We had trouble last firing with sand making it's way into the first chamber. The problem lies in the fact the fire brick expands during the firing and pushes out the cob insulation, leaving a small gap between the firebrick and cob insulation. We think mice made their way into that gap between the firebrick and cob. Either way last firing sand kept pouring into the spy hole every time we opened it last firing. Some what aggravating to say the least. I'm not sure this is a permanent solution but this is what I did today:
I cut out the cob above the spy hole and cemented a brick up against the arch. I'm not sure the arch won't push out the brick and leave a gap again, time will tell. This should hold for a little while at least. I still need to fill the rest of the space back in with cob, but I think I can find time during the first day of firing to take care of that.
Next we rebuilt the bag wall.
We have been finding time to make pots though. Christy took a couple days off of work and with Sheridan's help has really been cranking out the platters. I think she has made more platters this week than she lost in the kiln shelf disaster of last firing. So maybe the kiln shelves falling wasn't all a bad thing?
I have to say I feel as though I've been slightly less productive. Not that I haven't been working long days mind you. I did make some teapots which was fun.
Several very long days of potting and then a slew of refires from behind the bag wall of kiln shelves we ended up with last firing.

aww wow, looking good, that's some turn around for this week.. well done!!
Sounds like you guys are in the groove. So long as you keep it on the tracks, everything will be good, I'm sure. It's at times like this when I sometimes forget to listen to that still small voice in the back of my head. Keep your ears open and good luck.
