Please if anybody sees anything that looks crazy or wrong just let me know since i am a totaly beginner at this. I just do what feels right. I have no knowledge to back up my actions.


I have spent many hours watching this picture thinking two things.

1: How does he mortar around the oven door if he places the soldiers so close to the door? Is he using the door as support or not? Also if he uses the door frame as support why is the frame not as far into the oven as the soldiers?

2: Is he even using any buttress? There is no room for insulation as buttress at least from what i can tell. When looking at the mobile ovens like this it seems there is almost no insulation at all ???

Another picture where you can se on left side of oven door it seems that first soldier is really close to the door.

There has been some discussion of insulation of neapolitan ovens and here might be one idea. The leca stones in the background? I guess he must use it for something right.
I think i have spammed my own thread:)

Tom,

I also saw those same pictures on facebook, but canít recall where I saw them.  I donít want to derail this thread, but if you want me to look for them I will.  I think Raffaele Vassallo pictures are interesting if you have facebook.  https://www.facebook.com/raffaele.vassallo.9/photos_stream

Faglia,

I am also researching allot about Neapolitan oven's, i have some interesting pictures, but i think the isolation is done in some type of porous brick like this picture.

It is most likely chunks of tufa.  Going by TxCraigs, it is a minimal insulator.

Tom

Did you confirm that Craigs oven was insulated with tufa?  Mario Acunto has changed the gallery on their website but at one point showed the ovens being insulated with a  cast product of some sort that looked similar to perlcrete.  I thought maybe it was a concrete with a tufa aggregate..

No, but every picture I have seen that is what it looks like.

I wish those pictures were still there.  It basically looked like they built the ovens basic form out of the large mesh first, then put the insulation on as a castable or maybe even gunnable.  Definitely not slabs of Tufa hacked to shape like the other Neapolitan builders I've seen.

I could see where they would use a castable with tufa as aggregate.  Regardless, it is still not a very good insulator, I would consider it to be mass, not insulation.

It's a cement-clay mixture.

Yup, that's been my feeling for a while now.  As I have explained before, it even explains how the Neapolitan vent would cut fuel consumption.

I love when people remind me I'm not crazy.  Thanks Craig!

So it's probably an expanded clay like they use in hydroponics:

The shell of the structure is steel.

And in lightweight concrete, that is what is used for modern CMU, not "cinder", but it is still very dense compared to perlcrete.

There were a lot of pictures in this article but I guess they took most of them down. It was of his factory and had a lot of pictures of ovens being built. Maybe he didn't want other people knowing how they were built. http://www.dissapore.com/cucina/stefano-ferrara-si-fa-presto-a-dire-forno/
