuckoo4design.com/how-to-organize-your-slime-supplies/).
Slime clay can be stored for weeks or even months if properly sealed and kept away from air, heat, and light. The ideal temperature for storage is around room temperature. Storing slime clay in the refrigerator can help extend its shelf life, but freezing is not recommended as it may permanently alter the clay’s texture and properties once thawed.
Checking regularly on stored slime clay and remixing any dried sections will also help maximize its usable lifetime. With proper storage, most slime clay should remain moist and workable for at least 4-6 weeks when sealed in an airtight container at room temperature.
Reviving Dried Out Slime Clay
If your slime clay has dried out and become hard, don’t throw it away just yet! There are some simple tricks you can try to rehydrate and revive the clay.
The most common method is to add a few drops of water or oil and knead the clay vigorously with your fingers. Start with just a few drops, as you don’t want to oversaturate the clay. Knead for a few minutes to work the moisture throughout the clay and restore its sticky, pliable texture.
You may need to repeat this process several times, adding more liquid in small amounts and continuously kneading, until the slime regains its original consistency. Be patient and keep working the clay – it can take some time and elbow grease to rehydrate properly.
If the slime clay has hardened and cracked extensively, it may be too far gone to revive. At this point, even with kneading and moisture, it won’t be able to bind back together into a smooth, workable clay.[1] You’ll know it’s time to discard and replace the clay if it remains crumbly and won’t hold its shape after repeated attempts to rehydrate.
Preventing Slime Clay From Drying
There are a few simple ways to help prevent slime clay from drying out prematurely:
Use an airtight container. Storing slime clay in an airtight container or ziplock bag will help seal in moisture and prevent it from drying out. Make sure to press out any excess air before sealing the container.
Add oils or cream. Adding a few drops of oil like coconut oil, baby oil, or mineral oil can help keep slime clay soft and moist. You can also mix in a bit of lotion, cream, or moisturizer.
Store away from heat/sunlight. Keeping slime clay away from direct sunlight or heat sources like right next to a window, heater, or stove may cause it to dry out faster. Store in a cool, dark place instead.
Check on it periodically. Even with proper storage, slime clay can still slowly dry over time. Occasionally check it and re-moisten as needed to maintain the right consistency.
Slime Clay vs Air Dry Clay
Slime clay and air dry clay are two different types of modeling clay that have some key differences in their ingredients and properties.
Slime clay is made from a soft, pliable polymer that allows it to retain its moisture and flexibility even when left uncovered for long periods. It typically contains ingredients like silicone putty, plasticizers, and foam beads. Some popular brands of slime clay include Crazy Aaron’s Thinking Putty and Cloud Slime.
In contrast, air dry clay is made from natural materials like clay and cellulose. When exposed to air, the moisture in air dry clay evaporates over time, causing it to harden and become brittle. Popular brands of air dry clay include Crayola Model Magic and ACTIVA Air Dry Clay.
A key difference is that slime clay will not harden or dry out like air dry clay. This makes slime clay better for projects requiring a permanently flexible, moldable clay. However, air dry clay can be painted and decorated after drying, so it’s preferred for detailed sculptures. Air dry clay also tends to be more affordable than slime clay.
In summary, slime clay retains its putty-like texture while air dry clay will harden when left uncovered. Slime clay is best for play and reusable projects, while air dry works better for decorative crafts. Know the difference between the two when selecting the type of clay for your needs.

Slime Clay vs Polymer Clay
Slime clay and polymer clay are often confused, but there are some key differences between the two clays.
The main difference is that polymer clay does not dry out like slime clay does. Polymer clay remains flexible and workable even when left in open air. Slime clay, on the other hand, will gradually harden and dry out when exposed to air over time. [1]
Another major difference is that polymer clay requires baking to cure and harden it. The clay polymers cross-link when baked at the proper temperature to create a permanent, durable material. Slime clay does not require baking and will air dry on its own.
Additionally, polymer clay typically does not stick to hands and is easy to work with. Slime clay is stickier and requires coating hands with cornstarch or oil to prevent sticking. Polymer clay has a smooth, non-sticky texture even without additives.
In summary, the key distinctions are that polymer clay remains flexible, requires baking to cure, and has a non-sticky texture, unlike slime clay which dries out, air dries, and is stickier to handle.
