Firebox Cracks

Took these pics last Thurday. have a few cracks starting in my Big Joe firebox. Some are very fine– others, more pronounced. Just posting as a reference so that I can refer back to how long the box remains useful before there is a need to contact KJ for replacement.

I don't think it's high temp cooks as much as high temp shutdowns. I do not cook at extremely high temps very often. I have done a few high temp cleanings at the end of cooks. Anyway, I have started to leave the top vent cracked a little when shutting down. Before then, I would just close everything up tight. I'm guessing that contributed to it.

... My firebox is basically in 22 pieces LOL  

 

It works just fine, just dont lift it until the new one comes in.

You could use refractory cement to fill it in and keep cooking or just keep cooking anyway i had cracks in my firebox like yours and was fine for many years

 

That's been the plan all along. The advice to lift it is a little concerning. Had never thought of that– and, I like to clean the bottom of the Big Joe from time to time. Most of the cracks are hairline and just started. I'm certain I'll have months and months of cooks on it.

I found a crack in mine the day after a pizza cook, I did this to it.  The new one is in the garage ready for any emergency need.  This is has working well for nearly 6 months, no sign of failure.

I used SS lock wire, I'll add that the ceramic is much harder than I imagined and it took some time to get all of those holes in in there!

      Does anyone have any experience with grilling whole squid? I toured my local "international" (their term) grocery store today and one item I saw was fresh whole squid. 
       
      I'd like to take a crack at grilling it, but don't want to waste money winging it. Any tips/guidelines you have would be appreciated! Happy grilling

      All,
       
      I am new to the site and messed up the location of my post by initially putting it in the introductions section. Below is the link to that post.
       
      I am looking for ideas on small cracks forming in the firebox of my New Old Kinuura Yaki #5 Kamado.

      Hi all,
       
      I am new to the site, but have loved reading over the last few days. I have owned a Kinuura Yaki #5 for about 3 years now, and it has lived at my FIL's house. Since this is the case, I am still a kamado novice! Finally I was able to bring it home after a long road trip! I know this specific kamado was purchased out of a Pachinko Palace in Sacramento many years ago. I am now the second owner of it. All things considered, this piece is in fantastic condition everything is together and in great working condition. 
       
      As I was packing the kamado for the move, I noticed the firebox is starting to crack. I have seen tons of restorations on this page and know this fix is feasible. What I don't know is if this would be a good point to take the firebox out of the kamado fully and risk more damage (it seems to be cemented in place around the upper rim where the ring sits?), just to leave it be completely and see if it continues to crack, or just try to do a patch job on it while in the kamado. 
       
      What are your thoughts?

      I have a question for the community about fire construction and how much charcoal I should be using when I set up a cook. I have a KJ Classic III and have been using the SloRoller for all of my low and slow cooks.
       
      On some of my larger cooks (one pork butt, a full brisket, and then two boneless pork shoulders) I have burned through all of my fuel before the cook was done. I filled the standard KJ ash basket with charcoal and then light it up with one KJ firestarter. I was smoking everything at around 250F and followed the heating method described by SmokingDad BBQ on his YouTube channel (it worked well!).
       
      Does anyone have an image of what their charcoal looks like when setting up for a 10lb brisket or pork butt?
