The granite would be great for petroglyphs! They are
made by striking the rock many times to knock away the
patina in a pattern, unlike pictographs, which are made
by drawing on the rocks. There is an artist here in
Arizona that I have seen do a demonstration with fourth
graders on petroglyphs, during which time they learned
the importance of original petroglyphs and how to
preserve them. I unfortunately cannot remember his
name. I will have to dig for it.

Subject: granite and marble pieces
Hi all
I have access to lots of polished granite and marbles
pieces ( about
3x3in ). Any ideas? They are thick (1 1/2 in) so lots of
them would be
heavy . They also have sharp edges. I 'd like to use
them with my middle
schoolers.
