After visiting the Nethers Flint Farm and digging some chunks of Flint Ridge Flint, I wanted to cut the chunks into slabs. I won’t end up using the slabbing saw very often, so instead of buying a more expensive lapidary saw, I choose to go the wet tile saw route. I made some modifications to the wet tile saw to hold the rock in place and allow me to cut a uniform thickness slab on every pass. It worked much better than I had expected it would, so I am pleased with it. I wanted to heat treat some pieces of flint to see how they might change color, as some flint will do. The Native Americans would heat treat some of their flint to make it easier to knap and it would sometimes change color.
I heat treated the flint at 250 degrees for 2 hours, then an hour at 300, 350, 400 and finally for 4 hours at 450. Some pieces didn’t change color, while others gained a pink/reddish hue.
