Carbon FOAM from bread - DIY and avoiding foam, a new alternative?

If you bake bread at high temperature without oxygen present you can create CARBON FOAM. 

It’s strong, light… I think porus though? It’s also magnetic slightly… some have tried magnetics before to reduce water surface tension… and had that create a delam problem. Still… definately worth investigating anything that helps develop foam at home. 

Is it economical? Not sure. Start with some moldy bread from a supermarket, bake and glue to form a blank…

eventually move up into increasing the yeast to press into a mold? 

I really don’t like foam because it’s a pain to ship and get in some places, plus the environment cost of course so I find this exciting. If I had an oven I’d try it myself but at the moment I’m living in Asia… so a thing to try at a later date

edit: To actually do this you only need to reduce the air in the burn - you don’t need full oxygen removal as flames can do that for you. Thus, simplest way to try it is - put some break in a old baked bean can and close the lid. Then chuck it in a fire or a very hot oven. Although there’s some gap at the top the oxygen is vastly reduced. I’d try it right now but I’m in a very urban area with no oven. 

I’m thinking 10ft by 2ft toaster , 3 1/2" thick …maybe post some pics during the build.

Get a Dutch Oven.  I’ve cooked biscuits before in a Dutch Oven on a cow dung fire.  Would probably take you the rest of your life to bake enough biscuits for a 9’6.  Just keep some butter and a jar of strawberry jam around in case you get the munches.

I shaped a board out of bread once, but the gulls ate it.  Then I tried pop corn but I kept slipping on the butter.

Way too much microporosity and water absorbtion, which equals major problems if you get a ding.
