Firing Schedules

Full Fuse Normal Small Project
  1. *600 – 1510- 10
  2. Full – 1050 – 10*
  3. Full*a – 850 – 10*b
  4. 100 – 100 – OFF
  1. *If you have a thick or multi-layer project, you will want to slow this down from 600 to 300, then up to 1500. 
  2. *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..
  3. 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.
  4. 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

 

  1. *600 – 1425 – 11
  2. Full – 1050 – 10*
  3. *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

 

  1. *300 – 1300 – 10
  2. *Full – 1050 – 10
  3. *Full – 850 – 10
  4. 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!

  1. 9999 – 190 – 3 hrs
  2. 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.
