Fused Glass Coaster

A fused glass coaster overlaid with stacked colored glass squares separated by stringers, fired in a glass fusing kiln.

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

This project has been made from COE 90 glass, it can also be made from COE 96.

The coaster dimensions can be varied to suit your glass kiln.

Squares may be color co-ordinated or a selaection of random colors can be used,

Fusing Supplies:

One sheet of clear fusing glass.

Multi-colored glass squares.



Shelf primer or thinfire paper .

Fusing glue.

Glass fusing kiln.

Fusing Instructions:

Step 1. Cut two 3 3/4 inch square pieces of clear fusing glass.

Step 2. Cut 16 x 5/8 inch color squares.

Step 3. Cut 16 x 1/4" inch colored squares.

Step 4. Cut six stringers 3 3/4 inches long.

Step 5. Stack clear layers on top of each other.

Step 6. Lay and glue stringers evenly across clear squares so as to form 16 squares.

Step 7. Place stack on prepared kiln shelf, stack colored squares between the stringers.

Step 8. Place shelf in fusing kiln and fire to this suggested schedule (may be varied to suit 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°C) down to 700°F (371°C)

5 AFAP down to 70°F (21°C)

(AFAP* as fast as possible)

Step 9. Remove from kiln at room temperature.

Check for uneven edges and cold work with table top grinder.

If required fire polish after grinding.

At completion of the process you should have a nicely fused colored coaster.

Repeat process to make multiple coasters.
