If you're looking for orange, you could try the veline orange, I found it pretty nice in hue.

For example, arsenic was used in some fireworks long ago to generate a blue color, but manufacturers soon realized that arsenic was too toxic to be used in firecrackers and stopped implementing that clever solution. This is from Google

In past time Paris green use for blue and Paris green contains much arsenic, that why this used for blue. Arsenic trioxide is very similar to Paris green.

No not all time we are right always....we all are learner till we die...If you have such article please share it would benificial regarding boosting our knowledge. But be sure dont experiment it unless you know its hazards. Arsenic compounds are sensitive.

Mr. Zumber u r always right. I read this, in past time arsenic compound use for blue and blast powder may be I wrong. But i try where I read this , I will send u😌

I have seen old formulation diary of our grandpa they were using just for white star. It seems it wont be suited well for blue shade. For flash it is too sensitive. I had samples of both realgar and orphiment 5 years ago but not now.

I got the saltpeter, it's in tiny tiny balls, white as snow, so I imagine this is the good stuff. Only charcoal left I guess, thanks to everyone who helped me!

Arsenic pentoxide (As2O5) and arsenic trioxide, or arsenous acid (As2O3) have been used in pyrotechnics. Both are very toxic but the pentoxide is the worst. There is no reason to even think about using them!

I spoke to a family member that works in the industry and told me he could get some potassium nitrate either later today or after the weekend, so I got that covered. I'm still looking for a metal can to make charcoal out of newspaper though

I think this is what you want....

In old days arsenic compound use for blue shade and flash powder (poisonous and toxic). As Mr. Zumber said in modern pyrotechnics is not common.

You must be talking about orpiment or realgar ( As2S3 or As2S2). Both chemicals have been used historically but not common in modern pyrotechnics. I really dont have heard or read about arsenic oxide use in fireworks.

Your teacher probably means that you should check everything that you have and have done -this is part of the learning process, often more is learned from a failed experiment than from a perfect success.

It is for a school project, I have asked my teacher to give me some clues as to what I've done wrong (after I failed the first time) and she told me to figure it out, so no help there. I don't know what a safety data sheet is, I searched it up and it doesn't really help me

Npk around 13 0 46 is what you want. If in doubt try to look at the safety data sheet.

My barrel is of stainless steel, I'll try 2%

I can't do that because it ruins the color.

Arsenic oxide use anyone in here? If anyone use it please tell me I want to know more details about it.

I have never tried to roll stars with phenolic resin in them. Every time I've used phenolic resin I have either cut or pumped the stars. To be honest, even though I built a small roller, I rarely use it. About the only time I use it is to make color changing stars.

If this is for a school project, perhaps the school can find potassium nitrate from a school laboratory supplier and let you have the required quantity.

Very kind of you to offer but I live in Romania, the shipping cost would probably be more expensive than the saltpeter itself. I will keep looking and asking around for at least 10 grams of this stuff. I will try the newspaper instead of the popsicles, all I need is to find an old paint can. So none of the N-P-K combos I found above work, right?

Also, perhaps the comp is “melting” your roller barrel? Seems like an aggressive solvent ya got going. Or...maybe just 2% PVB

Hmmm..what about dusting the roller barrel with pulverone/fine BP? Be a prime and maybe help with the sticking... like flouring the bowl to mix a dough?

Potassium Oxide? WTH... that label is BS. Guess I don’t know where yer located, but I’d send ya a pound for shipping cost. Hell..I’ll toss in the sulfur too. And try the newspaper.
