Carbon felt for cosy

[J C]

I have been experimenting with using carbon felt as a pot cosy. The advantage is that you can leave it on the pot while you cook, which should significantly reduce cooking times. It is also quite light and highly insulative. I wonder if anyone else has tried this.

The only problem I can see is getting a connective material that is equally heat resistant. Carbon thread might be the go.

Its been done before. It actually increases boil times.
Its also velcro for dirt,etc.

Carbon felt has its uses..but a pot cozy is not one of them..

Carbon felt is absorbent like cotton. Has tiny loose fibers that play havoc with electrical instruments (keyboards)etc, can short out circuits. Stomach acid probably digests them ;)if you keep the felt in your pot ;)

Carbon felt does not make a good wicking material. Remote fueled stoves that use it retain a lot of fuel at the lower level. The fibers are oriented in a random fashion,not inline vertically.

A cozy would absorb lots of water/food stuff.

Did some experimenting and yes, it does indeed increase boil times, presumably because the walls of the pot are insulated from the heat travelling up the sides.

I still think carbon felt would make a good cosy material, but possibly not any better than neoprene or closed cell foam.

JC,

Yep, San at Batch Stovez mage some upper wraparound cookpot cozys and did a boil test in you tube afew years ago abd found out about the increased boil times..

CF would be OK as a cozy except for stuff getting stuck all over it after a while. Its cool stuff to play with.;)
