DO NOT until you check Tenney or some other reliable source. I could be
wrong, but I think that's Cheddite.

This gave me an idea. Would it be possible to create a wax and KNO3
mixture? I understand the ratio would change compared to the standard sugar
ratio but would this work? It would require a lower to melt and the the
risk of decomposing the fuel is so small that it would likely never happen.
I know that parrafin was has been used in hybrids so why not start there
and just add an oxidizer into that. With wax it should be easier to cast
grains with cores since wax in and of itself will act as a mold release.
This could also help in casting not so simple cores. I'm especially
interested in this idea because I want to try and cast some grains with an
x shaped core to achieve a different burn profile. I'm currently at school
so I can't look much into the details but I will once I get home.

Ive attached the recipe below. I made a small tube with an ID of 1.3cm
and 5.5 cm long filled with this smoke mix and it produced a steady and
thick smoke for something like 2 minutes! It does take a moment to ignite
so it would need to be primed by making a small cavity with a pencil or
something of that size and putting r-candy or rammed powder fuel into it to
get it going. To make it you just need to grind up the dry ingredients in a
coffee grinder, mix them, melt the wax in a small pot or even just a soup
can and add the powder, mixing it thoroughly. Make sure to work with it
when it's warm and soft, it gets really hard and lumpy when it's cold.
