Not much... but I'm hoping it is enough to get you started!
Hey, if the fundraiser doesn't work this go, perhaps the next one.
I'm a member of Alchemyprocesses.com, which is how I found your project ;)
I'm pretty damn close to achieving the white stone, should I not falter.. pre-1964 silver coin calx is currently gray. I see white, but SolarSeeker is stipulating it might be Silver Chloride.
Suffice is to say. If I succeed before your project hits the ground, I'm coming to fund you.
Godspeed.
