You will need nitrocellulose. Unless you want to dabble in high-explosives, or you have access to smokeless propellant, your only way of doing this will be dissolving ping pong balls in Acetone.

You should be able to find a method with some quick searching.

I also managed to source NC lacquer here

It's a bit of a bargain. ?12 for a big aerosol of NC lacquer in Acetone, and that includes delivery to the UK! I've yet to use it though - Any idea how I can test the quality?

Wow. Very interesting. I'd like to try using the aerosol for priming stars. Should make the process much easier.

Perhaps you could spray some on a clean surface, let the Acetone evaporate, then see how the residue burns? Not sure how this will relate to quality, but when dried, my NC lac burns like "slow" cotton (slower burning flash cotton used for handheld smoke effects.

OK - I've sprayed some on a bit of newspaper. Just waiting for the peardrops to go away [acetone to evaporate]

Update! Hmmm - Initial reaction not promising. I cannot see any difference between NC coated newspaper burning and normal newspaper burning. I'll layer the stuff a bit thicker and let you know.

Well it certainly waterproofs well. Strips of the the newspaper I sprayed it onto can be set alight even after putting them under a running tap.

When you say it burns like "slow" cotton, do you mean slow guncotton?

Spray a decent coat of the laquer onto some glass, then scrape the dry film of NC off.

Tins NC laquer can be bought at hobby/model shops. It is used as "dope" to tighten and varnish tissue paper covings on model aeroplanes. A shop selling this will probably also sell tissue paper too - proper stuff, not kitchen roll.

Beware of "non flammable cellulose dope." It is cellulose acetate solution, not the same as cellusose nitrate. "Irvine Cellulose Dope" is one brand that works well.
