Portable pompeii oven

[zidaane]

I'm experimenting with a mold based portable pompeii oven designed to be ultra light. I'm curious if anyone tried fire clay mixes designed for extreme lightness.
I'm not really concerned with durability or heat retention.

The project is detailed here: bambino

But basically looks like this

It's really small- 26" wide and 13" high.

Any thoughts appreciated.

Re: Portable pompeii oven

what's the progress on your oven? I have been researching this topic for the past month or so and would very much like to know your answer.
