Looking for flint, obsidan, or anything

[Reed Creek Head Hunter]

I'm in need of flint, obsidian, or anything that I can knapp to make hunting points out of. Been practicing on glass bottles and need something a little more tougher.

I have two large hunks of solid glass, it is easily 5"x6"x10" with the 2 pieces together.
