Prep the Clay

Proper preparation is key to working with polymer clay. Before sculpting your pins, it’s important to condition and soften the clay. This makes it smooth and pliable, allowing you to roll and shape it more easily.

To condition polymer clay, knead it firmly with your fingers until it becomes soft and malleable. This helps blend the ingredients and brings the clay to an ideal texture for sculpting. If the clay is too firm, you can also run a clay roller over it or pound it with a mallet to soften it up.

Once conditioned, use an acrylic roller or pasta machine to roll the clay into an even sheet at your desired thickness. For pins, a setting of 1-3 cards thick usually works well. You want the clay to be thin enough to bake properly but thick enough to maintain its shape.

Conditioning and rolling the polymer clay adequately before sculpting will ensure your pins hold their shape both before and after baking. Properly prepped clay is easier to manipulate into intricate designs too.

Make the Pins

Now comes the fun part – shaping your polymer clay into decorative pins! There are endless design possibilities when making clay pins. Here are some tips for cutting, shaping, and embellishing your creations:

Cut the conditioned clay into the desired shapes for your pins using cookie cutters, clay blades, or improvised tools like bottle caps. Smooth the cut edges by rubbing with your finger. For dimensional shapes, roll sheets of clay and cut out or use clay extruders and molds.

Texture the clay by pressing in items like lace, mesh, sequins, or stamps. Or create patterns by piercing the clay with tools like toothpicks, skewers, or fork tines. Twist and braid strands of clay for an interesting look.

Embellish further by adding clays eyes, noses, or other details. Brush on specialty clay paints or liquid clay for additional decoration. Insert head pins before baking so the pins are easy to attach later.

Make sure decorative elements are secured well. Use liquid clay to “glue” on any pieces that may fall off. Let the clay dry and harden slightly before baking.

Bake Pins

Properly baking polymer clay pins is crucial for ensuring they are fully cured and durable. The baking temperature and time depends on the type of clay used. Generally, bake the pins at the manufacturer’s recommended temperature (typically around 130°C/275°F) for 15-25 minutes per 6mm of thickness.

For example, a 12mm thick pin should bake for 30-50 minutes. Thicker pins will require longer baking times. When in doubt, it’s better to bake a little longer than required versus not long enough. Under-baked clay will be weak, brittle and could even stay sticky.

Here are some tips for successful baking:

Bake pins in a dedicated oven or toaster oven, not your kitchen oven.
Preheat the oven fully before baking.
Place pins on a baking sheet lined with parchment paper or aluminum foil.
Leave space between pins so they don’t touch.
Avoid overcrowding pins on the baking sheet.
Bake at the manufacturer’s recommended temperature.
Bake for the recommended time based on thickness.
Allow pins to cool completely before handling.

Test doneness by touching the pin gently. Properly cured pins will be hard and not indented. Under-baked pins will still be soft or sticky. Over-baked pins may be scorched or brittle. Adjust bake times as needed if pins don’t pass the doneness test.

Recommended Bake Times

The amount of time needed to bake polymer clay pins can vary greatly depending on the thickness and size of the pieces. Here are some general guidelines for baked times:

Thin/Small Pieces: These are pins that are less than 1/4 inch (6mm) thick at their thickest point. Thin pieces usually need 10-15 minutes in the oven. Very small, delicate pieces may only need 5-10 minutes.

Thicker Pieces: Pins that are 1/4 inch (6mm) or thicker will require longer baking times of 15-30 minutes. Pieces that are 1 inch (2.5cm) or thicker may need 30-60 minutes depending on the brand of polymer clay used.

Always check the manufacturing guidelines for your specific brand of polymer clay for their recommendations on baking times. Follow their advice on baking times based on thickness.

As a general rule of thumb, thicker clay pieces need more time in the oven than thinner pieces to fully cure the clay throughout. Underbaking can lead to pieces that are tacky or brittle, so adhering closely to the manufacturer’s bake time instructions is important.

Test Doneness

The best way to test if your clay pins are fully baked is to use both visual and tactile methods.
Here are some tips:

Visually inspect the pin. It should have an even, matte finish without any sticky or glossy areas. The colors should appear bright and vivid. Underbaked clay will look undercured and pale.

Feel the pin’s surface. It should be completely solid and inflexible. There should be no imprint made when you press on it firmly. Soft spots indicate underbaking.

Check for cracks or scorch marks, which signal overbaking. Properly baked clay is hard but should not show brittleness, chipping, or burn marks.

Perform a drop test. Hold the pin 6-12 inches over a hard surface and drop it. If it cracks or breaks, it is overbaked. A properly baked pin will not shatter.

Test baking a sample piece first to identify the ideal bake time before cooking your final creations. This helps avoid under or overbaking your pins.

Baking Tips

When baking polymer clay pins, using parchment paper versus directly on the oven rack can make a difference. Parchment paper prevents the clay from sticking to the oven rack. It also provides an extra barrier against scorching or burning on the bottom of the pins if the oven runs hot. However, parchment paper can sometimes inhibit airflow around the pins, resulting in uneven baking. The texture of parchment paper may also imprint onto the bottom of soft clay.

Baking pins directly on the oven rack allows for maximum airflow and prevents any imprinting on the bottom. But there is a higher risk of sticking and potential burning. Lightly rubbing the baking surface with cornstarch can help. It’s generally recommended to bake small pins directly on the rack and use parchment paper for larger pieces.

When it comes to the type of oven, a standard full-size oven tends to provide the most even, consistent baking for polymer clay. The confined space and direct heat of a toaster oven can increase the chances of scorching. However, toaster ovens can work well for small batches of pins. Keep a close eye on the pins and rotate the pans periodically for even baking. Lower temperatures and extended bake times are recommended when using a toaster oven.

Finishing Touches

Once your clay pins are baked and have thoroughly cooled, you can apply some finishing touches to give them a polished, professional look. Here are some techniques to try:

Sanding

Lightly sanding your clay pins will smooth any rough edges and remove any imperfections from the baking process. Start with a fine grit sandpaper around 220 and gently sand all surfaces and edges. Be careful not to sand too much or you may remove details.

Buffing

Use a soft buffing wheel or cloth to give your clay pins a nice sheen. Buff them until they feel smooth and have a uniform finish. This will make the colors pop.

Sealing

Applying a sealant will protect the finish of your clay pins and prevent them from absorbing moisture. Use a water-based polyurethane sealant specially formulated for polymer clay. Apply 2-3 thin coats with a soft brush, allowing each coat to fully dry before adding the next.

With these simple finishing techniques, you can give your clay pins a polished, professional look that really makes them stand out.

Troubleshooting

Baking clay pins can sometimes lead to issues like scorching, cracking, or blistering. Here are some tips to help prevent these problems:

Prevent Scorching: Scorching happens when the clay gets too hot and starts to burn or turn brown. To prevent scorching, follow recommended bake times and temperatures carefully. Avoid exceeding the maximum recommended baking temperature as this can cause scorching. Also, check pins regularly during baking to catch any scorching early.

Prevent Cracking: Cracking occurs when clay dries out too quickly and contracts during baking. To prevent cracking, avoid baking clay pins that are too thick, as it takes longer for the inside to dry. Bake pins flat rather than standing up. And avoid increasing baking temperatures to speed up drying, as this shocks the clay. Allow plenty of time for thorough, even drying.

Prevent Blistering: Blisters happen when moisture gets trapped under clay’s surface during baking. To prevent blisters, start with conditioning clay properly and baking at the right temperature. Avoid baking pins that are too thick. And allow clay pieces to air dry completely before baking to release any moisture.

Storing and Caring

To make sure your clay pins retain their shape and color over time, proper storage and care is important.

Store finished pins in a cool, dry place away from direct sunlight. Exposure to light can cause fading over time. An airtight plastic container or resealable bag works well for storage. Lay pins flat or use dividers to separate them so they don’t rub against each other.

Avoid storing pins in very humid environments as moisture can affect the clay. If pins get dusty, use a soft brush to gently clean them. For stuck-on dirt, use a lightly dampened cloth then immediately dry. Avoid soaking pins in water as moisture can seep into the clay and cause swelling or cracking.

When cleaning pins, take care not to scrape or scrub too hard. Clay is durable but can chip if treated roughly. Use a gentle touch when handling to avoid damaging intricate designs.

With proper storage and occasional gentle cleaning, polymer clay pins will last for many years looking as great as the day they were made.
