etkallagh asked:
when working from the top downward, what do i do or use to split the collumns of jasper along its naturally occuring fracture? Jasper is quite hard and most metal picks, chisels, and hammers are NOT effective.I have heard there is a substance that is inserted into holes that are drilled into the rock that forces it apart by slow expansion..If so, what is it and can i aquire it? If this isnt possible,what is the next most efficient and logical method?
