Uniface, I thoroughly believe in it. Water has a lot to do with flakability especially with material like quartzite, argillite, rhyolite materials. Jack cresson has also studied this on thee types of...

Originally Allegheny & Westmoreland Counties. Then Montour for a while ; now Clearfield. Helderberg was everywhere in Montour Co., but so full of intersecting seams it was almost unworkable, and...

Woody, I would agree you are lucky. I can send you a box of Argillite spalls if you really want a challenge. I would also agree that on high grade materials water on the surface or even a soaking will...

Look in the Scientific American 1987 for an article entitled The Fracturing of Glass by Terry Michalske and Bruce Bunker. The article explains how water molecules act as chemical wedges to promote...

I thought I had seen an improvewment in some of my stone if it was soaked for a few days, so I asked Richard Dobe, a top knotch knapper at the Bandera Knappin what he thought of the idea. Without...

I definately agree that water helps some cherts. Blue/gray flint hills chert from east central Kansas never works better than the moment you get it out of the ground. Let it dry out and it is harder...

A few more from the knapping forum to keep scattered observations together : I'm not saying water treated flint works as well as heat treated flint but it does work better than raw, dried out flint....

Water definitely helps rock. I have a video of Jim Redfearne saying this as he worked a rock he just picked up out of a creek (so it had been there for centuries I suppose). I've also tried it...

Well, I often keep unheated bifaces of Edwards Plateau in my aquarium. The fish don't seem to mind at all. It seems to not only change the color, prolly due to the saturated water content, but it also...
