There seems to be a misconception floating around that cold porcelain clay is completely waterproof. Well, I hate to burst your bubble, but it’s time to set the record straight. Cold porcelain clay is not inherently waterproof. In fact, when immersed in water for an extended period, it can absorb moisture and become soft, losing its shape and structural integrity.

A Matter of Sealing

Fear not, dear reader, for all hope is not lost! Although cold porcelain clay is not waterproof on its own, there is a solution to make your creations water-resistant. The secret lies in sealing the clay properly. By using a sealant or glaze specifically designed for air-drying clays, you can significantly enhance their resistance to water.

The Power of Sealing: Tips and Tricks

To make your cold porcelain clay creations water-resistant, follow these simple yet effective tips:

1. Choose the right sealant

Opt for a sealant that is specifically formulated for air-drying clays like cold porcelain. These sealants are designed to create a protective barrier that helps repel water.

2. Apply multiple coats

A single coat of sealant may not provide sufficient protection. Apply two or three thin coats, allowing each coat to dry completely before applying the next. This will ensure a stronger and more resilient barrier against water.

3. Pay attention to the details

Be thorough when applying the sealant. Pay extra attention to crevices, cracks, and any areas that are more susceptible to water infiltration. Remember, a water-resistant seal is only as strong as its weakest point.

4. Consider additional measures

If you plan on using your cold porcelain clay creations for items that will be exposed to water regularly—for example, a decorative soap dish in your bathroom—you might want to consider additional protective measures, such as using a waterproof varnish or clear epoxy resin.

So, is cold porcelain clay waterproof? In its natural state, no. However, by applying the proper sealant, you can make your cold porcelain creations resistant to water and ensure their longevity. Remember to choose the right sealant, apply multiple coats, pay attention to details, and consider additional measures for items that will be frequently exposed to water. With these tips in mind, you’ll be able to enjoy your cold porcelain clay creations without worrying about them turning into a soggy mess. Happy crafting!
