The Mineral Identification Key Fusibility is a measure of how much heat it takes to melt a mineral into a globule, or at least to melt the sharp edge of a sharp splinter and make it round over. Quite a few minerals are easily fusible in the flame of a candle or typical cigarette lighter: A small, sharp, splinter held in the flame either melts into a globule or its edges round over easily.
