I've read lots and lots (on this forum and elsewhere) but please forgive me if the following questions / concerns have already been answered elsewhere.
1. I'm a bit concerned about a wooden sleeper plinth catching on fire (or at least smouldering away). I saw another post that said something like 'wooden plinth should be OK but ensure your base is well insulated', and I have seen photos of an oven where the outer edges of the oven definitely overlap the wood surround of the plinth and the author said it was OK; however, does anyone have any advice on a) whether there is a risk of the sleepers burning and b) how to minimise the risk of this happening
2. Do fire bricks contain any nasty chemicals / substances that might be harmful to health? Or are there any different kind of bricks that could be used that def. aren't harmful to health?
