Mosaic Garden Gazing Ball

Mary Clark-Camargo from Pasadena, Calif., shows how to make an eight-inch diameter mosaic garden ball using several different glass materials. It is vibrantly colored and has a floral motif patterned from passionflower vines found in her yard.

Materials:

For preliminary sketch and color palette:
sketchpad
pencil
all-purpose white glue
sampling of small pieces of glass

To cut stained glass:
sheets of stained glass
cardboard mat
T-square
glass cutting tool
glass cutting oil
glass nippers

For ball:
1 small heavy brass bowl
1, 8" plastic ball (Christmas ornament)
sandpaper (or small electric sander)
Sharpie marker
stained glass cut into 5/8" squares
vitreous glass tiles
small pieces of mirror
multi-drawer storage box
large plastic bowl lined with cheesecloth
wheeled glass nippers
safety goggles
waterproof silicone adhesive
dental pick and tweezers
black unhanded grout
disposable latex gloves
large plastic container
stir stick
small funnel
plastic hair dye applicator
sponges
nylon or soft wire brush
grout sealer
1 gazing ball stand

Steps:

1. Make a preliminary sketch of the design on a piece of paper.

3. Sand the surface of the ball (plastic Christmas ornament) for better adhesion. Make a rough outline of the pattern on the ball using a Sharpie (figure B). Place the ball in a small heavy bowl to use as a stand while working on the mosaic.

5. After finishing the flowers and patterns, start filling the background with field tiles (figure D). It is important to stagger the rows. You do not want the background to be too symmetrical. Always leave room for grout to surround each piece. Let dry.

6. When dry, check the mosaic pieces for excess adhesive. Use dental tools and tweezers to carefully remove pieces.

7. Mix the grout per the manufacturer's instructions. If you cannot find pre-colored black, a colorant can be added. Once the grout has been mixed, funnel it into a plastic hair dye applicator.

9. With a damp sponge wipe off excess grout from the glass. Check for low spots and sharp edges. Using your leftover grout, fill in the imperfections. Let dry again. Gently scrub the mosaic until it is completely clean (figure F).

10. After the grout has cured for four days, apply a commercial grout or masonry sealer. Let dry.

11. Place the ball on a gazing ball stand.
