Belladonna - you may remember - is a new, boutique line of 104 glass in some specialized colours. This is Royal Purple, as a frit.
Royal Purple is a blue purple, more like Tanzanite than Amethyst.
This is a base of clear, Royal Purple frit, melted in.
This is a base of clear, with Royal Purple, and reduced. Reduction didn't seem to affect it. It did seem to get darker - more like it was striking, but maybe that was just me getting more frit on the bead.
Nice colour - I personally prefer the purple that don't have a lot of red in them.
