Re: K79 Oven Build

I agree - once you cook something you officially have an oven! Well done!

Re: K79 Oven Build

The last three days I've had a fire going till about 8pm then shut it down for the night. Each day it burned for about 12 hours. 300F, then 350F, then around 425F. I'll be switching to 6 hour fires for the remainder since I'm back at work. Decided to make dinner in the oven last night. Sweet Italian sausage, red and green bell peppers, onions and eggplant. It was awesome !! I also mixed up some butter, garlic, rosemary, parmesan, and lemon and put that on some Italian bread with some mozzarella.

Re: K79 Oven Build

That looks like what I have used.

Re: K79 Oven Build

Ok so here is the new stuff I found. I was told it's vermiculite but it doesn't say it on the bag. Same company as my last vermiculite that was to fine:



15% of my oven opening equals:



First fire. I found that the charcoal holds a nice 300F heat and every half hour a little wood holds me at 350F:

Re: K79 Oven Build

I started my fire at 5 am and at 9 am the temp was a little over 200F. I doubled the amount of coal I've been putting on and it is now 10 am and I'm at 300F. I'll try and hold it here as long as I can. 1 hour and 100 degrees is considered still slow right?

yes, I would say so. I wondered about the amount of charcoal when I saw the first picture. you can use 2-3x that amount. Just spread it out once it is going.

The thing you want to watch out for is a 100+ degree spike in a couple minutes, which you can easily get with a wood fire. Not so much of a risk with charcoal

Re: K79 Oven Build

try uline (google uline its a office factory material store)for vermiculite thats were i purchased it it is sold for packing and shipping of hazz mat materials due to its absorption the tech guy knew all about it they have 3 grades available i recieved it in 2 days. 2 large bags, cheap!!!!

Re: K79 Oven Build

Just looked at it...that's block fill and the heat transfer is related to ambient temperature through masonry...not wood fired ovens. Don't count on 50% using it as insulated cladding. Like I said, it still has some value, just not as good as course vermiculite...how much is the question.

It's not big deal..you have the blanket on there too.

Ok, I think I'll just go with it. There were some other larger type insulation there but it didn't say vermiculite.

Re: K79 Oven Build

Well I sort of am depending on it for insulation. I mean I have 3" of fiber blanket on the oven, but I was hoping this would also add some insulating factors. Check out post #423... it says it reduces heat transfers by 50%. I hope its ok???

Re: K79 Oven Build

It will, but finer particles will have less airspace between them than coarse vermiculite...greater air space between the particles has a greater insulating factor.

Re: K79 Oven Build

Wow that's very fine particles...nothing like what I have used in the past. But since you aren't depending on it for insulation it should tool out nicely over that blanket.

Re: K79 Oven Build

Light the charcoal at 5 am. At 7 am I was just over 200F. Definitley going slow.



Exciting to see smoke coming out my vent. I'ld say about 95% is coming out the arch. Hopefully almost all of it will with the chimney on !



Here's my vermiculite. Look like the right stuff? The guy at the hardware store knew less about it than me. In fact it was in the back of the warehouse and not even in their computer anymore. I got a heck of a good deal on it

Re: K79 Oven Build

Kingsford is in the garage. Ill use that tomorrow and try and keep it below 350F for at least 6 hours tomorrow.
