The slab building technique involves rolling out clay to an even thickness - usually 1 cm - then cutting shapes, folding, bending, manipulating and joining together to form a finished object.
Slab objects are left to dry EVENLY before bisque firing for at least 7 days - turning regularly
Start with wedging and throwing clay on a flat surface (covered with canvas).
Spread the clay out by patting it with your whole hand.
Flip the clay over carefully.
Create paper stencils for the box's sides.
Trace/cut with a needle tool.
Place the 4 sides aside. Let the clay firm up to become leather dry. (For most clays it would take about an hour).
You can roll a slab for the bottom of the box now.
Place the 4 sides over the "bottom" slab.
Make sure the sides are straight.
Use needle tool to cut away the extra clay.
Add a coil in the corners to make seams stronger.
Gently press the coil into the corner.
Use the same steps to cut out 4 feet for the box.
Score and slip.
Smooth all sides inside the box. Use a wet brush if you cannot reach it with your hand.
Now it is ready for decorating.
