this piece has been sitting in my yard FOREVER...it came from a place where gold is abound. It is fairly large. wieghs 46 pounds. I know its quartz but whats the chances of anything of value being inside? what should i be looking for?
Have it tested i am not sure if i seen some thing like it on t-net or not but a photo of a rock like yours was tested for gold i believe it was about 45lbs and had just under 3lbs of gold in it,
Build a fire and put the rock in it then fill up a 10 gallon tub with water and a bag of ice, when the rock gets hot just throw it in the ice water and see what happens.
DO NOT HEAT GALENA, OR ANY SILVER ORE...unless you need a lead fix.
there is a silver mine here in arizona i pick up ore off the tailings...one can place this ore on a burner, and sweat silver and lead out of the rock...a friend, discharged from the navy for lead poisoning....took a piece home...set it on the bburner in the kitchen...several weeks later after he was discharged from the hospitial....he was real mad at me...even though i told him not too.
the fumes will kill you if you are a sensitive, and make you ill and stupid if you are normal.
it is nasty, not recomended method for removing silver from the rock...
