Re: Roy Johnson's Rock in the Photo Gallery
Thanks John, I have to disagree because I checked with a local rock shop and was
told that it was most likely rhyolite. The matrix is harder than glass and the rock itself
is heavier than glass should be. I slabbed it about a week ago and have to agree with
you that it is interesting but probably worth little. If it was birdseye rhyolite it would
be much better.
Thanks again for responding,
