What is polymer clay?
Return
Polymer
clay is a manufactured "clay" that was originally developed
in Germany in 1930. The "clay" is made from polyvinyl
chloride, or PVC. Some of you may recognize this as
the plumbing in your homes. PVC is mixed with a
plasticizer and colors are created by simply adding a color
pigment. Polymer "clay" can be found in a wide variety
of colors including translucent, granite textures and
neon-day-glow
colors.
After forming the "clay"
you can bake it in any standard home oven at a low
temperature, usually around 275º F, although this may vary
by brand. The length of baking time depends on the
thickness and/or shape of the design created.
When baked, polymer "clay" does not shrink or fade in color.
After the curing process,
you can do many things with the creation, including
drilling, sanding, painting and polishing.
Properly
stored, unbaked polymer clay has a very long shelf-life of
upwards to two years. The shelf-life can be prolonged by
storing in the refrigerator or freezer.

Where can I get polymer clay?
Return
Just
about any craft store, like Michaels, will carry a selection
of polymer clay and accessories. Occasionally you may
be able to find
polymer clay at discount stores like
Wal-Mart. The internet is also a great source for
polymer clay accessories, although, if you read the
About Us page on this site, you'll
know that finding all the clay accessories you need can be
difficult to say the least. That's why I've dedicated
this site to making the lives of polymer clay artists a
little easier by creating a one-stop shopping spot for all
of their clay and accessory needs. So while your here,
please check out our large selection of
products and please feel free
to let me know if there's anything you can't find here or
elsewhere.

What can I do with polymer clay?
Return
Polymer
clay has an almost infinite number of uses. It's great
for creating pendants, lamp shades and other home decor, beads, jewelry, pens, faux stones,
jewelry and trinket boxes, vases, candle holders,
sculptures, pictures and picture frames, figurines, dolls,
miniature furniture, and my favorite, miniature villages.
It's also great for using with other materials like
embossing powders, glitter, metal, and any other product
that can tolerate temperatures up to 275º F. There are
several websites dedicated to the use of polymer clay.
We also carry a broad selection of books here.
Polymer clay
should NOT be used for any product that will come into
contact with food, or small children. (Small children
like to put things in their mouths.) Cured objects can
be sanded, drilled, buffed, painted, glazed, etc. The
possibilities are limitless...just use your imagination!
-
What tools do I need?
Return
First
and foremost, you must have access to an oven. You can
use your kitchen oven, or a toaster oven. Kitchen
ovens are great for the occasional crafter, although if you
bake clay frequently, I'd suggest getting a toaster oven.
This makes it much easier to work on your crafts in a more
convenient area, or away from high traffic areas of your
home.
Second, I
must say, for the sake of being completely honest, that it's
quite possible to create things with polymer clay using no
tools at all, other than an oven. While
tools do make
most projects a lot easier, and quicker, many things can be
created simply using your hands. I, personally, am a
tool junky. If they make it, I want it, but my
suggestion is to work in the manner that suits you best.
However,
since this question is about tools, I will run down a list
of the most common tools used with polymer clay:
-
As
I mentioned above, you absolutely must have access to an
oven. Based on how often you work with polymer clay
you may want to stick with your kitchen oven (never bake
clay on pans you use for food preparation), or you may find
that you'd be better off purchasing an inexpensive toaster oven dedicated solely to polymer clay baking.
-
My number
one, can't live without tool...the
pasta machine. I
injured my hand a couple years ago, which required surgery,
so the
pasta machine has become irreplaceable to me.
It's great for conditioning the clay, which saves my hand
from a lot of stress and pain. On top of replacing
your hands for conditioning, it's perfect for creating thin
sheets with an even thickness. Most come with either
seven or nine thickness settings. Also, make sure you
get one that can be mounted to your table or desk, otherwise
you'll be struggling the entire time you use it.
-
While
we're on the topic of tools used for conditioning, I'll go
ahead and cover the food processor. These seem to be
gaining popularity among polymer clay artists, although I
have to admit, it's not one of my favorites. You can
find these fairly cheap at Wal-Mart or K-Mart, and we also
carry them here. Just make sure you dedicate your food
processor to polymer clay. Do NOT use the same
food
processor for food. When using a food processor you
should add a couple drops of mineral oil to make the
pasta machine
work smoothly. Otherwise, you risk burning up the
motor.
-
Brayers
or acrylic rollers are another
tool similar to the
pasta machine.
Although they aren't good for conditioning the clay, they're
great for flattening the clay if you don't have a
pasta machine
or desire a thicker sheet of clay than what the
pasta machine produces. These are also great for
reducing square canes...just make sure you work your way out
from the middle of the cane to minimize picture distortion.
-
Next in
line of importance is a work surface. The easiest and
cheapest way to find a glass work surface is to purchase a
$9.00 cutting board at Wal-Mart, although we do carry them
here as well. Just make sure when purchasing that the
back side is smooth (the "top" is usually rough textured).
If you have a glass table you don't mind using as a work
surface, those work great as well. Also, I've heard of
some people using tiles as work surfaces. These are
great because you can work on the tile and then simply put
the entire piece into the
oven for baking. This
eliminates the stress put on your clay pieces by moving.
Just be careful when choosing tiles. I had a bad
experience with a tile that apparently had been treated or
coated with some sort of finishing material. When I
baked my piece on the tile it distorted the color of the
clay and my work was destroyed. Again, I would
recommend dedicating this piece solely to polymer clay work
and avoid using in food preparation.
-
If you
create canes, you really should have a
tissue blade.
They're longer and thinner, which is better for slicing
canes, than craft knives or x-acto knives. This
lessens distortion of the cane design. They're
also flexible which means you can cut with a curve. If
you need to slice flat sheets in straight lines the
tissue
blade is great for that as well.
-
A
clay
gun is another great
tool, especially if you make a lot of
figurines, dolls or ornaments. They make uniform
shapes that you can use to create hair for dolls, or even
trim a christmas-tree-shaped ornament, or whatever idea you
imagine. These can usually be found at Michael's and
we also have a couple types here. We also carry a few
clay gun accessories, which makes the extrusion process
easier, since the standard clay gun can be hard on your
hands. Just make sure your clay is well-conditioned
and very warm when you put it into the
clay gun. This
also reduces stress on the hands.
-
You'll
also need a pan for baking. You can use one dedicated
to polymer clay, or use disposable pans. My personal
preference are glass cake/casserole pans. If you're
baking flat pieces you should cover the pan with parchment
paper, or freezer paper (wax side up).
-
Piercing
tools are mandatory if you make a lot of beads. Some
people prefer the actual tool, although you can also use
toothpicks or quilting needles.
-
Another
great tool for those bead fanatics is the
bead
baking rack.
It's great for baking beads without creating spots from
baking them directly on the pan. A homemade version of
the bead
baking rack that I came up with (out of my
frustration in finding a
bead
baking rack) is a
disposable pie pan, my piercing tool and toothpicks. I used the
piercing tool to poke holes into the disposable pie pan.
I then placed toothpicks in the holes and placed my beads on
top of the toothpicks. This prevents the spots that
form during baking directly on the pan.
-
Rulers
are great for creating beads or pendants of equal size
and/or thickness. They can be used to make marks on
the clay which can serve as a guideline for slicing.
-
Templates
are another great
tool for creating consistently sized
beads.
-
X-Acto
Knives are great for trimming and cutting shapes.
-
Shape cutters and
cookie cutters are also great tools to have for
obvious reasons.
-
You may
also need paint brushes either for use in smoothing the
clay
or in painting the baked product.
-
Is polymer clay safe?
Return
Although
polymer clay is a non-toxic product, it is highly recommended that
you do not use any of the same tools for food preparation.
If you work on your clay in an area that may come into
contact with food, make sure you clean the area thoroughly
before using in preparing food. Working with polymer clay with leave a "film" on your hands and the
tools used,
which can be resistant to soaps. I usually rinse my
hands in alcohol and follow-up with soap and lotion to
prevent dry skin. Alcohol is also great for cleaning
your tools. I usually just wet a paper towel with
alcohol, but alcohol wipes and "Wet-Ones" also do the job.
Make sure you clean your hands thoroughly before eating or
touching food.
When
polymer clay is baked at the correct temperature, there is
no hazard. However, extended inhalation of the fumes
should be avoided. If polymer clay is burned, you
should immediately ventilate the area. When burned,
polymer clay produces gas that is irritating to your eyes
and lungs. It's recommended that you avoid the area
until all fumes are gone. Make sure you remove your
pets and small children from areas that contain fumes.
You should also thoroughly clean your oven before using
again.
-
What is the difference between different brands of clay?
Return
Polymer clay
usually bakes between 260ºF and 275ºF.
It varies by brand and type (glow-in-the-dark and fluorescent clays usually bake at a lower temperature).
Always be sure to read the label since the temperature can
vary between brand and type. Also, it's highly
recommended that you use an
oven thermometer, since most
ovens are off by 25-50ºF.
Thicker items bake longer than thinner items. Most
clay brands recommend 15 minutes for every 1/4". If
you're not sure how long to bake, just remember that longer
is always better. Polymer clay strengthens for up to
two hours, and since the clay is waterless, it can be baked
over 24 hours without damaging the clay, assuming the
temperature is correct. If the oven is too hot you
risk burning the clay or losing color. As far as
comparing other variances between brands, the best info I've
found so far is located at
Polymer Clay Central.
-
How is the clay prepared for use?
Return
There are
several ways to prepare the clay for use. The simplest
is to just begin working the clay with your hands.
However, I've heard of many different ways of warming the
clay. For example, some people carry a pack of
clay
around in their pocket to use body warmth to soften the
clay. Others may use the lowest setting on a heating
pad, or simply floating the clay (in a Ziploc bag) in warm
water. Then the use of the tools I mentioned above
come into play. Many people use the food processor to
warm the clay, which also conditions it (see
"How do I use a food processor to condition the
clay?"
for details). I personally prefer to warm the clay by
simply playing with it. After warming the clay it
needs to be kneaded for conditioning. Another option
is to run the clay through a pasta machine until
well-conditioned.
You
should always wash your hands before handling polymer clay,
especially when changing colors. Unless you use a food
processor, the clay should always be kneaded by hand until
fully conditioned. You'll know the clay is fully
conditioned when it stops crumbling. Kneading is a
simple process, you really just have to play with the clay.
It eventually warms up and you can roll it into a log, fold
and repeat, until the clay is completely pliable.
Alternatively, once the clay is soft enough to form logs,
you may choose to use a pasta machine to condition the
clay.
Just start with the thickest setting on the pasta machine.
Use your hands or a brayer or
acrylic roller to flatten the
log and then run through the pasta machine. Simply
fold the clay and run through the pasta machine again,
repeating until the clay becomes softer. About 10-15
passes should condition the clay for use. This also
keeps the clay from being unstable and brittle once it has
been cured. If the clay isn't conditioned properly
before use, the baked product may crack or have a porous
look to it. You can also use this process to combine
colors to create your own.
Sculpey Moldmaker and
MixQuick are
softening mediums developed by
Sculpey and FIMO, respectively, to make the clay easier to
work. Combining one part
softening medium to five
parts clay is a good guideline rule. You may also use
a bit of petroleum jelly. However,
Sculpey is a much softer
clay than FIMO, but it also requires proper conditioning.
-
How do I make beads?
Return
Beads
are one of my favorite things to make. The simplest
bead is made by taking a piece of conditioned clay and
lightly roll it between the palms of your hands until it
becomes a round ball. Alternatively, you can use a
bead roller, which enables you to make many differently
shaped beads. Once you have your bead formed, use a
piercing
tool to pierce the bead. Just barely push the
piercing
tool through to the other side, just enough to break the
surface. Then pierce the bead again from that side to
complete the hole.
Marbled
beads can be made by combining 2-3 complimentary colors.
You can blend them by hand or with a pasta machine.
Once you've reached the marbleized affect that pleases you,
form the clay into a bead and follow the instructions above
to pierce and bake the bead.
In
order to ensure that all your beads are equally sized, you
should use a
template. However, instead of using the
template, you can also roll out a snake of clay and then
using a ruler, measure out equal lengths of clay for each
bead.
To learn
about the best ways to bake your beads check out "What
kind of tools do I need?" For other types of
beads,
please check out our Tutorials section.
-
How can I adhere clay to glass?
Return
Some polymer clay
artists will bake the clay onto the glass piece, then remove
it and glue it. My personal preference is simply
coating the glass with Translucent Liquid Sculpey (TLS) and
then apply the cane slices or clay pieces on top of the
TLS.
This ensures that the entire surface of the clay comes into
contact
with the clay which gives it a better hold. However,
the only glass I apply clay to tends to be vases and candle
holders. If you're doing something like applying clay
to glass balls or glass eggs, for instance, you may want to
follow the baking and then gluing technique. My
suggestion is to use "Goop" or "Zap-A-Gap" after the
clay
and glass have both cooled completely.
-
How is the clay cured?

Polymer clay
usually bakes between 260ºF and 275ºF.
It varies by brand and type (glow-in-the-dark and
fluorescent clays usually bake at a lower temperature).

-
What kind of finishes are there?
Return
There
are many different ways to finish your baked polymer clay.
Check out our Tutorials to learn
how you can sand and buff baked polymer clay to get a nice
shine. You may also want to apply an
acrylic lacquer,
which you can find here. Sculpey and FIMO both offer
paintable acrylic lacquers in
glossy and
satin finishes.
We also carry a selection of acrylic spray lacquers.
I've also heard of some people using polymer floor wax to
create a shine on their polymer clay projects.
-
How should the clay be stored?
Return
Clay
should always be stored in containers made of materials that
will not interact with the plasticizers in the clay.
Glass or metal containers tend to work best, although they
also tend to be more expensive. I've used plastic
storage containers for storing my packaged clay. Any
clay that has been opened I first place into a sandwich bag.
As for caness, I first wrap them with wax paper, then place
them in a sandwich bag. This helps prevent distortion
of the cane. Make sure you always keep the storage
containers away from heat and direct sunlight. This
could essentially bake the clay over time. It's best
to keep the containers in a cool place, such as a basement,
or in the refrigerator or freezer.
-
What type of things can I make with polymer clay?
Return
Polymer clay has an almost infinite number of uses. It's great
for creating pendants, beads, earrings, necklaces, pins,
barrettes, bracelets, anklets, pens, faux stones,
jewelry and trinket boxes, vases, candle holders, light
plate switch covers, sculptures, pictures and picture frames, figurines, dolls,
miniature furniture, and my favorite, miniature villages.
You can also cover vases, glass balls, picture frames or
anything else that can withstand baking temperatures up to 275º
F. It's also great for using with other materials like
embossing powders, glitter, metal, and any other product
that can tolerate temperatures up to 275º F. Polymer clay
should NOT be used for any product that will come into
contact with food, or small children. (Small children
like to put things in their mouths.) You'll never find
yourself short of ideas, and there are plenty of
instructional
books to be found.
-
What are canes?
Return
Canes are
created by using multiple colors of clay to form designs
within the cane. The best way I can come up with to
explain a cane is by using a poker chip as an example.
Let's assume the poker chip has an identical design on both
sides. If you place ten poker chips together to create
a log this would be the "cane." The design on the
poker chip runs all the way through the cane. You can
slice it anywhere throughout the log, and see the same
design. The designs are created by making small logs
of clay at a time, and placing them together to create a
larger picture. Once your picture is complete, you
have a thick log, which you have to carefully press and
stretch. Doing this from the center out is usually the
way to get the least picture distortion.
It also helps to eliminate any air pockets that may be
trapped in the cane. Once the cane is fully compressed
you may reduce the picture side by lengthening it, also
working from the center out. Check out our
Tutorials section for
instructions on reducing canes.
-
Can adhesives be used with polymer clay?
Return
Since
polymer clay contains plasticizers it can be difficult to
glue. Polymer
clay sticks best to polymer clay, however, some
glues will
withstand for a period of time, but eventually all of them
will release their hold. The best glues to try are
"E4000," "Goop," or "Zap-A-Gap," although they will
eventually lose their grip as well.
The best
way to attach jewelry findings to clay is to bake them into
the clay. When doing this you should create a hook or
bend in the wire because straight wire will simply slip out
of the clay eventually. I also like to reinforce this
by using Translucent Liquid Sculpey, which can act as a
"glue" but when baked is actually a polymer clay.
-
What type of jewelry findings should I use?
Return
Any
jewelry findings that you use with any other beading or
jewelry making works well with polymer clay. You may
need various beading tools when creating jewelry, which can
all be found here.
-
What kind of molds can I use?
Return
Several
companies make molds especially for polymer clay, the more
popular two being AMACO and Sculpey. However, you can
make your own molds from any small item around your house.
I've made molds from figurines and dolls, but the
possibilities are almost limitless.
Sculpey Moldmaker
is an awesome product for creating your own molds.
After baking they remain flexible which makes them a lot
easier to work with than if you used regular clay to make
the mold. You should use cornstarch or
talcum powder
to prevent the clay or
Sculpey Moldmaker from sticking.
Simply brush the powder or cornstarch on the surface of the
item you want to mold, and I'd suggest brushing it on the
surface of the clay as well. Depending on what you're
creating a mold of you may be able to bake the object along
with the clay, or very carefully remove the clay from the
object and bake. You should always allow the mold to
cool completely before using it. Also, when using the
new mold, you should use the talcum powder or
cornstarch
again.
-
How can I use powders with polymer clay?
Return
There are several different
types of powders you can use with polymer clay, including
blush, eye-shadow, chalk, spices, and brand name
embossing
powders like PearlEx and Eberhard Faber Powders. They
can be used with polymer clay in a few different ways.
You can use powders with cured and uncured clay. You
may either mix the powder in with the clay for various
affects, or brush or sprinkle the powder onto the surface of
an object. Just be careful to not inhale any powder products, since they can be very dangerous. After the
clay has been cured you can attain different results by
sanding the object. You should always use an acrylic
lacquer or some other form of sealant to keep the
powder
affect from wearing off the finished product. Look for
Tutorials on using powders with
clay.
-
How do I use
a food processor to condition my clay?
Return
Food
processors are a great way to soften and condition polymer
clay. Just make sure that you use a food processor
that is dedicated solely to this use, and never used for
food preparation. To use the food processor, cut a 2
oz. block of clay into twelve squares Then pulse the
food processor until the clay quits clumping. Then run the
food processor for about thirty seconds. The clay will
then be warmed and will form small balls. You may need
to add a drop or two of mineral oil or Sculpey Dilutent
(plasticizer) if it feels dry. Be careful not to add
too much oil, as this can may the clay too soft and sticky.
Then press the balls of clay together and remove from the
food processor. You can then flatten the clay and run
it through a pasta machine.
-
My pasta machine is leaving
black streaks. What should I do?
Return
It's not
uncommon for pasta machines to leave black streaks on your
clay, however it does go away eventually. Streaking is
more common with some brands of clay, apparently due to a
chemical reaction with something in the clay. I've
also heard that it may be very tiny metal filings from the
scraper bars underneath the rollers. You can also
clean your pasta machine by running alcohol-soaked paper
towels through it several times. You should always do
this with a new pasta machine.
-
What is Translucent Liquid
Sculpey? Return
Translucent Liquid Sculpey (TLS) is a liquid form of clay that looks similar to Elmer's School Glue.
However, it has no adhesive quality while in it's liquid
form, although once baked it proves to form a very strong
bond between polymer clay objects. TLS is great for
creating a stained glass affect, reinforcing
jewelry
findings onto the jewelry pieces and for many cool affects
like photo/image transfers. You can also use
oil-based
paints or PearlEx powder to add pigment to
TLS, although the
more pigment you add, the weaker the bond gets. Check
out our Tutorials page for some
neat project ideas and uses for TLS.
