Raven by Glass Alchemy
Raven is GA's densest black. This color can be pulled down to a fine stringer and it still maintains its color saturation. For a saturated black, this is a surprisingly easy color to melt and shape. It does contain chrome, so be sure to take this into consideration. If you want a chrome free black, check out Eclipse, 9977. Eclipse is less saturated than Raven, but is a highly workable chrome free black.
Working Tip: Work in neutral flame. If you flash heat in a reducing flame as you finish the project you can produce a look similar to the sheen of a raven's wing.
