Hi everybody I am currently working on rising color tails for cake inserts.I was wondering if anybody had any good bright comps without using magnesium they will not be used for the delay I just wet it with cellulose acetate and smear it on the bottom of the tube all around the visco fuse for a color rising tail I used some star formulas but they werent very bright.

I know you said star mixes aren't very bright but try a blue one with Potassium Chlorate/Copper Sulphate/Sugar. I just put some in a tube yesterday and rammed it, gives a nice blue glow.

Chlorate/Copper Sulfate mixtures are ill-advised at the best of times, but ramming it into a tube is exceedingly dangerous.

I am going to quote a post from Richard H

I'm sorry, did you just say chlorate and sulphur in the same sentence? I think you better stop right there before before bits of you start flying off in different directions all at once.

Well the chlorate/copper sulphate mix is the first post in the Star Formulas section, there is no warning there about mixing the two. I think someone should put one there.

Quote from first post in star formulas thread

Note:Be aware of the properties of potassiumchlorate it MUST not come in contact with sulfer in any way!!!


In any way. That includes sulphur compounds.

Well that's a bit contradictive isn't it? telling you you can use Copper Sulphate/Potassium Chlorate in one sentance and then saying you can't in another. Oh well, looks like i need a new Blue Star formula.

That sulfate formula is from me, I don't use it anymore but I never had any problems with it.
It was and probably is the best blue formula without using chlorinedonors or exotic oxidisers.
I strongly advise not to ram this and other chlorate formulas.

Ok, it is not the sulfate that makes it dangerous. Only elemental sulfur, and perhaps sulfides will sensitize with chlorate. Part of what makes it dangerous is formation of copper chlorate. It can become unstable, expecially if it comes in contact with ammonia. Sulfate and chlorate as ions are compatible.

The other reason it may be bad to ram is that Copper sulfate is acidic. Acid sensitizes chlorate. I think this is the main reason that sulfur is incompatible with chlorate. Acid with chlorate forms chlorine dioxide, and chlorine dioxide hates all organic materials.
