Char Cloth Tins
Posted 25 Jun 2019 in
The Year 5/6 students have been busy in Kaatajin Boodjar creating char cloth tins on the fire in the Wildspace. Char cloth is a swatch of fabric such as linen, cotton or jute, which has been converted through pyrolysis (decomposition brought about by high temperatures) into a slow-burning fuel that has a very low ignition temperature. Char cloth can be ignited by a single spark, that can in turn be used to ignite a tinder bundle to start a fire.
Throughout the process the students recorded important data and times. When the tins stopped smoking the students knew the char cloth was ready for cooling. While the tins were cooling the students spent time in the mud pit.
When the char cloth tins had cooled, the students used a flint and steel to test the char cloth. There was much excitement when the cloth ignited and the students knew they had succeeded.
