Lauscha Annealing Schedule is from Carol Anne Beckman who worked at the factory for years.. Recently Lauscha has tested it's colors for compatibility with Effetre and many people are successfully annealing at Effetre temperatures. If you run into trouble mixing several things try this schedule!
Per Carol Anne: When mixing Lauscha with Effetre and other 104 colors you need to anneal a little more conservatively and sometimes a little higher than usual. Also the bead needs to go into the kiln glowing hot. This schedule is from From Carol Anne Beckman (Who worked at the Lauscha Factory at the time). You can also try your own schedules depending on the glass you are using. If you are using silver glass you may want to anneal at a lower temperature but longer and slower on the way down.
Annealing Schedule Lauscha
1. Ramp up as fast or as slow as you feel necessary to 980 degrees fahrenheit.
2. I do not have a separate temperature for soaking and annealing. I use 980 Degrees Fahrenheit for soaking and annealing.
3. Your program should be as long as your working time, plus a minimum of 2 hours. The 2 hour time must be increased if your beads are bigger than 4 centimeters. The guideline that I learned is 1/2 hour annealing time for each centimeter of bead size with a minimum of 2 hours.
4. So, a bead that had a largest measurement of 6 centimeters would need to be annealed for 3 hours.
5. After the annealing segment of your annealing program, you want to take the kiln down to 800 degrees Fahrenheit at a rate of between 60 degrees Fahrenheit to 100 degrees Fahrenheit per hour. The range from 60 degrees to 100 degrees per hour is in case you included a bunch of strange stuff in your bead and you want to baby your bead during this part of the annealing cycle...
6. Then, your hold time at 800 degrees Fahrenheit(step 5) is going to be the SAME as the amount of time you annealed your beads in step 3.
7. After holding, take your beads down to room temperature at a rate of 60 to 100 degrees fahrenheit per hour, depending again on how much strange stuff you mixed in with your bead. For more strange stuff, slower.
