Our Opinion
In my opinion as a crafting expert, air dry clay is one of the most environmentally friendly modeling clay options available.
t avoids many of the sustainability issues posed by polymer clay or firing clay in a kiln.
Air-dry clay is non-toxic and safe for hobbyists of all ages.
With responsible sourcing of materials, air clay is a great eco-friendly choice for crafters who want to reduce their environmental impact.
What is Air-Dry Clay?
Air-dry clay is a modeling material made primarily from clay and water. Its air dries to hardness instead of requiring kiln firing. The clay in air-dry formulations is often natural, rather than oil-based polymer clay.
Specific ingredients vary between air-dried clay brands but may include baking soda, cornstarch, resin, or other additives. These modify qualities like dry time, strength, elasticity, and texture.
Compared to oil or polymer clays, air dry clays are lower cost, safer for kids, and easier to use right out of the package. But they are less durable.
Air-dry clay dries through evaporation. Over hours or days, the water content evaporates as the clay hardens. Drying time depends on clay thickness and environment.
Once dry, air-dry clay items can be painted with paint and sealed for protection. They are not waterproof unless sealed. Finished pieces are often decorative rather than functional.
While air clay can’t replicate the durability and versatility of ceramics, it provides an approachable, eco-friendly way to create handmade clay items and crafts.
Is Air-Dry Clay an Environmentally Friendly Material?
- Air-dry clay is biodegradable since it’s made from natural clay that breaks down over time. This gives it an advantage over oil-based clays.
- Brands like Crayola Air Dry Clay and Modelena are non-toxic, making air-dry clay safe for kids. No harmful chemicals here.
- You can mix your clay using ingredients like baking soda, cornstarch, and water. DIY clay skips the manufacturing process.
- Some air-dry clay brands are ultra-light, meaning they require less clay overall and save on shipping resources.
- While air clay is better than oil-based clay, it still requires some mining and processing. Using it sparingly is ideal.
So while air dry clay isn’t perfect, it is more eco-friendly than many mainstream craft materials. With mindful use and homemade recipes, it can be a green addition to your crafting routine.
Is Air Dry Clay Biodegradable?
Air-dry clay is generally considered biodegradable and environmentally friendly. Since it is water-based and contains natural clay, it will break down in the environment over time. This makes it a more eco-conscious choice than oil-based polymer clay.
Specific biodegradability depends on the clay recipe. Some air clays contain acrylics or other additives that affect degradability. But the main ingredients – clay and water – are naturally occurring and non-toxic.
After use, leftover or excess air dry clay can be composted. Finished pieces made from air-dried clay will slowly decompose if left outside and exposed to the elements. However, any paint or varnish applied would affect biodegradability.
So while not as “green” as pure natural clay, air clay is gentler on the environment than heavily manufactured and chemical-laden modeling compounds. Its water-based composition and ability to safely break down make air-dry clay a good biodegradable option for crafting.
How is Air Dry Clay Manufactured?
Air-dry clay is made by combining natural clay with an acrylic-based polymer. The clay provides structure, while the polymer acts as a binder.
To start, high-quality clay is mined and refined. Impurities are removed, resulting in a smooth, ultra-fine powder. Separately, the polymer additive is produced through an industrial chemical process.
The clay and polymer are measured out and mixed with water in large industrial mixers. Additional ingredients like colorants or scents may be added. The mixture is blended until homogeneous and a doughy clay texture is achieved.
At this stage, the clay is soft, pliable, and ready for use. It is packaged while still moist to retain its molding properties. The water content allows the clay to be shaped, while the polymer provides flexibility and strength once dry.
By using mined clay and an acrylic binder, manufacturers can produce modeling clay with versatile sculpting qualities. The water-based formula creates a non-toxic, biodegradable product safe for users of all ages. With quality ingredients and precision blending, crafters are provided an eco-friendly air dry clay.

What are the Pros and Cons of Air Dry Clay?
Air-dry clay offers many benefits for crafters and artists. Here are some of the key pros and cons to consider:
Pros:
- Environmentally friendly – Made from natural clay and non-toxic polymers, air dry clay is biodegradable and safe for users. This makes it a great eco-friendly option.
- Easy to use – The clay is ready to mold straight out of the package. It doesn’t require baking or firing, so projects can be completed quickly.
- Versatile – Air-dry clay can be rolled, shaped, cut, stamped, etc. It’s flexible when wet and hardens to a durable finish, allowing for diverse creations.
- Lightweight – Weighing about half as much as ceramic clays, air-dry varieties are ultra-lightweight. This makes projects easier to craft and display.
- Affordable – With accessible price points, air dry clays won’t break the bank. Their lower cost makes experimenting economical.
Cons:
- Delicate when dry – Finished pieces made with air-dried clay are durable but more fragile than ceramic wares. Care must be taken with finished works.
- Surface can stain – Unfinished, unpainted air-dry clay is prone to staining from dirt, oils, etc. A protective sealant is recommended.
- Limited strength – While strong for crafts, air clay lacks the structural integrity for large-scale sculptures or pieces subject to stress.
- Can shrink slightly – A small amount of shrinkage can occur as the water evaporates while air drying. Factor this in when designing.
Overall, air-dry clays offer creative versatility perfect for crafters. Their sculptability, affordability, and eco-friendly qualities make them a great choice. Just keep the finished fragility in mind, and air-dry clay can bring any artistic vision to life!
Is Air-Dry Clay More Eco-Friendly?
Compared to other clays, air- dry varieties are generally considered more eco-friendly and sustainable. This is due to a few key factors:
- Natural ingredients – Air-dry clays are typically made from natural materials like clay, cellulose fiber, cornstarch, baking soda, or non-toxic acrylic polymers. This makes them biodegradable and safe.
- Lower environmental impact – The production of air clay generates less CO2 emissions and industrial waste than firing ceramic clays. Air drying also conserves energy.
- Recyclable – Leftover bits of air-dry clay can be reused by remixing with water. The ability to recycle unused clay reduces waste.
- Non-toxic – Free of chemicals like sulfur, air-dry clays don’t emit fumes or toxins. This benefits both crafters and the environment.
- Accessible materials – Common ingredients like clay, paper pulp, or cornstarch make air varieties more sustainable and renewably sourced.
- Ceramic clays still play an important role in sculpture and pottery. But for crafters and eco-conscious artists, air clays offer a more sustainable alternative. Their biodegradable nature and non-toxic production methods give air clays the edge in eco-friendliness.
FAQ
Is Air-Drying Clay Sustainable?
Air-drying clay is a sustainable option because it is made from natural materials like clay and cellulose. It does not require firing in a kiln which consumes energy. The clay is biodegradable and will break down over time.
What Is the Most Environmentally Friendly Clay?
Natural air-drying clays made from materials like clay, cornstarch, and cellulose are the most eco-friendly options. They do not contain chemicals or plastic polymers. Look for air dry clay brands marked non-toxic.
