Made in the USA, non-toxic, and ASTM D-4236 certified, it blends easily and accepts multiple paint types for professional-grade finishes.

## Description

What is Cosclay? Cosclay is a hybrid, plastic/rubber polymer clay that remains strong and flexible after curing. Unlike other polymer clays, Cosclay’s unique flexibility imparts a durable and resilient quality that is suitable for endless applications, such as stop-motion characters, posable figures, one of a kind (OOAK) sculptures and much more! Cosclay allows for the creation of very thin and delicate pieces without the fear of breakage after curing, especially during transit. What temperature is best to cure Cosclay to get the optimal properties of the cured clay? It is important to cure at 275°F (135°C) for at least 30 minutes per ¼” of material. If Cosclay is cured at too low a temperature, it will have a weak cure and will break when bent instead of flexing and holding its shape. Because Cosclay is temperature sensitive we do not recommend tabletop plastic dome style halogen convection ovens. Or small tabletop toaster ovens. We find that these types of ovens generate hotspots and uneven heating. While they may work for conventional polymer clays, they do not work well for Cosclay. The best type oven that provides the most even heating is a conventional home oven, either electric or gas. Can I bake my Cosclay, add new Cosclay and bake it again? Will the new clay stick to the cure clay? The answer is yes! You can bake Cosclay repeatedly and new clay will stick to cured clay. How many times can I bake my piece without losing the flexible aspect of Cosclay? Cosclay is formulated to remain flexible after repeated baking. We have baked pieces dozens of times without any noticeable loss of flexibility. Can Cosclay be painted? Yes. Cosclay can be painted with craft acrylics, pastels, Genesis polymer paints and some urethanes. (Test on a small, discreet area for compatibility.) Does Cosclay contain any hazardous components? No. Cosclay is made of 100% nontoxic ingredients. It has been tested by a certified toxicologist and conforms to ASTM D-4236.

Review: Exceptional Performance — Perfect for Detailed Sculpting - Cosclay (Medium Firm Gray) has quickly become my go-to material for serious sculpting projects. I recently sculpted Smaug and chose this clay specifically for its balance of firmness, flexibility, workability, and elasticity after baking—and it absolutely delivered. The medium-firm consistency is ideal for detailed work. It holds crisp textures, sharp edges, and fine sculpted scales without sagging or deforming as you handle the piece. At the same time, it conditions smoothly and blends cleanly, making it easy to refine transitions and build up forms. For a complex subject like Smaug—with layered scales, facial detail, and dynamic anatomy—that stability matters. Out of the package, it does require a bit of conditioning. A short session of kneading helps warm it up and fully activate its workability. After that initial conditioning, it becomes supple, smooth, and cohesive—never dry or crumbly. Once worked, it’s very pleasant to sculpt with and maintains a consistent texture throughout the process. The gray color is also a major advantage. It provides excellent visual contrast for shadows and highlights while sculpting, allowing you to clearly see surface detail and correct imperfections before baking. It photographs well too, which is a bonus if you document your work. After curing, the flexibility of Cosclay really sets it apart from traditional polymer clays. It maintains durability without becoming brittle, which gives added peace of mind on thinner elements or protruding details. That resilience is a game changer for intricate sculpts. (I accidentally dropped this dragon sculpt and nothing broke!) I also believe this product offers excellent value for the money. Considering the performance—both during sculpting and after baking—it competes strongly with other professional-grade polymer clays (better IMO). The added durability post-cure makes it feel like you’re getting more long-term reliability for your investment. It’s also surprisingly approachable for beginners and even kids. The workable texture (once conditioned) makes it forgiving, and the post-bake flexibility adds a layer of durability that’s especially helpful for younger creators who might be a little rough on their finished pieces. Overall, Cosclay is an outstanding choice for serious sculptors and noobs alike. It combines structure, detail retention, and post-bake flexibility in a way that elevates both the sculpting experience and the final result. It handled Smaug beautifully—and I’ll absolutely be using it again for future projects.

It's great!

### ⭐⭐⭐⭐⭐ Amazing clay!
*by L***Y on October 21, 2024*

I LOVE this clay. It is incredibly strong and flexible compared with other oven bake polymer clays I have used. I carved, sanded, added clay and rebaked, and finally painted it. It responded well to all. I also dropped the finished project on the ground more times than I should admit and it did not break.
