Air-Dry Clay – synthetic clay-like substance. It is NOT the same material as regular Polymer Clay. Some (but not all) polymer clay techniques may be used for air-dry clay, but the main difference is that air-dry clay shall be allowed to dry, and it shall not be baked. Lots of new techniques specific to air-dry clay were developed recently.
Antique – originally, something made in an early period and valuable. Antique pieces usually have some sort of Patina on them, which was formed over the years. This patina may highlight details on a sculptural piece in an interesting way, making it a desirable effect. To antique a new item, artificial patinas are applied. For polymer clay, such patinas may be formed using acrylic paints. Example of antiqued details on a sculpted vase. Also see Patina.
Appliqué – originally, a technique when pieces of fabric are sawn onto a foundation piece of fabric. For polymer clay, it is a technique when pieces of polymer clay are attached to any foundation (including polymer clay itself) or when other materials are applied to polymer clay surface. Examples include application of slices of polymer clay canes, formation of filigree, or metal leaf application. Example of a pendant with metal leaf. Also see Onlay.
Armature – an internal structural support for a sculpture. The armature could be made out of wire, foil, paper, or other materials. It is widely used with polymer clay to add strength to sculpted pieces and to reduce the amount of clay needed for sculpting (big polymer clay beads, for example, may be formed around balls made out of aluminum foil). Armature may be permanent (left in the clay sculpture) or temporary (removed after baking). See also Light Bulb Vessel.
Art Clay Silver (ACS) – a brand of PMC (Precious Metal Clay).
Baking – for polymer clay, it is a process of curing it. Tutorial about baking polymer clay.
Bargello – originally, a type of needlepoint embroidery which consists of upright flat stitches. The name originates from a collection of chairs from Bargello palace in Florence, Italy. For polymer clay, it is a technique imitating the bargello style embroidery.
Bead Roller – tool used to make uniform beads. This tool usually consists of two pieces of half-tube that can be interlocked. A bead is formed by sliding these two pieces against each other. Picture of a bead roller.
Blade – long sharp strip of metal used for cutting. Examples of blades used for polymer clay.
Brayer – a small hand roller, typically used in printmaking techniques to spread ink. They can be made of rubber, sponge, or plastic. It is used by PC artists to smooth out paper on polymer clay (for paper transfer technique). For most applications, it may be substituted with a regular Roller. Alternatively, any long object with smooth surface (such as a ruler) my be used as a brayer.
Buffing – Polishing, putting a high gloss on a surface by repetitive circular motions. For polymer clay, it is usually the next step after Sanding. Polymer clay objects may be buffed using a buffing machine, a modified bench grinder, a Dremel with a buffing wheel attachment, or manually. Buffing is one of the ways to finish a polymer clay object. Tutorial about finishing polymer clay creations.
Cane (caneworking) – originally a technique used by glass blowers. A cane is made from rods of glass melted together to form a design that can be revealed when a cane is sliced. A cane may be reduced, which allows creating intricate designs with many details. Slices of cane are applied to a surface to form a pattern. The same technique is now used for polymer clay. Example of a bracelet decorated with cane slices. Also see Millefiori.
Carving – cutting solid material (wood, stone, cured or raw polymer clay) into a special shape by removing small pieces of it with carving tools. Usually similar or the same tools are used for carving all of these materials.
Cernit – a brand of Polymer Clay available in many colors, including those imitating stones. It is one of the strongest clays, comparable to Kato. Available in specialized stores and on line. Tutorial about different brands of polymer clay.
Clay Gun – Extruder, a tool similar to a syringe. It is usually equipped with series of interchangeable disks that allow forming different designs by pushing polymer clay through them. Picture of a clay gun.
Clay Softener – a special diluent designed to aid in Conditioning of polymer clay that is too stiff to work with. May be substituted with Liquid Clay. Tutorial about conditioning polymer clay.
Cloisonné – an ancient metal-working technique when cloisons (French for cells) are formed using wire soldered onto metal surface and filled with glass enamels. Picture of a faux cloisonné pendant (see more pictures throughout the site). Tutorial for Eugena's faux cloisonné technique.
Conditioning – making polymer clay more pliable by mixing, kneading, or rolling it. Tutorial about conditioning polymer clay.
Covering – for polymer clay, it is a technique involving layering sheets of polymer clay or polymer clay details over an object such as box, egg, vessel, pen, etc. Objects may be covered completely or partially. Example of a glass vase covered with polymer clay.
Crackling – a technique of creating cracks on the surface (generally, on the surface of paint or glass). When working with polymer clay, this effect may be created using acrylic paints or metal leaves. Picture of earrings with crackled metal leaf effect.
Curing – see Baking. Tutorial about baking polymer clay.

Mokumé Gané – originally a metal-working technique developed in 17-th century Japan, producing a metal surface with distinctive layered patterns. Mokume gane translates as wood eye metal. Adopted for polymer clay, this technique involves stacking layers of clay, distorting them, and then taking slices off the hills and valleys to reveal the different layers. A variation of this technique requires ripple blade. Metal leaf inclusions may be used to further emphasize layers of polymer clay. Picture of a pendant and earrings made using mokume gane technique.
