Build the Skeleton Structure of your Sculptures

Armatures are vital to strong sculptures. Learn about different methods for building strong armatures. A strong armature can hold polymer clay in virtually any complicated or precarious position, even look like it's floating in air.

The Importance of Armatures 

The Armature is the Skeleton of your Sculpture

A weak or insufficient armature can ruin an otherwise beautiful sculpture. Take your time and get the foundation of your sculpture right so it will last for years.

Basic Armature Making Tools 

1: Wire cutters
2: Needle nose pliers
3: Dremel tool or drill
4: Hammer
5: First Aid Kit (I'm serious, wire is sharp you will cut yourself)

Armature Materials 

This is a rundown of common material used to make armatures for polymer clay sculptures.

1: Aluminum armature wire
2: Floral wire
3: Fabric covered floral wire
4: Aluminum foil
5: Floral or Masking Tape
6: Sculpey Ultra-Light
7: Brass or steel rods
8: Apoxie Sculpt or other two-part sculpting epoxy
9: Super glue and/or 2-part epoxy glue
10: Wooden bases (craft plaques work well or you could cut your own from lumber)

Shop Safety 

Safety First

Practice proper safety precautions when working with armature materials. Most importantly remember to wear safety glasses, especially when cutting wire or using power tools.

Armature Stands 

Build extra supports for your sculptures.

Armature stands are used to give an extra support for a sculpture while you are working on it. They are relatively easy to build and there are many different designs depending on what your needs are.

Since the burning point of wood is much higher than the curing temperature of polymer clay you can put a sculpture in the oven while still mounted on the armature stand.

Typical materials and tools needed are:

1: Wooden plaque or cut piece of lumber.
2: Dowels or threaded steel rods
3: Dremel tool or drill
4: Various bits of hardware, wing nuts, bolts, screws, etc.

Have you been wanting a sculpting stand but don't want to spend a hundred dollars and you're not a carpenter? This is easy enough for anyone to make. You may already have many of the materials in your home. Mine took about an hour to make and only cost about twenty dollars for materials.

Noadi's Armature Jig 

I built this wire bending jig for making armatures a while back. It's made from a 8"x24" (20x61cm) piece of pine and lots of 1/8" (3.18mm) screws.

To make it I traced the male and female figure onto the board with a black marker in 1/6, 1/8, and 1/12 scale (these are the scales I use most often). Then I drew in the shape of the armatures adding screws to all the major joints where I wanted bends in the wire.

With this jig I can very quickly make consistently sized armatures.

Armature Jig



To Make Your Own
Supplies
8"x18" Board (this is an approximate measurement, it can be a little smaller or bigger)
Drill with 1/8" bit
1/8" screws
Screwdriver
Permanent marker
Armature diagrams printed at 1/6, 1/8, and 1/12 scale
Sandpaper (optional)
Clear varnish (optional)

Instructions
1: Sand and varnish the board if desired. It will help keep the marker from bleeding into the wood and the jig will last longer.
2: Trace the armature diagrams onto the board.
3: Drill holes at all the major joints where the diagram shows the wire bending.
4: Insert screw into all the holes.
5: Make armatures!

Resources for Figure Artists
This lens has the best reference sources for figure artists as I've found so far, from poses to anatomy to hands and feet. I've compiled it for anyone who loves to create artwork portraying the human figure, whether you draw, sculpt, or paint I hope there's something here to help you out.
Resources for Animal Artists
Unlike with humans it can sometimes be impossible to work from life with many animals especially exotic wildlife so reference photos are a must. Also as with all art based on life a good grasp of the anatomy is important. I've compiled a constantly growing list of websites and books to help you out.

Wire Armatures 

Wire armatures are the simplest type of armature for a figure sculpture. Aluminum wire is twisted into the basic shape of a human, animal, or creature skeleton and attached to either an armature stand or a wooden base.

Or dance, do gymnastics, etc.

This technique for making a sculpture appear to be balanced or floating is a variation on the wire armatures. I've used it several times now, for my big sculpture "Odin's Runesong", for my in progress "Selkie Emerging" and "Fire Dancer" sculptures.

Why Bulk Up an Armature?

Bulking up armatures with aluminum foil or other materials helps reduce the amount of clay needed. It also helps reduce the chance of not curing thick clay all the way through.

Bulking Up a Wire Armature with Foil 

Polymer clay more than 1/2 thick is difficult to cure properly, either the outside get over-baked and darkens or the inside doesn't cure completely and the sculpt can break down over time from the effects of still liquid polymer inside. For this reason and to reduce the amount of clay needed most polymer clay sculptors bulk up their armatures in the torso and head areas.

The simplest way to do this is just to wrap crumpled aluminum foil around the armature and secure it with tape, glue, or floral wire.

Foil Cores 

Foil cores are tightly compressed balls of aluminum foil used as an armature. This techniques works best for sculptures with round or egg shaped bodies such as heads and animals like rabbits, mice, or my favorite: cuttlefish!

Making foil cores is fairly simple. Crumple aluminum foil up into the general shape you want then pack it in as tightly as possible, I use a hammer to get it really tight. To help the clay adhere better either wrap the core in floral or masking tape or cover it in PVA glue (that's white glue like elmer's or tacky glue) and allow it to dry before adding clay.

Polymer Clay Garden Wall Face Plaque
The Troll Polyzine May 2001
Sculpting a troll face is not that difficult, mainly because the proportions don't have to be as accurate as when sculpting a human being. You can make funny faces and big noses, and they still look like that's what they were meant to be. The lesson is a good choice for beginners in 'humanized' claying. I hope you will give it a try.
Elvenwork Tips and Techniques
Over the years, Katherine has accumulated a wide array of techniques, some from constant experimentation with the medium, and some from interaction with the community of polymer clay artists. She devotes much of her time developing hands on classes for many of the country's polymer clay guilds, sharing the sculpting techniques she uses; however, that method doesn't reach the numbers of aspiring sculptors she would like to. This page is dedicated to them.

Other Techniques 

Other materials can also be used in armatures.

Epoxy: 2-Part sculpting epoxies such as Apoxie Sculpt and MagicSculpt set rock hard and can make for extremely sturdy armatures when used for bulking and securing wires together. The downside to epoxies are that they set quite quickly so you have a limited working time and is much heavier than alternatives such as foil, paperclay, or sculpey ultralight.

Paperclay: Used much the same as foil for bulking up an armature. Make sure to allow the paperclay to dry fully and apply PVA glue to it before adding polymer clay.

Sculpey Ultralight: A very lightweight porous polymer clay, sculpey ultralight makes for strong lightweight armatures when used for bulking or as a core. You must bake the ultralight armature before adding normal polymer clay.

Wire Mesh: Used as a support for thin structures such as fabric or fins. Wire Mesh is very flexible and easily shaped.

Removable Armature: Sometimes you want a hollow structure and a removable armature is the best way to achieve this. Good removable armatures are disolvable clays like cold porcelain or cornstarch based packing peanuts.

polymer clays - sculpey ultralight
Sculpey UltraLightT is the newest and most versatile member of the Polyform family of clays. UltraLight is lightweight and extremely soft but bakes so hard that it won't crack or break, even in larger pieces. However, UltraLight remains flexible when rolled thin, so it is ideal for paper crafts, especially for personalized embellishments or to duplicate add-ons at a fraction of the cost.
