There is alot of aluminum on many of the guns we decommission, especially assault rifles. And aluminum melts in the forge, so we started making these hearts, casting the liquid aluminum into molds, sort of like pouring candle wax. Each one is about 2 inches wide. They can be passed around as a talking piece, carried in your pocket to strike up conversations, held in your hand to center you in prayer, or placed on your desk to remind you to pray for all the hearts crushed by gun violence. Made from the aluminum from donated guns! (Because we have a limited supply we value them a little higher in price).
