A bit gruesome, I know. But I have a character who is inside a flour mill when it explodes. (Flour explodes when separated and exposed to oxygen and an open flame or spark. Someone ripped open a bag of flour and scattered it through the mill, then lit it on fire to kill my poor miller) He is trapped under the millstone (think medieval watermill) and dies. MC returns to the scene the next day after the fire. (the deceased is her father) I know the wreckage of the fire would most likely still be smoking. The mill itself has blown apart. The bakery next door was partially standing immediately after the explosion but has since collapsed. My question is, if MC were to pick through the wreckage and find the millstone (which she knew her father had been trapped under) how much would remain? He survived the initial explosion long enough for MC to brave the fire and speak to him briefly before he passed. However, no one would have been able to move the millstone without a winch of some sort, so the fire would have raged around his body for a while before they got it under control. Googling tells me crematoriums burn bodies at a much hotter temperature than wood fires burn. So I imagine there would be some bone remains. Would they crumble at a touch? How much do you think would remain?
