Hand Soapdishes


These hand soap dishes are a two part project that will teach students the concept of positive and negative space.  You'll want to cover your tables with newspaper to make clean up easier.  To make the hands, each student needs to hold a small amount of plaster in their hand until it hardens.  I recommend doing only one hand since they have to sit still for 10 min while it hardens.  

Once students are ready, mix up a small batch of plaster and put it into palm of the students hands, make sure to cover the entire top surface but DO NOT get plaster underneath the hand or their hand will be trapped in the hardened plaster!  Once their hand is full, have them hold still until the plaster hardens (about 10 min).  The stiller they can be holding the plaster, the less chances of major cracking or breakage off the mold.  While the plaster starts to harden I explain to students how this will be the negative space of their hands and that we will use it like a stamp to create the positive space of their hand in clay.  You can show examples of positive and negative space in art too.

HINT: You may need to mix up multiple batches depending on the size of your class, try not to mix up to much at one time or it will harden before you get to pour it into their hand.  If you have never worked with plaster before, I recommend trying it out on your own before attempting with a class--it's a very manageable classroom material if you know what to expect!  

Once the plaster is hard, have students remove their hand slowly, small pieces will break off of the edges.  Write their name on the plaster and put aside to dry completely (12- 24 hours).  All of the crumbles of plaster should be wrapped up in the newspaper that you used to cover the tables and thrown away.  Make sure students wash their hands in a bucket not at the sink --plaster will clog up your sink!

For step two, you'll use the students plaster hand molds as a stamp and press clay into the mold.  I have students flatten out a piece of clay about the size of a large hamburger and lay that over the plaster mold.  Press the clay gently but firmly into every contour of the mold and then gently peel the clay away.  You should have a perfect positive of the mold with every detail showing.  You can use tools to trim and clean up the edges, make sure that you write each students name on the bottom of the clay hand (they will all look alike!)  Let them dry, bisque fire, glaze with a translucent glaze and glaze fire.  These hands make great soap holders or business card holders and make great Mother's and Father's Day gifts too!

Terracotta Warriors

This project is a great way to tie art and history together, if you are studying China or Asian cultures in your classroom, you can create an army of terracotta warriors with your class.  The Terracotta Army is a collection of terracotta (a type of clay) sculptures depicting the armies of the first Emperor of China. The purpose of these warriors was to protect the emperor in his afterlife and to make sure that he had people to rule over.  There are over 8000  life-size warriors, horses and chariots that make up the collection.  It had been buried until  farmers accidentally found them in 1974 while digging a well in a remote area of the Shaanxi Province.  


Once you have discussed the amazing magnitude of the terracotta army with your students and shown lots of pictures, each student can easily create their own warrior. You can use terracotta clay for this project if you want (it contains a lot of iron and hence it stains everything easily!) but I used a low fire white earthenware clay and stained the surface of the clay afterward to get the rich red tones.  Start by giving your students a piece of clay that is about the size and shape of a hot dog bun.  With a knife, cut the bottom third of the clay down the middle.  This will create two separate legs.  Then cut from where the armpit would be on an angle towards the outer edge of the block of clay to create each arm.  Next squeeze the clay to create a neck and round out the head with your hands.  This should give students a basic human form.  They can change the position of their warrior if they want to by bending the limbs to make it kneeling or sitting.  Next have them use tools and their fingers to create the details and features. Remember that if they add any clay on, they'll need to scratch-to-attach.  Use lots of references to look at the details in the uniforms of the warriors.  Once they are dry, you can bisque fire them and then I painted mine with a red iron oxide wash to give them their terracotta color. If you've used terracotta clay, you won't need to color them.  To make the wash use 2 parts red iron oxide to one part gerstley borate (all available at ceramic supply stores) and mix with water to a thin consistency.  Paint on the wash and then use a damp sponge to wipe the surface off lightly.  Glaze fire the pieces and you can assemble your terracotta army ready for battle!

Henna Hands

Henna is a natural dye that is used to decorate the body especially the hands for special occasions such as weddings in many Asian cultures. The designs are intricate patterns of shapes, flowers, spirals, waves and lines.  For this project, I show my students lots of examples or patterns and designs, we also practice a few on paper first.

You may want to cover your tables with newspaper to make clean up easier.  To make the hands, each student needs a latex glove (be sure to use thick gloves NOT the thin food service type), then mix up a small batch of plaster and pour it into the glove while the student holds it open. Once their glove it full, have them pinch it closed and hold it up until the plaster hardens (about 10 min).  The stiller they can be holding the plaster, the less chances of fingers breaking off once its dry, I have my students tell jokes or riddles while they wait.   HINT: You may need to mix up multiple batches depending on the size of your class, try not to mix up to much at one time or it will harden before you get to pour it into the glove.  If you have never worked with plaster before, I recommend trying it out on your own before attempting with a class--it's a very manageable classroom material if you know what to expect!

When the plaster hardens you can lay the gloves down on the table and carefully cut the glove off with scissors.  You should have a perfect hand shape which may stand up if the bottom is flat enough ( you can sand it flat if its not!).  I let these dry completely over night.  To clean up any plaster disasters, let it harden and then break it up with a scraper and hammer, through the hardened chunks away.  If you want to get it out of the bucket you mixed it in, let it harden and then flex the plastic bucket to pop it off the sides.  DO NOT LET PLASTER GO DOWN THE SINK!!  I set up a 5 gallon bucket of water for students to wash their hands and any tools in, then just dump that water outside.

Once the plaster is set, use watercolor paints to paint the entire surface of the hands, the plaster will absorb the paint quickly.  You can use this as a time to tie in a color theory lesson explaining the differences between warm colors and cool colors or just give them primary colors and have them experiment mixing.  Once the paint is dry, give students a selection of fine and ultra-fine sharpie markers to start their henna patterns with.  I encourage students to do at least 10 different patterns and to cover the whole surface.  They can use the patterns they drew earlier as references on their final pieces.

HINT: If you have broken fingers, they can be fixed!  Take a small drill bit and drill about 1/2" into the finger that is broken and also into where it connects.  Cut an inch long (or shorter) dowel of wood, such as a shish kabob skewer, dip the ends into glue and fit it into the drilled holes.  You can also add a little bit of glue to the plaster surfaces, push the broken pieces together gently and let dry!

Baby Bugs

These cute little bugs are easy to build and your students can make a bunch in a short period of time.  Start with a small sphere of clay, about the size of a large marble and elongate it into an oval for the body.  Roll out a coil of clay and flatten it gently with your hands, scratch to attach it onto the body to create the wings.  You can add on big bulgy eyes or a stinger tail at this point too.  Next I used nichrome wire (this is high temperature wire--do not use any other type of wire in the kiln!) and cut short lengths of it to create the legs, push the pieces into the clay and let dry, you could also add antennae this way.  HINT: You may need to let the baby bugs dry on their backs until they are strong enough to stand on their wire legs.  You can also make a small wire loop to push into the back of the bugs, so that you could hang them and create a mobile of flying bugs after they are finished.  If you want to tie this project into your classroom curriculum, have students make each section of their insects anatomy realistic (head, thorax, abdomen, legs, wings & antennae).  HINT: If they are standing on their wire legs in the kiln for glaze firing, you can glaze the entire surface of the bugs without risking them sticking to the kiln shelf!
