MCB Posted December 14, 2022 Report Share Posted December 14, 2022 Hello, I just got my first test pieces out of a glaze fire in a new kiln, and need some help in directing me to fix some problems. The kiln is an L&L easyfire E18S-3 with a genesis 2.0 controller. I ran a slow glaze program to cone 6, with a 1 min preheat, no hold, and no controlled cool down. I now realize the slow preset was probably slower than necessary as it took 16 hours. In the future I was thinking of running a slow-medium or medium preset glaze program. Some of my test tiles came out well, but a few were blistered or had pinholes. One of the mugs I glazed came out very blistered, which was on the top shelf. My witness cones look like it got a bit hotter in the kiln than a cone 6. The witness cone 6 on the bottom shelf was more bent than the one in the top shelf. The kiln says both zones maxed out at 2224 F. My questions are... - Do I need a thermocouple offset? If so where do I start? - Should I do a final hold? If so how long and what should I set as the maximum temperature? - Would a slow cool help with blistering? - I bisque fired to cone 06. Would bisque to 04 possibly help with blistering? Any advice is very welcome. Thank you! Quote Link to comment Share on other sites More sharing options...
