How Do You Keep Polymer Clay From Sticking To Cookie Cutter?

ByScarlett Evans

Introduction to Polymer Clay

Polymer clay is a modeling and sculpting material that has become wildly popular in recent years for arts and crafts. Made from PVC resins and plasticizers, polymer clay maintains its shape after being molded, allowing it to be hardened in a regular oven at home. Its versatility and ease of use have made polymer clay a favorite for jewelry, figurines, ornaments, dolls, and more [1].

However, a common frustration arises when using cookie cutters or other tools to cut shapes and designs. The soft clay often sticks inside the cutters, requiring tedious clean-up and damaging intricate cookie cutter patterns [2]. This guide will provide tips to prevent sticking and keep cookie cutters clean when working with polymer clay.

Preparing the Work Surface

When working with polymer clay, it’s important to prepare your work surface properly to prevent the clay from sticking. Here are some tips for getting your work area ready:

Use parchment paper or wax paper as your work surface. Lay it down on your work table or countertop before beginning. Polymer clay won’t stick readily to parchment or wax paper, so you can easily lift your clay creations off without deformation [1].

Try working on a smooth ceramic, glass, or polished metal surface. Smooth glossy surfaces like these help prevent polymer clay from adhering [2]. Make sure to clean the surface thoroughly first.

Lightly dust your work surface with cornstarch or talcum powder. These powders make it harder for the clay to stick. Brush off any excess before baking.

Avoid porous materials like untreated wood, cardboard, or fabric. Polymer clay can grab onto the tiny grooves and indentations, making it hard to lift off afterwards.

Use silicone baking mats with a smooth finish. The nonstick surface resists bonding with the clay.

Prepare your tools like rollers and cutters the same way. Lightly dust with cornstarch or lay parchment paper underneath to keep clay from clinging.

Choosing the Right Cookie Cutters

When working with polymer clay, it’s important to choose cookie cutters made from materials that reduce sticking. Metal and plastic are the most common materials for cookie cutters. Both have pros and cons when used with polymer clay:

Metal cookie cutters are durable, hold their shape well, and create clean cuts in clay. However, raw metal can easily stick to polymer clay. Stainless steel resists sticking better than other metals. Copper and aluminum are very prone to sticking.

Plastic cookie cutters are inexpensive and come in endless shapes. Smooth plastics like acrylic and polycarbonate resist sticking. Textured plastics grip the clay more. Release agents help plastic and metal cutters slide more smoothly through clay.

According to Etsy, some top materials for polymer clay cookie cutters are:1:

  • Stainless steel
  • Acrylic
  • Polycarbonate
  • Silicone

Avoid copper, aluminum, and highly textured plastics when possible. Opt for smooth, non-stick surfaces for clean cutting and releasing.

Applying release agents is an effective technique to prevent polymer clay from sticking to cookie cutters and molds.

Applying Release Agents

There are several common household items that can be used as release agents when working with polymer clay (according to Polymer Clay & Release Agents). These include:

  • Cornstarch – One of the most popular release agents, cornstarch can be dusted directly onto the cookie cutter before pressing in the clay.
  • Water – Wiping cookie cutters with a damp paper towel or cloth creates a barrier to keep the clay from sticking.
  • Vegetable oil – Lightly wiping a thin layer of vegetable oil on the cookie cutter will help prevent sticking.
  • Baby powder – The silky texture of baby powder makes it an effective release agent for polymer clay work.

When applying any of these agents, it’s important to create an even, thin layer and wipe away any excess. Too much cornstarch or oil can leave residues on the finished clay piece. Reapplying the release agent between uses will maintain its effectiveness.

In addition to basic household items, there are also specialty polymer clay release agents available for purchase. These are formulated not to leave residues or alter the clay color. Glycerin and PAM cooking spray are other options for release agents (according to Using release agents).

Cleaning and Storing Cookie Cutters

Cleaning your cookie cutters properly after each use is important to prevent baked-on residue and maintain their shape. Here are some best practices:

Rinse cutters immediately after use in hot water to remove any raw dough. Use a soft brush or cloth to gently scrub away stubborn bits.

For a deeper clean, fill a bowl with hot, soapy water. Let the cutters soak for 5-10 minutes, then scrub with a soft brush. Avoid abrasive scrubbers that could scratch the cutters.

For stuck-on residue, bring a pot of water to a boil. Drop in the cutters and let boil for 30 seconds. This should loosen any baked-on material. Finish cleaning with a soft brush.

Disinfect cutters occasionally by boiling for 1-2 minutes or running through the dishwasher. This prevents cross-contamination.

Make sure cutters are completely dry before storing to prevent rusting. Store in a dry, room temperature spot out of direct sunlight. Hang cutters from a rack or pegboard, or store in an organizer. Avoid tossing loose in a drawer.

With proper care after each use and storage, your cookie cutters will stay clean, intact, and ready to create festive cookies for many holidays to come!

Baking Tips

Proper baking is crucial for preventing polymer clay from sticking to cookie cutters. According to the Reddit post “Do I need some sort of silicon non-stick mat to work on?” https://www.reddit.com/r/polymerclay/comments/117gz36/do_i_need_some_sort_of_silicon_nonstick_mat_to/, baking at the right temperature and for the recommended time for the specific clay brand will help ensure the clay does not stick. Most polymer clays should be baked between 265-275°F for 15-30 minutes per 1/4 inch of thickness.

It’s important not to underbake the clay, as polymer clay that is still soft and pliable after baking will be more likely to stick to surfaces. Overbaking can also cause sticking by making the clay too brittle. Refer to the clay packaging for specific temperature and timing recommendations.

Baking on a layer of parchment paper can help prevent sticking to oven surfaces. Avoid glass, metal, and silicone mats which may interact with the clay. Place items 1-2 inches apart on the baking sheet so they have room to release any gases as they cure.

Troubleshooting Sticking

Even with proper preparation, polymer clay can sometimes still stick to cookie cutters. Here are some tips to try if the clay continues to stick:

Chill the clay – Place the clay in the refrigerator for 15-30 minutes before cutting. The colder temperature helps prevent sticking. Be careful not to chill too long or the clay can become brittle.

Flex the cutter – After cutting, gently bend and twist the cutter to help release the clay. Don’t flex too far or you can damage the cutter.

Tap out the clay – Gently tap the backside of the cutter on a hard surface to help dislodge stuck clay.

Wipe cutters clean – Use a soft cloth to wipe residual clay off cutters after each use. Built up clay residue can lead to more sticking.

Avoid overfilling – When cutting, don’t pack the cutter completely full. Leave a bit of extra space for the clay to release easier.

Try a release spray – A light mist of cooking spray or silicone spray can help prevent sticking.

Use a sanding pad – Gently rubbing the cut edges on a piece of fine grit sandpaper or sanding pad can help smooth and deburr.

As a last resort, slip a thin blade between the clay and cutter to gently pry and separate the pieces. Take care not to damage the cutter.

Alternative Techniques

While cookie cutters are a popular tool for creating shapes and cut-outs with polymer clay, they are not the only option. Here are some alternative techniques to try if you want to avoid issues with polymer clay sticking to cookie cutters:

Hand sculpting allows you to form the clay freehand into whatever shape you desire. It takes practice to sculpt smoothly and cleanly, but gives you the most flexibility and control over the final form. You can use your fingers, clay sculpting tools like loop tools or silicone tipped shapers, or improvised tools like toothpicks or popsicle sticks. The Blue Bottle Tree has an excellent guide to Free Polymer Clay Tools from Around the House that you likely already have on hand.

Molds provide shaped cavities that you can press or roll polymer clay into to achieve detailed forms. Molds are available in many materials like silicone, resin, or plaster and can be purchased or homemade. After shaping in the mold, you unmold the clay form to detail and bake it. Molds allow consistently replicating the same shapes.

Clay extruders push clay through dies to create long strands or tubes in different shapes like circles, squares, or star cutouts. You can then cut these extruded forms to length. Extruders require some equipment, but create consistent and uniform shapes and cutouts.

So explore beyond cookie cutters, and don’t be afraid to use your hands or household items to shape polymer clay creatively!

Advanced Methods

For more complex projects where basic application of cornstarch or water is not sufficient, there are some more advanced techniques to prevent polymer clay from sticking to cookie cutters:

Commercial Release Agents: Specialty polymer clay release agents like Magic-Glos[1] can be brushed or sprayed onto the cookie cutter. They create an invisible barrier to prevent sticking. Follow manufacturer instructions for best results.

Liquid Clay: Coating the cutter with a thin layer of translucent liquid polymer clay called Liquid Sculpey can act as a release agent[2]. Allow it to cure before using the coated cutter.

Clay Conditioner: Applying a thin coat of clay conditioner containing beeswax or carnauba wax can help release polymer clay[3]. The wax prevents the clay from bonding.

Cyanoacrylate Glue: Non-gel cyanoacrylate glue applied to the cutter will keep clay from sticking. The cured glue peels right off afterwards along with the baked clay[1].

These advanced methods may take more effort but are very effective for complex shapes where basic techniques fail. With trial and error, an ideal solution can be found.
