Artist's Concrete In partnership with renowned mixed media artist and author Robert Dancik, we are proud to introduce Create Recklessly with Concrete, an innovative yet simple method for making stunning jewelry and original embellishments. While concrete may seem an unlikely material for jewelry, this specially formulated powder creates a final product that is lighter than stone, resin, or metal. Its easy to use: just add water and it sets in minutes, cures in about an hour. Artists Concrete is versatile and strong: pour it, mold it, tint it, and embed it with virtually anything! There are no toxic odors, and the pigments are non-toxic. The concrete itself is a powder, so its advisable to wear a particle mask or similar. Quantity: 8oz (226 grams)
