A Mosaic Glass Coaster Fused In A glass Fusing Kiln

mosaic tile fused glass coaster

Make a mosaic glass coaster in a glass fusing kiln using clear and colored glass

This mosaic glass coaster is made from clear art glass overlaid with transparent colored art glass squares.

After fusing it may be necessary to cold work and fire polish the coaster.

The glass coaster has been made from COE 90 fusing glass, it can also be made from COE 96 glass.

Coaster dimensions can be varied to suit your glass kiln.

Squares can be color co-ordinated or in random transparent colors.

The following items are required to make the coaster:

One sheet of clear fusing glass.

Multi-colored transparent glass squares.

Glass cutter .

Shelf primer or thinfire paper.

Fusing glue.

Glass fusing kiln.

Glass grinder

Proceed as follows:

Step 1. Cut two 1 x 4 inch square pieces of clear fusing glass.

Step 2. Cut 64 x 1/2 inch color squares.

Step 3. Glue one row of glass squares along the top edge of the clear glass, glue another row down the left hand edge of the glass.

Step 4. When the rows are dry begin to lay out the rest of the squares on the clear fusing glass.

Step 5. Place glass on prepared kiln shelf.

Step 6. Place shelf in glass fusing kiln and fire to this suggested schedule (may be varied to suit glass size and kiln type):

1. 400°F (222°C) up to 1225°F (663°C) hold 45 minutes

2. 500°F (321°C) up to 1480°F (804°C) hold 10 minutes

3. AFAP* down to 960°F (516°C) hold 60 minutes

4. 100°F (56°) down to 700°F (371°C)

5 AFAP down to 70°F (21°)

(AFAP* as fast as possible)

Step 7. Remove from kiln at room temperature. Check edges, with this type of design the edges may require grinding if they are very uneven.

After grinding fire polish coaster for a shiny finish.

The following schedule can be used for a two-layer glass project. Thicker glass will require a slower schedule.

1. 300°F (167°C) up to 1100°F (593°C) hold 10 minutes.

2. 350°F (273° C) up to between 1350°F (732°C) and 1375° (746°C), hold for five to ten minutes.

Check to ensure that the temperature and hold time is not distorting the glass edge. If so move to stage three immediately.

3. AFAP* down to 960°F (516°C) hold 60 minutes

4. 100°F (56°) down to 700°F (371°C)

5 AFAP down to 70°F (21°)

(AFAP* as fast as possible)

When cool remove from kiln, the piece should now have, a shiny fire polished finish resulting in a nicely fused glass art coaster.

For variation this coaster can made from opaque glass squares fused to a contrasting art glass base
