: Are you using a specialty adhesive for your foam sheets? Would cheap & widely available ABS plumbers cement work?
I have used a hot glue gun to stick together foam pieces for other types of projects. It works well and is quick. I imagine that I would use the same method if using a clay-based casting material that did not shrink.

I don't know about plumbers cement as it is actually a plastic welding type chemical. I used standard Elmer's white glue and it held together well enough to place the cement around the form. This time though I intend to use Barge cement which is more of a contact cement and it should be more durable of a bond.

I gave carpenters and school glue on some EPS chunks, It appears I laid it on too thick and should have let it tack up much more before sticking together, where it did cure/dry on the outside edges the bond was more that sufficient as it was stronger than the foam. As one of my favorite youtubers likes to say "A little dab will do ya, a big gob will screw ya!"
Playing with the foam reminded me how much I hate this stuff, If I play with it again I'll be making a hotwire cutter first and probably some use spray adhesive also.
I built another form this time of cardboard & tape, my mixture is self supporting at room temperature in less than 2 hours, so it should work.

Cardboard and tape worked well for casting this, I just need to add a little additional support on some of the longer spans. Casting in layers like I did will hopefully allow me to easily recast any piece with an altered mixture. This time around I painted between layers with liquid castille soap instead of vegetable oil and I'm happier with the results.
Some cracking shows my mixture needs some adjustment, this cracking was not present with earlier casting of simple ~1" thick tiles. The cracking is not so bad that I can't test fire it. I'll give it a try tonight.

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
