This is like very similar to Indiana Hornstone only smaller and often with centricular banding or other patterns. Slabs typically run 4 to 7 inches longwise, often round and we are sawing about 5/8" thick. Email to get in line for this rare stone. It requires no heat treat. Please let us know what lengths, widths and thicknesses you desire. Also, we are sawing pressure flake slabs of Alibates ... yep, Alibates! Pricing is not established. Email to get in line for this fantastic stone. In ancient times, it was traded to every state in North Amercia, the American Indians loved it so much!

It is about a 12 hour drive not including load time. This time, the brakes went to mush about the time I got back to Missouri! The 4-wheel drive truck is tough but this was a serious load! So into the shop next week. Next Jim Spears will go to work, spalling these beauties into great pieces for you! He takes great care to make as consistent size and thickness as possible and remove bad material, cracks, etc. Jim is expert at spalling with the grain of the rock and making minimal waste. I have learned that spalling is an art unto itself! The next step in the process of producing knapping rock will be to heat treat it. We use a kiln, medium size because I have heard a lot of discussion about problems with rock not getting a "good heat" in larger kilns. Don't know if it is the fault of the kiln or just that people get in a hurry. But anyway, our kilns hold about 150 pounds at one time. Then I raise the temperature very slowly, have a good hold time and bring the temperature back down slowly. Depending on our personal schedule, a load takes from five to seven days to complete and be ready for you to chip.
