- Polyform gloss glaze for polymer clay
- Paintbrushes
- Unfinished wood ball knob
- Glue gun/glue gun sticks
- Measuring tape
- Wax paper
- Clean, smooth work surface (ceramic, glass, craft mat, or wax paper)
- Glass vase, cup, or votive with flat, straight sides to use as a mold for clay shape (optional)
- Cardboard or plastic file folder (to cut template)
- Acrylic rolling pin for polymer clay
- Polymer clay rolling machine (optional)
- Clay cutting blade or single edge razor blade
- X-Acto knife
- Clay piercing tool or toothpick
- Cookie cutters (optional)
- Oven
- Baking sheet
- Plastic bags or storage containers for clay storage
DIRECTIONS:
-
Review the instructions on the polymer clay package for baking temperature and timing. These instructions make one terrazzo jewelry holder.
- To begin, knead polymer clay to soften.
- Use a measuring tape to determine the circumference of your glass container and add 1" to that length. This extra length will help you cut and join the seam later.
- Decide how tall your jewelry holder will be (we made ours 3" tall).
- Using these dimensions, cut a rectangle template out of cardboard or a plastic file folder.
- Roll out a 1 1/4"-thick slab of white clay using an acrylic rolling pin or polymer clay machine.
- The slab needs to be larger than the template.
- Set aside.
- Sandwiched between two pieces of wax paper, roll out individual clay colors to thin pancakes.
- Next, cut small shapes for the terrazzo pattern using your cutting tool.
- Cookie cutters can be used to randomly punch overlapping shapes creating the terrazzo look from the intersecting forms.
- Arrange terrazzo shapes across the white slab.
- Colorful pieces should be small and spaced far apart because the slab will be rolled one more time, and they will "smoosh" slightly.
- After terrazzo shapes are placed, cover the slab with wax paper and gently roll to smooth the surface. Careful not to add too much pressure and distort the terrazzo shapes.
- Place the rectangular template on the clay slab and use it as a guide to cut the top, bottom and one side of the slab.
- Wrap the slab around your glass container to form the curve shape and trim off the excess.
- Gently rolling the slab will leave a mark in the clay, indicating where to cut off the excess slab.
- Remove the slab from the glass container, cut off the excess, crisscross the joining seam, and blend with your finger.
- Roll two circles of 1 1/4"-thick white clay large enough to be used as a lid and a base.
- Use the glass container to trace and cut the clay base with an X-Acto knife.
- Place the completed terrazzo slab on the circle base, crisscross the joining seams, and blend with your finger.
- Use the second white clay circle to make the lid. The now completed terrazzo jewelry container will be the template. Trace and cut with an X-Acto knife. Add terrazzo shapes.
- Cover with wax paper, and gently roll to smooth the surface. Careful not to add too much pressure and distort the shape.
- Bake the terrazzo jewelry holder and lid on a baking sheet lined with wax paper or aluminum foil according to the instructions on the polymer clay package.
- After the clay has cooled, add two coats of gloss glaze.
- Hot glue the wood ball to the lid as a handle.
JOANN HACKS:
- Polymer clay can become dirty quickly; wash hands, rolling pin and tools when switching to work with a different color.
- After baking, you can lightly sand minor imperfections from the white clay. However, you should test before sanding terrazzo pieces, as some colors of polymer clay will leave a rough finish when sanded.
- Save the cut-off portion of your terrazzo slab, and bake. This piece can be used for sanding tests and testing the gloss varnish.
