Valpolicella Ripasso is a form of Valpolicella Superiore made with partially dried grape skins that have been left over from fermentation of Amarone or recioto. Winemaking in the region has existed since at least the time of the ancient Greeks.
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy.
Typical flame test colors are the same as coloring compounds for fireworks. Calcium gives a Red-Orange. Boron gives bright Green. Barium is Yellow-Green. Copper (II) as a halide gives Bluish-Green. Other Copper (II) salts give a Emerald Green. Molybdenum gives a Yellowish Green. Phosphorus gives a Pale Bluish Green. Lead, Tellutium and Antimony are Pale Green.
