I've got another free and cool tool for you today: an Excel spreadsheet that you can use to plan and record your glass firing schedules.
The spreadsheet will estimate segment and schedule completion times, record your notes and pictures, and more.
For those of you familiar with older versions, there are some important improvements to this new version – including much better handling of your kiln's limitations on heating and cooling rates.
