Effetre Intense Blue is a gorgeous dark blue transparent. It has a lot of punch when it is used in thick layers, but thins out colour-wise considerably when used thinly on top of other colours. That said, it is a lot bluer on top of white than most of the other transparent 104 blues because it starts out so much darker.
Here you can see how beautifully dark and rich this blue is. It doesn't change when you reduce it.
Intense Blue and Silver don't have much of a reaction. In the bead on the left, you can see that silver leaf formed a crust on top of Intense Blue, and then you can see in the bead on the right that when that 'crust' is reduced and encased, it mellows out into a greyish blue coating.
Neither of these beads show much of interest with regard to silver glass, although Intense Blue makes a pretty, inoffensive base colour for reducing silver glass frit.
Intense Blue lightens up considerably when you use it in thin layers over other colours, but still maintains its essential blueness. You really need a blue this intense if you are going to try to use it over white to make flower petals. But if you're making blue flowers, you'll probably want to use a light blue or lavender base glass with this colour to get deeper colours.
Intense Blue is not very reactive, and apart from some separation in Copper Green when it is used over top of this colour (and even fainter separation in Opal Yellow and Ivory), there is not much to report here.
I didn't make much with this colour yet, but here's a simple little earring pair.
