Ilene Mahler asked about this purple glaze.
This purple is a cone 6
The firing ramp on this is probably important -- I have only fired this
once.
Here is the actual firing ramp
*ACTUAL FIRING RAMP */*note: kiln lid was cracked open for 14 hours of
firing. it was 1900 degrees when Jen closed it. My bad. Hence the ramp
was slowed to about 150 degrees per hour for 14 hours. Maybe more*/
*Ramp 1 -- 200 degrees an hour up to 2100 *
*Ramp 2 -- 100 degrees an hour up to 2232 -- hold 8 minutes*
*Ramp 3 -- drop at full speed to 1800*
*Ramp 4 -- 100 degrees an hour down to 1300
-- END OF FIRING --*
