the paper tube burns away, ive tried, it has to be metal. ive tested
several of these tubes and they all burned fine. DH Barr that gives me an
idea, i saw that we have some glass insulation in our ceiling, mabe i could
wrap it witht hat and give it a coat of plaster of paris on the outside.

Why does the casing need to be copper? I've seen devices like this go
into thermal runaway; basically the copper conducts heat not just outward
but also upward along the length of the device. It can get hot enough to
ignite material that isn't exposed to the flame front, and you get a big
E. Adding thermal insulation would only exacerbate this problem. Can't
you use, say, a paper tube? That would solve both problems - conduction of
heat to the smoke formula, and conduction to the rocket.

Hi, i need some help. Im the rocket i am currently working on, i want to
put a long duration burn smoke device into the body of the rocket and
manually light it just before take off so that should something go wrong
and i lose sight of the rocket, i can find it by the copious amounts of
smoke it will be giving off. The smoke device is a 15cm long copper pipe
filled with the ledgendary smoke mix which burns for about 2 minutes. The
problem is that this tube gets extremely hot and will set fire to the
rocket uf it touches the body, to remedy this i will need something that
can be shaped around the tube, wont catch fire or be damaged by high heat
and is a good insulator. It also needs to be light weight. Ive comr to you
guys to help me name this material-x. Ive included a diagram of what the
set up would look like. Any help would be greatly appreciated.
