I have been experimenting with making char cloth for a few weeks, when time permits. Today I got it right .
I tried a large tin and a smaller tin for comparison. The large tin was one a mug came in at Christmas, the smaller one was a tin which used to have air rifle pellets in. Both tins had holes punched in the top with a nail.
The raw material I chose was 100% cotton car polishing cloth from Halfords (no connection etc.). It has a nice open weave and you get loads for about £4.00.
I used my group buy collapsable fire box with the grill in place. After getting a fire going and nice and hot I put the air gun pellet tin on and it began to smoke from the hole almost instantly. I left it in place until the smoke has cleared and for a while after. Then I took it off and repeated the process with the large tin. Due to it's size the large tin seemed to take a lot longer.
The results were better from the smaller tin, though the larger tin produced good results. The charring was less uniform, some of the cotton remained brown suggesting it could do with a little more heat.
Both sets of black charred cotton caught a sparks easily from a traditional flint and steel and blew easily into a coal.
For the first effort (which was unsuccessful) I used a pair of old pants, as they had lycra in them they wouldn't catch a spark. This taught me that the raw material is very important. I understand that as well as polishing cloth 100% cotton denim jeans and tea towelswork well.
All in all I have had a very rewarding afternoon!
