Motor oil, molasses, mustard: yes. Toluene, xylene, iodine: no
Ever wonder what chemicals are OK on your PVC SIB? Wonder no more. Toluene is a component of gasoline, so make sure to wipe up gasoline spills promptly on yer SIB. Motor oil? Don't worry about it.

Yeah pretty sure you are right, otherwise petrol and a few other very basic chemicals you have at home would make TNT.... Not great to have being sold by the gallon to all comers

Toluene is not that hard to get hold of really 
There is a basic methodology (??) here;
Trinitrotoluene - Wikipedia, the free encyclopedia
Which i would suggest is probably beyond most peoples basic explosives manufacturing capabilities.......

Could be just concrete (some ) depth charges had concrete ballast to make them sink a bit quicker

As did many test munitions whilst calibrating bombing sights or just for practice drops. Mind you .. Its supposed to be impervious to water .. hence the depth charge application .. and it doesn't look like concrete

Try taking a bit and lighting it? 
If it burns, it may be TNT, if not, probably concrete.........

Don't think it's concrete either. And the aircraft was returning from a patrol when it crashed, not a practice run...
Quite a remarkable machine to drill into a hill and have some aircrew survive.

Timescale wise I'd be surprised .. but stranger things have happened .. they still get pulled out of the Thames mud and Clydebank every other year

Just been sparking to one of my old relatives in the village who was in the merchant navy during the latter part of ww2 as a gunner thought I'd ask him about the stuff
, he recons that Torpex is what a lot of depth charges & torpedoes were filled with but to get a slower explosion to give a greater shock wave
it was mixed with all kinds of stuff such as wax & raw aluminium powder .
