Firing Schedules
Full Fuse Normal Small Project
- *600 – 1510- 10
- Full – 1050 – 10*
- Full*a – 850 – 10*b
- 100 – 100 – OFF
- *If you have a thick or multi-layer project, you will want to slow this down from 600 to 300, then up to 1500.
- *If you have a large, thick, or multi-layer project you will want to hold your project longer. I hold my trays for 45 minutes to 1 hour..
- a*Again, depending upon thickness or layering, you will want to slow the process down from a full drop in temperature to anywhere from 50-85 degrees per hour to 850.
- b* Again, hold longer for more complicated, thicker projects.
Float Glass Mosaic
Full Fuse Mosaic Sheet- 1 Layer
600- 1510- 10
Full- 1050 – 10 *
Full- 850 – 10 * **
100- 100 – off
Full Fuse Mosaic On Cut Outs (Glassy Cut Shapes)
600- 1510- 10
Full- 1050- 10*
Full- 850- 10* **
*hold longer for thicker projects
** come down slower for thicker projects
Slump Mosaic Pieces
300 – 1300 – 10
Full- 1050 – 30*a
Full- 850- 20*b&c
100- 100- off
*a- 30 minutes or longer depending on the size & thickness of the mold you’re using. Mosaic pieces that are stacked 3 or more in height should be slumped very slowly or your project will split.
*b- Slower than the full 9999 depending on the size & thickness. We will slow this down as love as 50 degrees per hour
*c- Hold here longer also if it’s a thicker piece or on a metal mold.
NOTE: Metal molds hold their temp longer than glass so you could shock you glass and break it.
Tack Fuse Mosaic Normal Small Project
- *600 – 1425 – 11
- Full – 1050 – 10*
- *Full – 850 – 10
Same info as above for ramping up or annealing down. Temps change with the size, thickness, and multi-layers of your project. Multi-layers include mosaic too.
Slump/Drape Temps
- *300 – 1300 – 10
- *Full – 1050 – 10
- *Full – 850 – 10
- 100 – 100 – OFF
Again, be careful with ramping your temp too high in the start or dropping your temps too fast. If you are slumping on or over metal- slow it way down to avoid thermal shock from metal retaining its heat longer than glass.
NOTE: Metal molds hold their temp longer than glass which can shock your glass and break it.
Fire Polish
Slow – 1300 – 5
Ramp down slowly
*Remember- any texture or embossing will flatten out at 1300. A trade trick is to grind your piece & add a swab of Liquid Luster from Olympic Glass in Seattle.
Steam Cast-A-Lot Casts
Do not steam plaster of paris molds. Both types of molds will need kiln-wash prior to casting glass!
- 9999 – 190 – 3 hrs
- 250 – 1500 – off
*Will throw a good amount of steam so your kiln should have stainless steel parts/ hangers or it will rust!
Fusing & Slumping Bottles
SMALL BOTTLES:
300 – 1100 – 5
300 – 1300 – 10
500 – 1425 – 5
9999 – 1000 – 60
100 – 200 – off
*LARGE BOTTLES:
300 – 1100 – 30
300 – 1300 – 60
500 – 1425 – 5
9999 – 1000 – 60
50 – 800 – 60
100 – 200 – off
*Large bottles should have temps that are held out longer to avoid thermal shock. This is due to the base laying down & creating a thick area compared to the rest of the bottle.
