To begin with, let's just imagine a small, not-so-cramped room where the only purpose for chairs is to hold apparels and the only purpose of the shoe stand is to be empty and surrounded by shoes strewn here and there. Well, not a very untidy place mind you, and not out of neglect at all. It's just the way we like to keep it. Now there is a good theory in science called mutual co-existence and we strongly believe in it. We co-exist happily with cockroaches(to my dislike though), a couple of breeds of ants(namely red-&-black), the occasional lizards(those which scare the shit out of some people) and the regular pigeons and sparrows in the balcony.
The vessel, it turns out, was too thin to handle oil at a high flame. The oil erupted into flames. It was a disastrous sight to see. The flame was at least 6-8 feet high and the vessel was immediately, immaculately and heroically grounded and taken away from the gas (not by me). The sight was both, amazing and (won't have accepted if I was sure none of my friends would read this) a bit scary. It took 10 minutes (a really long time when you consider the situation) for the fire in d vessel to get extinguish. In the meanwhile, all doors were opened, exhaust fans were utilized and everything, combustible or not, was taken away from the kitchen.
At the end of the inferno, the vessel doesn't look in a reusable condition(though my roommate is optimistic enough we can, with some diligence make it good) and some part of the ceiling will keep reminding me of this small adventure of ours.
Anyways, as it would be etched on my memory for a long time, an advise for you to sim the gas always before going away. I hope you have experiences, but not as adventurous ones as this..
