Materials needed:

Tumbled 1/8″ tempered glass

Mica paint

NO-Days Groutless Mosaic Adhesive (black)

Pendant Bezels

Hot Plate or Mug Warmer


Step 1 – Painting the Tempered Glass

Tumbled Tempered GlassBegin with tumbled 1/8″ tempered glass chunks.  The tumbling step is done in a rock tumbler with grit.  This is an important step, the tumbling gives the glass a frosted texture that is excellent for mica painting.  In addition, the edges of the tempered glass pieces are rounded and softened during tumbling so they aren’t sharp anymore.  Make sure your tumbled glass is very clean, you’ll need about 1tsp of tumbled glass per mica color.  In this case, we are doing all 8 colors.

Add the tempered glass to your mica paint, either in the paint pot, or a separate container.  Shake to cover the glass completely.

After firing, wash excess mica off in alcohol and spread bits out to dry.

Step 3 – Creating the Jewelry

Cut the Groutless Mosaic Adhesive to fit into the pendant bezels.  I’m using two very small bezels for earrings, and two larger ones for pendants.  You can also use the clear adhesive for a completely different look.

Now, if you are so inclined, you can add jewelry findings and make complete jewelry pieces.  This is a really fun activity for parties or make and take events, simply have the glass prepared ahead of time.
