What is Cold Porcelain?
Cold porcelain is a type of modeling clay that is air-dried and does not require baking or firing. It is made from a combination of cornstarch, white glue, and mineral oil, and sometimes other additives like glycerin or vinegar to enhance its properties.
Unlike traditional porcelain clay, cold porcelain is not actually made from porcelain minerals and does not require high temperatures to harden. It is a versatile and pliable material that can be molded into various shapes and designs. Once dry, cold porcelain has a smooth and porcelain-like finish.
Due to its composition, cold porcelain is lightweight and easy to work with. It can be colored using acrylic paints or pigments, allowing for a wide range of color options. Cold porcelain is commonly used for making small figurines, jewelry, flowers, and other decorative items.
Pro Tip: When working with cold porcelain, make sure to keep it covered or wrapped in plastic when not in use to prevent it from drying out. If the clay becomes too dry or stiff, you can add a small amount of mineral oil or glycerin to soften it.
What is Polymer Clay?
Polymer clay is a type of modeling clay that is composed primarily of PVC particles. It is a versatile material that can be molded and shaped into various forms. The clay is soft and pliable, making it easy to work with. It does not dry out or harden on its own and requires baking to cure. Polymer clay is often available in a wide range of colors and can be mixed to create custom shades.
One of the advantages of polymer clay is its durability. Once it has been properly cured, it becomes quite strong and can withstand normal wear and tear. Polymer clay can also be sanded, buffed, and polished to achieve a smooth and finished appearance.
When choosing polymer clay, it is important to consider the specific project you will be working on. Different brands and types of polymer clay may have varying levels of hardness and flexibility, which can affect the final result. It is also essential to follow the manufacturer’s instructions for baking and curing the clay, as improper baking can result in brittle or unstable pieces.
Comparison of Cold Porcelain and Polymer Clay
When it comes to working with cold porcelain and polymer clay, there are distinct differences to consider. Let’s take a dive into this comparison and explore the material composition, texture and workability, drying and curing process, strength and durability, color options, as well as finishing and sealing techniques. Whether you’re a seasoned artist or just starting out, understanding these variances will surely help you make informed decisions for your next creative project. So, let’s dig in and discover the exciting world of cold porcelain and polymer clay!
