I picked these up out of from an abandoned storage locker. I know they are "gray ghost" variety, but how did they obtain such patina is my question? They look like they have river polish?

SH told me a while back that he tried experimenting with glass trying to get some type of patination with no luck. I've seen old bottles, 40 or 50 years old, that already show some signs of frosting but I don't think those Grey Ghost are that old. No clue to what chemicals could be used.

It's my understanding that to modern knappers that make copies of high $ type points, ,,the "patina" is as
important as the knapping process itself. It's a crucial factor in defrauding the victims.

Residue from chemical mixes that no one ever heard of, cooking off some concoction of limestone produces
5000 years old scale right in the kitchen

True story, one year ago.
Richard Chrisner paid $400 for a corner tang found by one of his 'regular' diggers who he knew...the guy's MOTHER was with him and swore that she was AMAZED at seeing it insitu...
Next week, R showed it to Dwain Rogers...D was SHOCKED...He himself had knapped the point and sold it at a flint show as a reproduction...
The point had a GREAT scaling on some of it...It would not wash off or even break off with a razor
blade.

In desperation they went to the garage and tried TURPENTINE.....it melted off

For starters, I'd never, ever pay that much for a point. I paid "ghost" money for these, along with about 2 dozen authentic arrowheads, for $80.

I had someone from another forum state that very same thing Redman, and the funny thing is, the abandonded storage unit these came from, once belonged to a man that supposedly traveled the world. I'm going to hope & wish that there is a chance of them being authentic, but until someone proves otherwise. I'm going to try and post some close ups, of the riverwash patina on these things, for they definitely don't look modern.

Well given the travel aspect of the big ones, maybe there is some hope for authenticity.
