Concrete in Jewelry

July 29, 2013

An industrial material such as concrete seems unlikely for jewelry, but it works very well! It is relatively lightweight, and very durable. It is great for personalized adornment, because you can embed virtually any charm, bead or found object you want.

Difference Between Cement and Concrete

Cement is a powdered ingredient (mostly calcium silicates) used in concrete. It is strong, but brittle and susceptible to scratching. When mixed with water, it undergoes a series of chemical reactions and slowly crystallizes into a strong, interlocking form. Concrete is a mixture of cement, an aggregate (sand or gravel) and water.

Tips on Using EnCapture Artisan Concrete

Storage of the product is critical. Extreme temperatures may affect the mixture or compound, and can jeopardize the integrity of the activator liquid. For best results store in a dry, cool location and don’t freeze. Keeping the compound dry is essential; once moisture is introduced the chemical reaction starts. Store products in closed containers. The shelf life, when stored properly, is one year (if not longer).

Coloring Concrete

Prismacolor colored pencils can be used to color the surface of concrete! To prepare the surface, wet-sand it using fine-grit, wet/dry sandpaper and let dry for 24 hours. To seal the color, spray with several light coats of Krylon UV sealant.

Safety When Using Concrete in Jewelry

Always use disposable cups and utensils. Throw away unused concrete; do not wash it down the drain (it will clog pipes). Wear a respirator, safety glasses and gloves.
