Healthstone works by using only the heat from the a triple flame torch. Easily vaporize your concentrates on the go. Keep the end of the torch flame approx. 1-2 inches away from the stone. The heat will transfer over and initially melts your concentrate into the stone as you inhale and taste the terpenes, as the stone continues to heat up further, you will get increased vapor, and be in for an enjoyable sesh.
See below, the torch is just outside the frame, never touches the stone.
