The cheese wedges were lumps of phosphorous which burns when exposed to air!!!Leave well alone anything you don’t recognize!!!

How true. Some yrs ago, a farmer found some bombs whilst ploughing his field. I was sent to have a look see, and decided to call out the UXB Team. They recognised the bombs as phosphorous. They dug a hole at an angle in the ground, and placed the bombs in the hole. A fuze was lit, and I started to run for safety, thats when I got yelled at by the O.I.C. who told me to walk away. the reason was, that if I had fallen, twisted an ankle, then I may well have gone up with the bombs. These were phosphorous, and after being blown up, were still burning the next day. I agree, anything of an unusual shape you do not recognise, leave well alone.
