I put down the Vermiculite layer a week ago. 5:1 ratio with cement, seemed to be the right amount of water, kept it damp etc. As I posted before, the Vermiculite I got was kinda chunky (4-8mm diameter or up to 0.3 inches). I thought I'd read that you need the chunkier kind because it insulates better, but now I can't find that reference anywhere.
I stood on the layer to test it, and while it is firm, you can compress the Vermiculite particles with your thumb. Or pull them off. Is this really the material I should entrust the whole weight of my oven to?? Is it going to hold up? Has anyone made an oven on a layer of Vermiculite this chunky before or did I get the wrong sort? Or is Vermiculite always like this?
I'd really like to know now, before I build the oven and it all sinks in and falls down...
