Dave, FB has those tools. Take a look at the FB store, nice items.

Re: Pompeii Oven in Switzerland: the Saga Continues...

Great tools for a great oven! Have you been able to finish the mortar yet?
Sorry, I haven't any advice on this one but will be watching your progress since I think we may want to finish ours off maintaining the round dome look ... once spring arrives (a long cold winter is predicted here).

Re: Pompeii Oven in Switzerland: the Saga Continues...

Nice equipment Frances. I really like that little round peel. I must find one like it!!

And I need to start covering my insulation too.

I think I will follow your lead and see how it works for you.

Keep me informed!

Re: Pompeii Oven in Switzerland: the Saga Continues...

Reading through other people's posts, it sounds like I've been really lucky with the weather this weekend . Started covering the insulated dome with mortar... and I came up with a couple of questions:

- Should I have prepared the vermiculcrete in some way before covering it with mortar? I didn't want to make it wet, because it really seems damp enough already.

- How thick does the mortar have to be over the vermiculcrete?

- How thick should the layer of mortar be over the dome? The insulation underneath is really quite squishy, so the outside has to be like a self supporting shell. I'll be adding more chicken wire with a second (and third if necessary) layer of mortar, but I'd be really happy if I didn't have to put in more rebar...

Any advice would be very welcome.

On a lighter note, I'll add some "before" and "after" pictures of my pizza accessories. So far I've been turning the pizzas with our garden rake ... of course now I'll have to wait for the mortar to cure before I can try my beautiful new peel set.

I'll try heating for longer before the next lot of pizzas and see what happens. (...watch this space... )

I'll be watching!
As usual~!

I'm a junky......

Re: Pompeii Oven in Switzerland: the Saga Continues...

Yeah Sarah, go for it! What's next for you? Insulation?

I hope to get a bit more done over the weekend too, maybe. The weather has turned a bit warmer again and wet... everyone else is hating it while I'm going: Hooray, ideal cement curing conditions!

Dave, I've been waiting for a chance to try those mushrooms ever since I read about them. Thanks for the advice, I'll try heating for longer before the next lot of pizzas and see what happens. (...watch this space... )

Re: Pompeii Oven in Switzerland: the Saga Continues...

Eleven pizzas - cool! And bread ... still just a dream for me. I bet Dutch's suggestion about spreading the coals will help. The mosaic finish sounds great, as well as lots of fun to do too! As for heating leftovers, at least you're using your oven, which is more than I can say right now. I hope to ... no, make that WILL ... get back out there this weekend!!

Re: Pompeii Oven in Switzerland: the Saga Continues...

I usually start with a small fire.. increasing it to the "plasma" state over a period of 45 minutes or so. Then I keep it at that state .. probably another 45 minutes. Until the entire dome is clean. From the very top all the way down to the floor. Now my last burn I accidentally loaded a few too many large pieces of wood toward the end. Thinking my dome was never going to go white.They were large pieces about 5 - 6 inches in diameter. So I still had a raging fire when the dome turned completely white. It probably burned for another 30 minutes. I think this may be why I had so much retained heat the following day. That sucker was HOT! Too hot, at first, for pizza!

So you may try firing an additional 30 minutes and leaving the coals in. Then blocking the door. (I've been using bricks.) And try baking your bread the next day.

I can't wait to try bread with the steam method this weekend.
My last loaf was good. But the crust was hard and very thick. Maybe the steam will solve that problem.

Have fun Frances!

And try those mushrooms this weekend if you enjoy things like that.!

Re: Pompeii Oven in Switzerland: the Saga Continues...

Ooops, no I didn't spread the coals over the floor.
Thank you Dutch!

Dave, I started my fire at 11:30, started cooking pizza around 12:30 when the dome had gone clear, still with quite a big fire going. I finished with the pizzas about an hour later. I took out the coals half an hour after that and closed the oven doors. Spreading the coals and leaving them in longer will probably solve my bread issues, but by evening, hmmm...

The meals I've cooked haven't been "fabulous" so far - mostly (and I'm really, really embarassed admitting this ) warming up leftovers: chopping up cooked potatoes and sprinkling them with cheese, that kind of thing. Its like using a Ferrari to do the grocery shopping! And it takes over an hour to get anything warm by then

How does this differ from your routine Dave? You know what, I'm going onto ebay right away to get myself a thermometer!

Frances
When you finished the pizzas did you spread coals out on the oven floor? Usually when baking bread it is a good idea to spread the coals out across the floor to allow the heat to soak into the floor bricks. Then after 30 minutes to an hour or even longer clean the floor and close the door...that will allow the temperature to stabilize throughout the dome. When your floor surface is 550F you should steam the oven briefly, load the oven, and then steam briefly again. Vent the steam about halfway through baking to set the crust! I think that method should serve you quite well!

Re: Pompeii Oven in Switzerland: the Saga Continues...

And by this evening the oven isn't really hot enough to cook in. I don't know, is the heat leaking out the oven floor? Is the rockwool not a good enough insulator? Should I keep the big fire going for longer if I want to cook again in the evening?
Any tips anyone?

How big, how hot, and how long was your last fire?
My last firing.. the oven was TOO hot to cook pizza in. It could be that you might need to fire it longer.

Let me know about your last fire. We can compare notes!

and what are those fabulous meals that you have been cooking?

I wanna know that too!

Re: Pompeii Oven in Switzerland: the Saga Continues...

Oh, I forgot: the final finish will definately be mosaics, with swirling colours and patterns which are currently changing on a daily basis.

And todays insulation song is "I can't get no insulation" by the Stones.

Don't worry Sarah, Springtime will come round again sooner or later...

[Frances]

Re: Pompeii Oven in Switzerland: the Saga Continues...

Hi Sarah,

The first layer of insulation is a double layer of 2" rockwool with a silvery backing - mainly because that was all I could find. Then I coverd it with a layer of loose vermiculite, because the rockwool should not be compressed...

I'm a bit puzzled about the insulation properties of my oven at the moment though: I cooked 11 pizzas over lunch today and had a ball. I have no problem getting the heat up and each one cooks in about a minute. I'm astounded at how well it all works and how good they taste...

But the bread I baked this afternoon didn't brown on the bottom properly. Well, I did some yesterday leaving the coals in the oven and it got a bit too brown - so I took the coals out today. And by this evening the oven isn't really hot enough to cook in. I don't know, is the heat leaking out the oven floor? Is the rockwool not a good enough insulator? Should I keep the big fire going for longer if I want to cook again in the evening?

On the other hand the oven was warm inside two days after firing... I dunno. Maybe I just shouldn't compare my oven with Dave's . After all, I am cooking some great meals in there...

Any tips anyone?

Re: Pompeii Oven in Switzerland: the Saga Continues...

Hi Frances,

Glad to see you're making progress! I can't quite tell from the photos though - is there 'vermiculcrete' under the silver cover (is that an insulating blanket?), or is the silver thing directly on the dome, with something to be added on top of it?

I'm stalled out - too cold, wet and dark too by the time I finish work, and too many other things intruding on weekends - so I am stuck envying the progress of others ...

Have you decided on the final finish yet?

Sarah

Re: Pompeii Oven in Switzerland: the Saga Continues...

I was waiting for them to use some of your ideas!

You know... I forgot to do that.

Ill snap some pics at home tonight and get them posted tomorrow!
