While in university, I received several flint nodules from Grime's Graves in England.
I had read in a text some ancient knappers went so far as to heat temper flint to improve the molecular density.
So, I put a nice big fat one in my oven, cranked it up to 500 degrees and waited. I'm not sure what I waited for, it's not like a chocolate cake you start to smell or see anything turning brown.
After an hour UPS rang my doorbell. I had just stepped away from my chair in front of the oven window.
WHAM! the nodule exploded, sending a shard into the tempered oven glass and punching out a huge bulb of percussion 5" in diameter that was imbedded in my seatback.
