Fired at 350F/hr to 1600F and held for 15 minutes. Frit 3134 is still expanding. 3602 and FZ16 are off-ramp. F-75 is starting to flow. Gerstley Borate has suddenly shrunk. Frit 3110 is demonstrating its wide range, slowly softening more at each temperature.
Fired at 350F/hr to 1550F and held for 15 minutes. Frit 3134 is still expanding. 3602 and FZ16 are going to be off-ramp by next firing.
Fired at 350F/hr to 1650F and held for 15 minutes. FZ16 has turned crystal clear and spread out across the runway (has low surface tension). Frit 3110 has so much surface tension that the flow can be lifted off the tester. Since 1600F Gerstley Borate has gone from unmelted to passing all the rest!
