This doesn’t look normal, or good!

I’d imagine this has been goin on for quite some time to get that grease build up.

The ash area was glowing red, I think grate help protect the base from rapid temperature changes

Ive had 4 crack all with stock grate in. 

Do you just get a new Egg altogether?

No they will give you a new base.

And how did I get the build up on the bottom of what appears to be grease? That little hairline crack can’t be responsible for that. Has anyone seen that before?

Yep, it was the crack. Started small, grease seeped through and created the stain. I've had it happen several times.

Ok. Should I stop cooking with it and get it replaced? I don’t want the thing to split on me while I’m cooking!

I think it is actually fine to keep cooking on for the time being.  Just monitor the progression of the flaw after every cook.  The nest will likely constrain the rig from total collapse.  

In the meantime, file a warranty claim, like tomorrow.

The hotter the cook the wider the crack gets. I can’t tell what your egg is sitting on if it’s a wood deck I wouldn’t use it but if it’s concrete or something you should be fine just make sure you watch it.

This is why you don’t vacuum out eggs. It needs the insulation that the ash provides.

Hmm...  if this is true maybe I need to stop

I don’t vac just ash tool. Do what you want! I’m not running ash basket naked anymore. I do love it though should be standard with bge.

Yeah it’s on my deck. I went and looked a little while ago and now that it’s cooled down the crack is hard to see

There’s usually a decent amount of ash in mine. I only clean it when it gets pretty deep

thanks!

ive started using a torch to light the egg. Do you think this could cause a crack with high heat?  I’ve always used Rutland fire starts in the past.  I use the grate and KAB.  Just wonder if the torch could affect the egg with high temp. 

milesvdustin

I think this is why the vision brand kamado come with a small round stone that goes on the bottom in the middle of the fire bowl.

No, torch is fine. Ceramics can/will crack. That's what the warranty is for. It is also why I will never buy a used egg. 

Carolina Q

The KAB had nothing to do with this. You bought a ceramic grill. Ceramic grills crack. Just the way it is.

I sure hope it's okay to keep cooking with it. I have been for 3 or 4 years now. One of these days, I'll get a new base. And I don't have, need or want a KAB.

Just get a new one. One of these days, maybe even I will. 

theyolksonyou

These things are kilned at 2450*F.  A torch or a KAB ain’t got nothin to do with it.  It’s just as JIC said and also why they provide a warranty.

It it seems like the word in common here and several previous threads is “XL”.

No, I've also had my XXL crack.

But, I think you do have a point, the larger the egg, the higher potential for casting flaws. @JohnInCarolina for a fact check.

alaskanassasin

Is there a advantage to not using the grate with the kab? Why risk it?

Legume

My XL has had a cracked base for well over a year and I’ve kept cooking on it (sits over concrete and nothing flammable near).  It’s been fine until recently I’ve found that I have trouble holding temp below 300, it just likes 300-350 now.  I used to be able to stick 230 without any problem, so I’m guessing the crack is expanding and letting more air in.  Who knows, but it’s time to use the warranty base sitting in my garage.

if you have wood or anything flammable near, just replace it now and sleep well.  Fwiw, I’ve only ever used the stock fire grate.

Mine popped with kickash and no grate. I run the grate now.....

Do you think the basket causes it?

No.  What causes is it is the temperature gradient combined with the curvature of the ceramic part, giving rise to tensile stresses that exceed the strength of the ceramic itself.

That and a weak point (flaw) in the ceramic.

The flaw actually lowers the apparent tensile strength, so your comment is redundant.

 ooohh, we have Mr. A. A. Griffith in the house.

if there were no flaws, the tensile strength of the ceramic would exceed design specifications, you orange hatted doosh

My XL is the only one of my 6 eggs that hasn't cracked in one way or another.  I even use a KAB, with a torch ..

Tonight's start up procedure:



Eggs have been popping for years before KAB was even anyones idea.

Griffith has proven to be surprisingly predictive, especially over the past few decades as variational models of fracture have emerged. But I prefer gradient damage models that asymptote to cohesive models in the limit as the regularization length vanishes.

The question at hand is whether or not the presence of flaws lowers the *effective* tensile strength of the ceramic.  Your comment here suggests that you believe that they do.  So now you are just arguing with yourself.

Empirical evidence suggests that I am right.  I love arguing with myself.

I remember reading where they use to recommend using the original charcoal grate with the KAB on the XL.  I believe it was even on the CGS site, but I can’t find it now.  I always leave my original grate in with the KAB.   Here’s an old post where KAB confirms using the fire grate with KAB on the XL.

all of my eggs are cracked and under warranty.      my vision grill has no warranty and has no cracks....hmmm
