[Green_as_my_powder]

O.K. I've been looking. I found the Kosanke formula for green in an old post on this forum, but not the others. Could you supply the rest? Or at least a hint where to look next? To be honest, I'd rather be building stuff than net searches...

Any help appreciated.

I don't remember where I found them- but didn't Skylighter buy the rights to some of their comps? Looking there might help.

I have a HyperSnap of several pages in table form. Unfortunately, the forum doesn't allow uploading images straight from a computer- it requires a URL.

Rewriting it isn't likely, there's 21 diff. chems, 12 star comps, 2 primes and notes.

Thanks for the link! I had found the book there, but got tired of paging through and never made it to the formula.

It's interesting, because the formula I did find for Green (credited to Kosanke) was different. It included MgAl and atomized Al.

Next question: The Kosanke blue formula calls for paris green, which I don't have, can't find, and heard it was fairly toxic. Any other blue formula that I could mix with the other Kosanke formulas? Any source for paris green (preferably in the US)?

Thanks again (and again) for all the help!

I've never used hyperSnap, but you could probably print to a Acrobat PDF file, or do screen captures and save as JPG files. Anything is better than typing it out!

It probably took longer to ask for the spoon-fed answers than to have looked it up yourself, if you found that book to review (it is less than 30 pages...). I think I alluded to this earlier- IMO, you're just not trying hard enough!

The formula you found was most likely the star formula- it does contain 4% magnalium and 9% atomized Al. The formulas from Creepin_pyro's link (thanks for that, C_p!) are for lances.

You are probably right. I should have looked more. In my own lame defense, I live in the middle of nowhere (good for fireworks, bad for internet) and all I have is dial-up internet which never connects at full speed because the phone lines are so bad. The book site took quite a while to load each page...whine...whine...whine.

I'm sorry to repeat myself, but I'm still stuck...

The Kosanke blue formula calls for paris green, which I don't have, can't find, and heard it was fairly toxic. Any other blue formula that I could mix with the other Kosanke formulas? Any source for paris green (preferably in the US)?

What's worse, (or really neat...depending on your viewpoint) is that my eldest daughter is considering doing a science fair project on combining different colors of light, and comparing the results to combining different colors of paint (don't laugh...she is only 10 y.o.). So I'm hoping to find a solution to the paris green problem. I'll probably have to use the Veline formulas (which I've heard produce somewhat pale colors) if a substitue can't be found.

Thanks again (and again) for all the help!

You didn't read any of the words in that book, did you?

You're going to have a hell of a time finding paris green. You could probably substitute another copper salt, such as Copper oxychloride for it though.

There are some simple, compatable formulas in Hardt on page 118.

Any source for paris green (preferably in the US)?

This is the ONLY supplier I've found recently- and he's currently out. Check the site occasionally, he's looking to restock.

I should have bought more when I could have, it's going pretty fast since I realized how nice the blues are that it makes.

[Green_as_my_powder]

Thanks for the link, but I didn't see any paris green listed. Perhaps they have stopped selling it as well...

[Potassium chlorate]

I would also be very interested for a source of Paris Green but in Europe. The colour is most superior.

On topic: cryolite is very good for yellow, and it's non-hygroscopic. Ceramic suppliers have it, and the quality is quite alright for lances and Bengals.

Part of me wonders if the Paris Green color is really that much better, or if it is just part of the "back in my day, things were better" syndrome. Looking back on my shells, I am sure my memories are doctored to make them seem better than they really were. Regardless, I still plan to make some PG, and do a side by side test. I know another person who has done this, who has quite a bit of experience. Oddly enough, the perchlorate compositions came out the best in his tests. I have some HCB too, which I hear the secret ingredient to the great PG blues of the past, so we shall see. HCB comps were one thing he did not test.

My thoughts exactly on this item

[Potassium chlorate]

I have only seen it on Youtube (I might have seen it IRL too, of course, but not to my knowledge), and it looks much deeper than any other blue. And it's pretty dark blue, not blueish-white, blueish-violet or blueish-indigo.
