And it seems to support my theory that there is something special about spittle as the Wet: "Wetting the stone with saliva creates even faster results as this contains proteins that thicken when pressure is exercised."

I was somewhat surprised by the saliva claim, but it seems to be corroborated -

(TLDR: Human saliva is a non-Newtonian fluid across the tested range of shears)

Thanks for posting this - very interesting and well researched. There was quite a "grindstone" industry here in Atlantic Canada as well, but its all gone now.

An old thread here http://followingtheironbrush.org/viewtopic.php?f=31&t=2843 about my trip to the TOS quarry.

BTW still finding TOS & WoA pebbles on the River Ayr shingle banks although the security people at Glasgow Airport did question why I had more pebbles in my carry-on than changes of clothes !
