Cuprous oxide prodution.

[kleberrios]

Hi guys. Anyone ever make blue fireworks comps with these things? cuprous oxide, red copper oxide, copper I oxide. I am manufacturing this industrially, and it looks very good to me. Does anyone have any good or bad comments about its use in pyrotechnics? The only incompatibility of the product is its mixture with ammoniacal salts. Substitute black copper oxide for it in blue formulations and it worked perfectly. All that remains is to try in Kracling's formulations.

Sorry, I've only used copper II oxide (black copper oxide) for my blues. BTW, cuprous oxide and copper I oxide (or red copper oxide) are the same thing. cuprous= copper I and cupric =copper II. Additionally, ferrous= iron II and ferric= iron III. The terms cupric, cuprous, ferrous and ferric are considered "old school" and not really used much anymore. Chemistry has gone through a LOT of names for the same chemical over the years. Some examples of old "common names" for chemicals: muriatic acid (hydrochloric acid), muriate of potash (potassium chloride), niter, salt peter (potassium nitrate). the list goes on... but it can very easily get confusing. I had to get accustomed to these various names when I worked in the laboratory at a plating company many years ago. My job included doing quantitative analysis of the various metal treating baths and when I would write out work orders for chemical additions, I had to use the common names for the chemicals or else the maintenance men wouldn't know what I was talking about.

It is supposed to work just as CuO.
t is not commonly used in the industry because it contains more copper making it more expensive, while the black cheaper variety gives the same effect for less money.

But being easily decomposed to copper and CuO I would think it should make (probably) better blues with AP and possibly be a candidate for blue strobes.

Please do keep us updated on the crackle comp.

To me looks Better then CuO, probably because add more Copper, so Blue Is much intense.
