ABOUT THE MOLDS
Molds you receive are made of polymer clay.
Polymer clay is basically a low temperature clay containing plastic which hardens when cured at low temperatures (275 degrees)
The mold is hard and will not bend (is not flexible)
Although polymer clay molds are deemed not food safe they do work well for fondant, gum paste. Care should be taken for proper cleaning to avoid bacteria. A soak in rubbing alcohol and water rinse, air dry is highly recommended if you decide to chance it. Food grade silicone (bendable,flexible) molds are available. Request a food grade mold if it is not listed.Prices are higher for silicone molds.
Some molds are not available as food grade.
Size given is the item that is removed from the mold.
Size is usually noted several times in a listing. Please notice the size before ordering to avoid possible disappointment.
Before baking, adjustments can be made to the item you have molded.Manipulating the unbaked clay will make your creation unique.
Example: change the expression on a face to personalize your work.
How to use a hard push mold
- Prepare the mold by treating it with a release agent. Water and talcum powder are popular choices. Be generous with your release agent, but remember that using too much will clog the mold and prevent the finest details from transferring completely. Excess powder should be tapped off.
- Form your well-conditioned clay into a ball or a sheet. (For deeper molds, a ball works best. For shallow molds, a sheet will suffice. Experiment to see what yields the best results with your particular mold.)
- Place the ball of clay into the center of the mold. Press the clay firmly and evenly until the mold is filled. Depending on how much clay you use, some clay may overflow around the sides of the mold. (This overflow may or may not be a problem. If excessive overflow gives you trouble with removing the casting, try again with smaller and smaller amounts of clay until you learn exactly how much to use.) Avoid rocking the clay back and forth, as this can cause the clay to move in the mold. The result is often distortion or double-impression of part of the pattern.
- Remove the clay from the mold. You may be able to simply lift the clay out. However, if you find that you have difficulty removing the clay without distorting it, try these methods:
- Attach a plug of scrap clay to the back of the clay in the mold. Use this as a handle to pull the clay out.
- Allow the clay to cool before trying to remove it. You can even put it into the fridge or freezer to make it firmer.
- Start with refrigerator-chilled clay. This is especially helpful if you are starting with soft clay.
- Placing the mold in the freezer before use works well.
- If there is excess clay (overflow), carefully trim it away with a craft knife. Now is also the time to do any tweaking to the shape, before you cure it (according to manufacturer's guidelines).
- Work on a ceramic tile. It can be placed in the oven along with the piece.
- It's good to cultivate a habit of cleaning your molds with isopropyl alcohol after each use. This will make them last longer, and it will also make the next use easier-- no sticky residue to contend with.

Polymer Clay for Beginners
By Joe Kempf
Polymer clay is an exciting and fun hobby to get into. It is one of the few hobbies one can see their projects take off and take shape in a short period of time, and artists find this hobby to be very fulfilling!
This tutorial is very basic for beginning your polymer clay experience. Polymer clay is a fun hobby for all ages. It is one hobby that is especially helpful in developing dexterity and eye-hand coordination for patients needing this type of therapy. Items can be made from polymer clay that are as simple as a fun figurine, or as complex as a large and complicated sculpture or exquisite piece of jewelry. We will not go into the how to do these different projects in this tutorial, but rather, we will focus on what a person needs in order to begin in this fun and exciting hobby!
Polymer Clay is an oven bake modeling clay composed of polymers, resins, coloring agents and fillers. It is a synthetic (man-made) clay, made from a plastic, polyvinyl chloride (PVC - the same stuff your water pipes are made from) base. The moisture in the clay keeps it continually soft until it is baked, removing the moisture, while retaining its color and size. It is available in many colors, including metallics, glow-in-the-dark, various types of stone, as well as other textures and colors. It can be used to simulate stone, gems and semi-precious stones, porcelain, wood, glass, and even cloth.
Polymer clay comes in many different brands and sizes; all with varying prices. On the most part, polymer clay is a very inexpensive hobby, except in some countries outside of the United States. Even in those countries where clay is more expensive than in the U.S., clay can be purchased and shipped at more reasonable prices, depending on the shipping costs involved.
Things that can be done with Polymer Clay
Polymer clay can be used in many different types of crafts. It is used to make jewelry, decorations, pottery, sculptures, and anything else the imagination can create. Many different crafts have been used to develop the techniques used in polymer clay; such as cake-making, ceramics, metal-working, etc. Clay is also used to cover many different objects, such as wood, fixtures, pens, and glass wares. Polymer clay can be mixed much like paint to create your own variations of color, and can be colored with powders, chalk, ink, glitter, colored pencils, powdered makeup and paint, to name a few. Only your imagination limits what you can do with polymer clay!
Precautions in using Polymer Clay
Polymer clay can be baked in your home oven, an air-circulating convection oven, or even a toaster oven. Most artists like to use a toaster oven to prevent food contamination by lingering fumes attaching to the heating elements and other parts of the oven. Regardless of which type of baking is used, proper ventilating is very important. When using cookie sheets, or other items to place your clay on, it should be lined with foil or cardstock during baking. If you use kitchen utensils or toys in the preparation or modeling of the clay, be careful to keep it separate from your other wares so it will not be used for food preparation or by playing children. Always wash your hands with soap and warm water after working with polymer clay. Adults should ALWAYS SUPERVISE CHILDREN when working with polymer clay. The clay can be baked within baking bags to prevent the release of fumes, if you wish to keep your oven from being contaminated with the chemicals present in the clay. The inside of the oven can also be cleaned with baking soda and water to remove contaminates.
Storing Polymer Clay
Polymer clay should be stored in its original wrapper until it is opened. After opening, the clay can be stored in any air-tight container or plastic “zip-lock” type bag. It is best to wrap in wax paper before placing in the container to prevent “sticking.“ If stored in food containers, be careful not to reuse the container for food storage. Long-term storage can be accomplished by placing in the refrigerator or freezer; assuring it is dry and away from light.
Conditioning is the preparation of the clay for use by warming it, either by kneading and stretching, or by any other method (such as wrapping in a heating pad) in order to increase the clay's pliability and ease of use. Different brands of clay can be conditioned easily and in a very short period of time by kneading and stretching. Other brands require the use of pasta machines, blenders, and other items to assist in the conditioning of the clay. A pasta machine (with or without a motor) is the most common method used in conditioning clay. Simply cut the clay into chunks, flatten it thin enough to feed into the pasta machine, and then feed it through while turning the handle of the machine. The clay will usually require several passes through the pasta machine in order to condition it properly. It is best to do this BEFORE blending or mixing colors, and then the clay can be blended and mixed after it has reached a usable softness. The softer clays can become TOO SOFT to work with and may require refrigeration in order to make it easier to model without loosing its intended shape.
Baking Polymer Clay
Each brand of polymer clay has its own ideal baking temperatures and baking times, usually printed on the original packaging. ALWAYS follow the directions on the clay package. Be sure to preheat your oven to the desired temperature before placing in the oven. Bake the clay on foil, index cards or a ceramic tile to keep it from loosing its shape and/or sticking to the appliance. Allow the clay to cool completely before handling after baking.
Painting Polymer Clay
Water-based acrylics are the ideal paints to use on baked clay. Other types of paints can be used, although some will require coating with a sealer after application. There are many paints, glazes, inks, and pigment powders designed especially for polymer clay; each with its own “manufacturer’s recommended” instructions.
What You Need to Begin
Marble, glass, or a ceramic tile are great work surfaces, as they are cool and can be easily transferred to the oven with minimal disruption to the worked clay. Cardstock, index cards, wax paper, or parchment paper can also be used for the same purpose. Other useful tools such as a rolling pin, polymer clay cutting blades, and shaping tools are very useful in working with polymer clay. These can be made from tools and items you may have around the house or in your workshop. Study some of the manufactured polymer clay tools, and then look around to see what you have that can be developed for your purposes. A skewer or large pin can be used for piercing to make holes in your clay beads. If you wish to invest in some of the more specific polymer clay tools, you will want to purchase a pasta machine (certain brands may come with a motor, but these are very expensive); measuring tools to assist in making beads, eyes, etc. are also available. You will also want to invest in cutting blades, which are made for slicing clay into very thin layers, carving and sculpting tools, shape cutters, push molds, and a clay extruder (a device used to squeeze clay through a tube through a plate with different shapes cut into it, and produces long strips of differently shaped clay). You can also purchase sheets that will pass through the pasta machine with the clay in order to make different impressions on the clay.
Now, all you need is your imagination, some polymer clay, your work surface and tools, and GET STARTED. You can only develop your skills by diving in. If you don’t like how your project is developing, simply “smash” it up, and begin again! You will quickly see your masterpieces improve with each new project, and as you network with your new polymer clay friends. Whichever direction you take with your polymer clay hobby, most of all, we hope you will have lots of fun!
All clays need rolling & squeezing (kneading) to become soft & pliable.
Rolling between palms, twisting, & running through a pasta machine
are easy ways to condition clay.
If you do not use a dedicated pasta machine (only for clay) use an acrylic brayer,
a piece of PVC pipe, or a heavy glass bottle to flatten the softened clay into sheets.
NOTE: Sculpey SuperFlex may need to be pre-warmed (under a low-
wattage light bulb, or by holding for 5 - 10 minutes in warm hands)
before conditioning. But, SuperFlex is very heat reactive.
If your hands are hot and it gets a bit sticky, set aside & work on
another color or piece of clay until the original piece cools.
How To Use A Push Mold
Practice to determine how much clay will fill your selection. It takes less than you think.
When building in color layers, a little goes along way. Use a clay shaper, paintbrush
handle or a pencil eraser to pull any excess away from the lower boundaries.
You want to just fill the lower boundaries, even leaving them a little shallow.
The final layer of color will fill into the shallow areas, leaving a neat border.
But, if the first colors are "domed" up, the final molding pressures will force the
"dome" out of its boundaries, leading to a smeared look. Less is more in this case.
When the lower boundaries are filled with their colors, press the main clay color
into the center of the mold. Gently press & pat so it flows into shape. When the clay
is nearly level with the top of the mold, use your index finger to gently pull any
excess away so that you can see all edge boundaries of the mold.
This eliminates a "skin" that would need to be trimmed away.
For an easy release, put the mold into the freezer for 90 seconds or longer.
Remove from the freezer, and gently "pop" your molded piece out by
pressing the backside of the mold. It will come out like an ice cube.
Bake molded items on index card placed on baking surface.
DO NOT place pushmolds in oven at any time.
If any color residue remains, wipe the mold out with a baby wipe or a
window cleaner dampened paper towel.
Use an oven thermometer to check the temperature of your oven or toaster oven.
Place your creations on baking parchment, copy paper or index cards,
and then place in a glass dish. Place the dish in the middle of the oven,
away from heating elements.
CAUTION: Contains pigments that may stain. May damage finished
Do not place unbaked clay on furniture, flooring, carpeting, unholstery or fabric.
Do not back clay at temperature hotter than recommended to speed up process.
Do not microwave.

How to use a mold with PMC
Knead a piece of metal clay and form into a rough log that is about the same size as the item to be molded. Smear a light coating of vegetable oil onto the clay surface and press the clay into the mold. Work firmly with your finger, pushing the clay into all the crevices and completely filling the mold cavity.
Trim away some of the excess clay if it is too high above the mold surface, but leave a thin tag of it to provide a handle to pull the clay out of the mold. Use the tag to ease the clay gently out of the mold.
Lay the piece face up on a tile. Use a knife to trim away the excess clay all around the item and save it to use for another project.
Dry the piece and then use files and sandpaper to refine the shape further.
When cool, brush,burnish and polish.File away any sharp edges.
