Does anyone here use vermiculite fire bricks like the ones in the link?
If so, upsides and downsides to them? I've heard they're a bit more fragile so that would be a concern as I burn both wood and coal in my Squirrel and I wouldn't want to crack them by jamming in a log.
Any advice would be appreciated.
