I'm curious, are there any instructions for curing?  Even if there aren't, just to be safe, I'd probably cure this stone (start on lowest oven temp and then increase by 100 every hour).

I don't know Scott, but this sounds like a waste of fuel.  I didn't cure my stone and didn't have any issues.  I don't think any of the other members have cured either.  If it cracks upon initial use, you can always contact the company for a replacement.  I took mine to 800F+ on the first bake witout any issues.

Chau, cast cement stones (such as fibrament) tend to have moisture in them from the casting process.  If the stones have water in them or are stored/shipped in an environment where they get wet or are exposed to humidity, they'll crack if you crank up the heat. Sure, the company will replace them, but if it's between a couple of hours in a home oven vs. the potential of having to wait for the company to send me new stones, I might toss it in the oven. Am I being overly cautious? Probably- but porous stones are notorious for failing due to moisture expansion- and these, by their density, are incredibly porous stones.

Btw, when I talk about an oven, I'm talking about an indoor oven.  I believe 3/4" fibrament is a 5 hour process, but, at 1/2" I think 2 would suffice- one hour at 150 and then another hour at 300.  Turning the oven on right now, with the temps we're seeing, is probably something most people would want to avoid, but I'm just telling you what I would do.

Scott, the bottom stone weighs 6.61 lbs and is 14mm thick. I am almost certain you can break the stone by hand pretty easy using the edge of a workbench.

The stone could be this one from china.

Some reviews of this stone on Amazon like this one: "The only thing I don't like too much is the maximum rated temperature is 450F. This normally isn't a problem, except that I tend to pre-heat the grill to 500F, and then cool it off from there."
That couldn't be used in the Blackstone oven.

According to my calculations, the density is .056 lb/inch^3. I don't have the specs for fibrament, but cordierite runs in the .09 range,

I just measured the one I have, an it's about 0.07

Thanks, Craig!

So, there you have it. .056 for this, .07 for Fibrament and around .09 for cordierite. This stuff is light. No wonder why so many stones are breaking in transit.

So, what do you think then, would it be an advantage or disadvantage to swap in a Fibrament stone?  I just happen to have had one arrive yesterday - which I ordered back when I first started messing around with this thing...

So many?  ???  It is light but it heats up quickly.  When I swap it with my primo stone, which is twice as thick, it takes longer to come up to temps.  I like this stone.  I like this stone it works.

I don't have an exact count of the members who have purchased the blackstone, but it can't be much more than 10.  2 out of 10 broken stones is a LOT. If 20% of their customers get broken stones, that's huge, imo.

When members have spoken to Axner, customer service has said things like "stones are breaking during shipping all the time."  In reality, I have yet to come across anyone who's gotten a broken stone from Axner. 

I'm not saying this is a bad stone or that it should prevent anyone from buying this, I'm just saying that it's most likely the lightest stone you can possibly buy- and that lightness seems to strongly point towards fragility. Lack of density and lack of strength are almost always tied together in these types of materials.

So, what do you think then, would it be an advantage or disadvantage to swap in a Fibrament stone?

No, no advantage that I'm aware of.  But I would keep the Fibrament stone around, just in case.

Got good responses from Cabela's and Blackstone.  Cabela will send out a new unit.  They will have UPS pick up my old unit.  I will try to rebox it (yikes).  Blackstone called.  They said the valve was right behind the black plastic dial, and he suspected a leaky valve.  He offered to replace the valve and send me a new stone.  He suggested that I could test the new unit for valve function by turning valve on to low, removing black plastic dial, and lighting a cigarette lighter to see if I got any flame.  I hope these units hold up.  The hood support bar on my unit warped after just 15 minutes of flame.  I will post a pic.   Mark

I imagine a light weight stone helps them to keep shipping costs down if nothing else. Though they might give the savings back in breakage.

Did you have the regulator on? What setting were you using?

Do you mean the black dial to regulate the flame on the front of the unit?  If so, I had it on half way for about 10 minutes, then put it all the way up and that's when the flames shoot out.  It happened at lunch time today again.   Mark

Mark, buddy, do we really have to tell you that if flame is shooting out the front of the panel, you shouldn't be using it? Are you really in that much of a hurry to use this oven?  ;D

Mark,
Don't mess around with that valve and do Stone Bros. R&D for them!  "he suggested I have a leaky valve"...f'in duh man!  You have a bent shaft on the valve control due to being severely dropped in shipping and that has disrupted it's seal. And I mean 'severe"..this thing took a hit and....the brackets that hold that valve/dial and brackets supporting the burner to valve junction could now be bent also. So just replacing the valve might not be a total fix. Blackstone should know this...but sounds like they either don't or are willing to take chances with your safety in lue a an easy quick fix.
Cabelas have a better consumer standpoint/policy...."we'll replace it". They have different relationship with Stone than the 'lil guy has if he buys directly from Stone.....buyer beware.

And for all your troubles man...I would return that unit sans the one good stone you do have(keep for spare). And just bunch it together in a damn box for UPS pickup...it's jus going back to Cabellas and believe me, they are only going to put it in their dumpster after Stone Boys reimburse them.

Actually, if I was going to hold on to something, I might keep the heat shield before the top stone. Not a bad idea, though.

Honestly, much like Chau's Forno Bravo screw-up, if I were the company, I'd probably let you keep the broken unit.  You deserve something for your troubles (imo).

 here's a pic of cordierite on top of the Blackstone. Look and feel are pretty similar. Blackstone has a bit finer grain to it. I'm going with it's cordierite

ps....I have NEVER, EVER heard anyone say to check a gas leak with a match or a lighter. ABSOLUTELY reckless advice on their part!!

Keep 'em both.
That shield just lays in the "U" brackets that are welded onto the support box tube bar and probably a through bolt at top aluminum piece; no?   Keep it an double up on the shield.

Btw, I see some extra crappy mig welds on those most recent pics. Some have too much "heat penetration", which leaves surrounding metal brittle and rust prone....other welds show too little "penetration" and that will cause "bond" problems...things can 'snap' loose.   Just pointing out what I see and what could be possible problems down the line.

Warped
That's not going to have an effect until later when the brace separates further away from that back wall and allows heat to escape behind the shield.  One little tack weld placed directly at the midpoint of that bracket(under the center where it is bending) would have eliminated this potential problem.

Also, after looking at this more closely now....I believe an additional "U" bracket should have been placed on the opposite end of this shield bracket/bar and another "U" at the mid point of the box tube arm/bracket to help maintain the shape/integrity of the shield....the shield will probably begin warping/ become distorted before long.

Mark that support bar likely warped from the unit being dropped.  If it was from the heat, more of us would be seeing it.

You are right Scott!  I won't play with fire any more ;)

Bob, the heat shield is welded to a frame that supports the top stone.  Yes, those welds do look suspect.
Mark that support bar likely warped from the unit being dropped.  If it was from the heat, more of us would be seeing it.
I hope so Chau, but the warp is exactly where the burner hits the metal and makes it glow red.   Mark

Mark you are right.  I thought the same after I had looked at the photo you posted again.  It just seemed to fit the theory that your unit was dropped in light of the broken stone and the propane leaking from the front.  Seems as though you may have gotten a lemon.   It is strange that no one else has noticed their bracket warping yet.   ???

Last nites 1st firing of the Blackstone. I used the SI 00 flour using the AVPM recipe. All and all, very happy with it, although I do think the dough got over developed and lost some of it's spring. Did a garlic olive oil pie first, a prosciutto jalapeno, pepperoni onion, and just onion all topped with mozz/prov blend and a bit of parm to finish. I want to try a low hydration cracker crust in this using 00 flour. The one thing I'm not fond of is the rotisserie motor, very weak and stops frequently so I'll be getting a different one for sure

I have an electric one from my grill that I am hoping will fit. The mounting tabs look the same.
