GoodHouse Posted January 15, 2021 Report Share Posted January 15, 2021 Hi, I’m a new first time kiln owner. She’s a Paragon Caldera XL that’s been fired to cone 6 less than 10 times so far. I noticed along the back wall of my kiln every element has a section where the coils have started leaving marks in the bricks. This is happening with every row along this wall, and only this wall. Should I stop firing for now to prevent making it worse? What caused this and is it preventable? I also attached a photo of a polite frog on my mug handle to thank you for your help.

neilestrick Posted January 15, 2021 Report Share Posted January 15, 2021 Are you sure the grooves weren't already there from the beginning, and you just didn't notice them? I suspect that when the elements were installed and pushed into the grooves that they cut into the bricks a bit. I would not expect them to be able to push into the bricks with enough force to do that just from expansion and contraction during firing, but I suppose it's possible if they're moving and/or expanding a lot. Either way, I wouldn't worry about it. They're not going to ruin the brick, and I would be very surprised if they get any worse. Link to comment Share on other sites More sharing options...
GoodHouse Posted January 15, 2021 Author Report Share Posted January 15, 2021 I can’t say for sure if they were there. Thank you for the reassurance! I’ll keep an eye on them and move forward Link to comment Share on other sites More sharing options...
