We had a discussion on chemistry stations. This seems more like medicine (probably out of grinding herbs into teas or something). It seems that is the focus of chemistry that Red has in mind. I was thinking other stuff but its still a bit to early.

On a side note, I agree with the comment below about finding potassium nitrate on the walls of caves. I remember that sulfur was also added to the game (for the sake of making TNT) that the id code for is was taken from cobalt. So cobalt was replaced with sulfur. We still need sulfur and potassium nitrate to make gunpowder. This stuff should be placed on the surface. or cave walls as suggested.
