"Fire Free" slate roof material

I have a project that needs about 10 sq. of a mix of black and grey. Does anybody have some in their bone yard? I am in Oakland Ca.but can handle shipping, etc. thanks

So, does anybody have any?

He's not talking about a natural stone product. Fire-Free was one of the cementitious products.

Most everything on the west coast is going to be from China. That is not good or bad necessarily, but you have no assurance that what you get will be of top quality, or any quality for that matter. The one thing you might have going in your favor is that there will be no freeze thaw cycles to mush everything up in a hurry. If you don't know slate, you had better know your slate supplier! good luck with that one.
