Juliagoolia Posted May 7, 2020 Report Share Posted May 7, 2020 Hey everyone, Newer potter, on my 5th or 6th glaze firing, and my first screw up! I'm running a glaze fire to cone 6, with my skutt 1027 electric with a bottom vent. I totally forgot to plug the peep holes until I went in after about 5 hours (so about 55% of the way through a normal 'medium' speed run). It was at 1500 degrees. I never leave plugs out because of the vent. I plugged it, but now I'm totally curious if I've messed up the entire batch! All I can see in searches is referencing top holes, and notes that it's not required when you have a vent... but will it cause damage if it gets up to 1500 without plugging and with a vent? I'm prepared for it to take a bit longer to reach temp, but since I won't be opening the kiln until tomorrow night, and help managing my expectations or alleviating my fears would be great! Thanks! (Also, since I never leave plugs out, I've never seen the red glow through the holes - don't worry, I didn't look directly at it, but I was like, cooooooool.

liambesaw Posted May 7, 2020 Report Share Posted May 7, 2020 I dunno, I routinely leave my peeps out because my clay is gassy. I bet it'll be fine since you caught it before anything started melting. Things might be smoother and nicer than normal, you never know until you open it tomorrow Link to comment Share on other sites More sharing options...

I'll be running a glaze run in a couple of days (just waiting for my witness cones) and don't know what to do. It seems to me most people leave one peephole open for the gases to escape. I don't have a vent on my kiln. It's a practically brand new ~6cf Sandstone Skutt kiln with a sitter. I guess I should follow the instructions...but I dunno?

liambesaw Posted May 7, 2020 Report Share Posted May 7, 2020 Once you have them all on high, you want them closed so the temperature climbs steadily. Until then you can pull the peeps to get things gas off. Link to comment Share on other sites More sharing options...

neilestrick Posted May 8, 2020 Report Share Posted May 8, 2020 I'd leave the top peep open throughout the firing. Oxygen is good. Glazes look better, bisque burns out cleaner. Link to comment Share on other sites More sharing options...
