There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
The element boron produces a lovely green flame, as long as you avoid contamination with sodium which has a bright yellow flame that tends to overwhelm other colors. Boric acid is a conveniently available boron compound. You can mix it with alcohol and burn it. Very lovely. But of course, be safe. Fire can spread if you do not handle it with care.
The chemical formula for bluestone is copper(II) sulfate {CuSO4}.
Sodium colours the fire bright yellow; Lithium - red; Calcium - dark red; Copper - green, blue-green; Potassium - blue; Magnesium - white
No,because it is not a mineral
Azurite is a deep blue mineral. It is often associated with copper deposits.
The predominant metal in malachite is copper.Related Information:Malachite is an opaque bright blue to bright green copper carbonate hydrate, a semiprecious mineral, that contains the metal copper in combination with carbonate and hydroxide groups. Malachite often contains other metals, but only in small amounts.The chemical formula for malachite is CuCO3.Cu(OH)2.
Azurite is a blue vitreous mineral, a basic copper carbonate.
azurite
Named for its bright blue colour, Azurite is a copper carbonate. It may be an indicator of a worthwhile ore deposit. As a specimen mineral, it should be kept cool and away from light.
Copper is used to make a blue firework!

Copper is a mineral, steam is not.
The anagram is azurite, a blue mineral containing copper.
The correct spelling is "turquoise" (a blue-green mineral, aluminum copper phosphate).
copper sulfate
Cuprosklodowskite is a copper, uranium, silicate mineral, radioactive, the best specimens are bright green acicular masses or carpets from Congo.
