I actually studied fire engineering, so rather than a dare, I've actually burned loaded concrete/steel beams, and connections in giant furnaces that get a lot hotter than your match to evaluate their fire performance.
I don't think you're listening to what I'm saying about the common air temperature around small fires (auto-ignition of hot gasses at ~600°C is common) and the melting temperature of the binder in these bricks (150°C max).
It's not about ignition of the PE, its about cohesion of the brick PE binder (and thus the sand) at higher temperatures. Your painting this brick that will lose cohesion will do exactly nothing for the performance of the brick.
I dare you to think about it critically, instead of making useless dares that don't address what the other person is saying.
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.
