Another shipable core

Materials, details: We are primarily looking into castable materials, though we have some ideas for using board-type products as well.

I can not see how plain board materials, while cheaper could possibly hold up to the rigors of a burn tunnel.

I have seen a pressed Vermiculite Board material. It is awesome! It can be easily cut and shaped with simple tools. It has awesome fire/heat/insulative properties. It could be made in thicker sizes and cut to a round shape or even custom made to the round shape of your burn tunnel. For a product with a larger production this is definitely a technology worth considering.

I like what I see on the http://www.dragonheaters.com/ website. It is worth a visit to those who want to make this into a business, or who want a working product to buy.
