Cuprous Oxychloride
I recently obtained a very very old bottle of 'Cuprous Oxychloride'... I have no idea what the heck it is though.... Maybe it's a synonym for
Hypochlorite or something, but my googling yielded no results. Anyone help me out here?

Did you really try though
Useful for... colouring flames? And um, copper stuff. No real speciality uses though that I know of

I'm guessing it's dicopper chloride trihydroxide, which seems to be referenced as copper oxychloride here and there.
Copper catalyzes the decomposition of hypochlorite, so I wouldn't see a bottle of copper hypochlorite lasting long.

It's a compound, used in pyrotechnics for flame coloring. It is a green powder. It is a basic chloride of copper(II), which has no particularly strong
oxidizing properties (not more so than any copper(II) compound). It has nothing to do with hypochlorite.
The name on the bottle is wrong though. It is not a cuprous compound, it is a cupric compound (copper has oxidation state +2). So, better to call it
cupric oxychloride.

While it is usually green, depending on the preparation and storage conditions it might be a very pale blue as well; tell me if I'm wrong, but it
seems the substance usually called copper oxychloride can be a number of substances, sometimes even a mixture of two.

Copper Oxychloride: CuCl2.3Cu(OH)2 MW 427 g/mol
Dicopper chloride trihydroxide: Cu2(OH)3Cl MW 214 g/mol
Essentially different proportions of copper to chlorine and Hydroxide. So not really the same.
‘Calcination… is such a Separation of Bodies by Fire, as makes ‘em easily reducible into Powder; and for that reason ‘tis call’d by some
Chymical Pulverization.’ (John Friend, Chymical Lectures London, 1712)
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. (William Penn 1644-1718)
