42INTERMEDIATE MODE:Keeping a logThere is no “one program fits all” firing schedule for kilns. Even supposedly identicalkilns behave slightly differently. Plugging the same kiln into different outlets in yourhouse may also alter the firing schedule you need. Additionally, different size projects ordifferent colors of glass will react differently, necessitating changes to your firingschedules. It is therefore very important for you to keep detailed firing logs whenever youdo a new project or change any parameter in an existing project.As you gain experience using your kiln, you may find that you need to use the “add holdtime” or the “skip step” sequences (see page 25) to get exactly the results you want. Ifthis is consistently the case for your particular project, you may want to generate a userprogram, written to your desired specifications or modify one of the pre-programmedfiring schedules.Changing Pre-Programmed Firing ProgramsIt‟s a fairly simple process to modify any of the pre-programmed firing schedules to suityour specific needs. If you are relatively new to fusing, or to the use of computercontrols, however, we suggest that you read through the manual and copy one of theprograms in the manual, modifying it as you desire. Once you‟ve test fired the program afew times, you can either leave it as a user program, or use the new program as areference to go back and modify the preset program.In all instances, keep a log of your firings, especially when you make changes, so you‟llbe able to track and or troubleshoot when you have unexpected results.Pages 16 through 23 outline the procedure for programming, or modifying the programsin the kiln.
