Getting Started: Tools and Materials
Before diving into specific techniques, let’s gather the essentials. You don’t need a huge investment to begin. The core item is, of course, polymer clay itself. It comes in numerous brands (like Fimo, Sculpey, Kato Polyclay), each with slightly different handling properties and hardness. Experimenting with a few types is often recommended. You’ll also need:- A smooth, non-porous work surface (ceramic tile, glass mat, parchment paper).
- An acrylic roller or, ideally, a dedicated pasta machine for conditioning and creating even sheets.
- Basic cutting tools: a craft knife, tissue blades (flexible and rigid).
- Sculpting tools: These can range from professional sets to simple items like toothpicks, knitting needles, and dotting tools.
- A home oven: Dedicated craft oven is best, but your kitchen oven works if used carefully with good ventilation and cleaning. An oven thermometer is crucial for accuracy.
- Optional but helpful: Clay cutters, texture sheets, mica powders, liquid clay, varnish.
The Foundation: Basic Clay Handling
Mastering a few fundamentals is key before tackling complex projects.Conditioning the Clay
Fresh-from-the-package polymer clay needs conditioning. This process mixes the plasticizers within the clay, making it smooth, pliable, and strong after baking. Unconditioned clay will be crumbly and prone to breaking. You can condition by hand – kneading, rolling, and folding – but this can be tiring. A pasta machine makes quick work of conditioning, passing folded clay through the rollers repeatedly on the thickest setting until it’s smooth and flexible.Mixing Your Own Colors
While clay comes in many colours, you’ll inevitably want a specific shade not available commercially. Polymer clay mixes beautifully. Start with small amounts of the darker or more intense colour and gradually knead it into the lighter colour until you achieve the desired hue. Keep samples of your mixes (baked and unbaked) for future reference.Basic Shapes
Everything starts with simple forms. Practice rolling smooth, even coils (snakes), perfectly round balls without cracks, and flat, uniform slabs using your roller or pasta machine. These basic shapes are the building blocks for almost every polymer clay technique.Techniques for Polymer Clay Jewelry
Jewelry is perhaps the most popular application for polymer clay, thanks to the vibrant colours and intricate patterns possible.Caning (Millefiori Magic)
This is a standout technique where you build a design into a log or block of clay, called a “cane”. When you slice the cane, each slice reveals the same intricate pattern. Think of it like a stick of rock candy. Canes can range from simple stripes and checkerboards to incredibly complex flowers, faces, or geometric designs. Building a cane involves carefully stacking shaped pieces of different coloured clays according to your desired pattern. The cane is then reduced (stretched and compressed carefully) to make the pattern smaller without distorting it. Slices can be applied to beads, pendants, or used as veneers.Mokume Gane Exploration
Inspired by a traditional Japanese metalworking technique, polymer clay Mokume Gane involves layering thin sheets of different coloured clays. Metallic clays often give stunning results. This stack is then distorted by pressing textures or tools into the surface. Finally, thin layers are shaved off the top or sides using a sharp blade, revealing beautiful, woodgrain-like patterns that are unique every time. The results can be unpredictable but always fascinating.The Skinner Blend Gradient
Creating smooth transitions between two or more colours is achieved with the Skinner Blend, named after its inventor, Judith Skinner. This technique requires a pasta machine. You start by placing two or more triangles of clay colour side-by-side and repeatedly folding and passing them through the pasta machine always feeding the fold in first. Gradually, the colours blend in the centre, creating a beautiful, smooth gradient sheet perfect for beads, veneers, and other decorative elements.Surface Treatments and Textures
Beyond colour patterns, adding texture elevates polymer clay jewelry. You can press texture sheets, stamps, lace, leaves, or any found object with an interesting surface onto the raw clay. Mica powders brushed onto the surface before baking add shimmer and iridescence. Chalk pastels shaved and brushed on can provide subtle shading. Liquid polymer clay can be used for drizzled effects, as a “glue” for different components, or mixed with pigments for painting effects.Verified Tip: Always condition your clay thoroughly before attempting complex techniques like caning or Mokume Gane. Properly conditioned clay is more pliable, blends better, reduces cleanly, and results in a stronger finished product after baking. Insufficient conditioning is a common cause of cracking and pattern distortion.
Making Beads and Pendants
Forming beads involves rolling conditioned clay into desired shapes (round, oval, lentil, tube) and piercing holes before baking. For pendants, you can cut shapes from decorated slabs using cutters or a blade, or sculpt them freehand. Remember to create a hole for hanging before baking.Techniques for Polymer Clay Figures
Sculpting figures, from whimsical creatures to realistic miniatures, requires a slightly different approach, focusing on structure and form.Building on an Armature
For anything larger than a very small charm, or for figures with thin limbs, an armature is essential. This internal skeleton provides support during sculpting and baking, prevents drooping, and saves on clay. Armatures are typically made from sturdy wire (like aluminium armature wire) twisted into the basic shape of the figure. Crushed aluminium foil can be bulked out around the wire to create the basic volume before adding clay.Additive Sculpting and Form
Most polymer clay sculpting is additive. You start by covering the armature with a basic layer of clay, establishing the main forms and proportions. Then, you gradually add smaller pieces of clay, blending them smoothly to build up muscles, features, and clothing. Work from large forms to smaller details. Reference images are invaluable here.Creating Details and Textures
This is where figures come alive. Use sculpting tools (ball styluses, needle tools, silicone shapers) to create facial expressions, hair texture, fabric folds, fur, scales, or any other surface detail. Small snakes of clay can become eyelids or lips; tiny balls can form eyes. Patience and a light touch are key.Painting and Finishing Figures
While you can use coloured clay, many sculptors prefer to work in a neutral colour (like grey or beige) and paint the figure after baking. Acrylic paints work exceptionally well on baked polymer clay. You can achieve fine details with small brushes. Once the paint is dry, sealing the figure with a matte, satin, or gloss varnish protects the paint job and gives a finished look.The Crucial Step: Baking Polymer Clay
Baking, or curing, transforms soft clay into hard plastic. Doing it correctly is vital for durability.Temperature and Time are Key
Always follow the manufacturer’s instructions on the clay package regarding temperature and baking time. Each brand differs slightly. Baking too cool results in weak, brittle pieces. Baking too hot can cause burning and release unpleasant fumes. Baking time usually depends on the thickness of the piece (typically 15-30 minutes per 1/4 inch or 6mm thickness).Important Safety Note: Never bake polymer clay at temperatures higher than recommended by the manufacturer. Overheating can release irritating fumes. Always bake in a well-ventilated area. Using a dedicated oven thermometer is highly recommended as oven dials can be inaccurate.
