Fire glass produces more heat than real wood and is environmentally friendly. There is no smoke, it’s odorless and doesn’t produce ash. Stay toasty warm without cutting down trees and the specially formulated glass crystals give off no toxic deposit.
This is called a Swedish flame. Make your cuts like you're cutting cake, leave about 6 inches at the base, throw about a cap full of fuel oil in it. It burns up to two to three hours Can use olive oil instead of fuel oil :-) Any oil will burn!
