Hi Meredith. Sorry to hear
Hi Meredith. Sorry to hear that you had a problem with your piece. I would recommend you try Spectrum’s 8-segment firing schedule (changing step 5 to your desired goal temperature). You can tweak the schedule to suit the size of the piece and the complexity of the design. http://www.system96.com/Pages/FiringGuideF.html
Hope you have better luck after trying the new schedule. We generally use the 8-segment as our go-to schedule (bottom of the firing schedule web page), but the 6-segment is an option that can work well too for smaller, basics designs. Try the slumping schedule posted there, as well.
