I was just burning a normal standard match and I observed visible liquid running down the wooden shaft as the fire burns and consumes it, what could explain such phenomenon ? could it be that the wood "sweats" when it's burning ?

    $\begingroup$ In most cases this is just [molten] paraffin which the match stick is impregnated with. Paraffin is used to stabilize and prolong burning. $\endgroup$ – andselisk Jun 17 '19 at 19:12

    $\begingroup$ Wood does sweat in certain circumstances, but it has to be wet in the first place, which the match wood is definitely not. No, this is just molten wax coating, like andselisk said. $\endgroup$ – Ivan Neretin Jun 17 '19 at 19:14

    $\begingroup$ oh thank you. I thought somehow the little water inside the wooden components is coming out to the surface and vaporizing as it's burning so for a split second it's visible. $\endgroup$ – Thesnake123 Jun 17 '19 at 19:16
  • $\begingroup$ If the liquid on the match sizzles like a drop of water on a stove, I'm prepared to bet it is indeed water. ;-) $\endgroup$ – Karl Jun 17 '19 at 19:52
  • $\begingroup$ Water surely leaves burning wood and recondense. $\endgroup$ – Alchimista Jun 18 '19 at 10:48
