Look at my feedback to see what others are saying about my fire piston If you have any questions Just send me a message Thank you for looking Fire Piston Consists of a hollow cylinder ranging in length from about 3 to 6 inches sealed at one end and open at the other. A piston with an airtight circular seal ( oring) is fitted into the cylinder The compression of the air when the piston is quickly rammed into the cylinder causes the interior the temperature to rise sharply to 500°F This is hot enough for the char cloth in the piston face to ignite. The piston is then quickly withdrawn before the now-burning tinder depletes the available oxygen inside the cylinder. The smoldering char cloth can then be removed from the face of the piston and transferred to a larger nest of fine kindling material, such as Kapok Jute Twine, Paper Towel, birch shavings, etc. The ember is then fanned or blown upon vigorously to create a flame, at which time various stages of larger kindling can be added until built into a proper fire This type of fire piston is not for EVERYONE some users find it hard to get a ember until they get the technique down...I always suggest my Hickory Fire Piston Found***Click Here***...Simply because it has a wood case and gives more cushion to your hands when you ram the rod into the cylinder..
