About Posting a Comment

Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.

Author Name is a required field.

Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.

Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.

You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!

Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Sulfur and Charcoal are the two easiest to aquire chemicals. Sulfur can be found at reasonable purity in hardware stores as a garden product, some supermarkets even carry it, as do some chemists.

Charcoal can also be found in supermarkets and hardware stores as BBQ fuel. Of course the quality for pyrotechnic uses varies, and brickettes are basically useless, but many of the true lumpwood charcoals are usable. They will generally be pine or similar cheap timbers, which make good sparks by not excellent propellant grade BP. You can always pyrolyse your own charcoal and control the timber type and the temperature it was pyrolysed at to optimise it for your purposes.

Sounds completely insane to me. Chlorate + Sulfur is just asking for an accident. Please don't use this composition!

Just to add another recipe, I was playing with quite long ago. Used a circa 12-14 gauge cotton

string coated with a finely powdered stoichiometric mixture of potassium chlorate, sulfur and pine rosin, stirred in chloroform based PVC glue. Made it to be as consistent as sour cream. Result: moderately fast burning ( rosin makes it go faster ), moisture proof, burns even submerged, sturdy )

Not really no. It got a bit beaten up in transport, and I had access to commercial fuse around the same time. Still have it, just haven't played with it much.

I was thinking of using it with different compositions, like colour and propellant ones to make flying fish, etc. Always wanted to try Senko Hanabi in it as well, but I suspect there would be too much string and not enough comp for that to work well.

Did anything ever become of that visco machine?
