So you're saying the bricks that are close enough to an actual (not teensy) fire will melt/spill/spread? Why is that such a big deal? I mean, yes, it's nowhere

So you're saying the bricks that are close enough to an actual (not teensy) fire will melt/spill/spread? Why is that such a big deal? I mean, yes, it's nowhere near western building codes, and if there is a non-trivial fire, you need to get out, fast. Much faster than with most typical building materials, though the bricks won't come loose instantly, and that has to do with thermal mass, conductivity, temperature and amount of heat. Note, a match will not do, if painted. A blast furnace will, but I do not see the relevance. Yes, I may have overestimated how much fire the bricks might survive, in my first comment, but I'm not saying the building would withstand a fire - the main point is, that it's more resistant than EPS cladding, couches and PVC flooring, so not as dangerous as it might seem.
