Things You'll Need:
- Large piece of ice
- Knife
- Tinder
-
Step 1
Cut a small block of ice, and use the knife to trim the ice into a circular shape. You can also use a rough stone or a piece of cement to grind the edge of the ice. The glass should be in a lens shape, with the middle of the glass thicker than the edges.
-
Step 2
Use the warmth of your hands or a damp cloth to finish shaping the ice, and to melt and smooth the surface.
-
Step 3
Make a small pile of dry tinder where you want your fire to be located.
-
Step 4
Hold the ice in a perpendicular direction to the sun, and adjust it to direct a bright ray of light directly onto the tinder, but be careful not to let water drip on the tinder. The tinder will eventually begin to smoke, and then ignite. Add more tinder, if necessary, followed by small kindling.
