Test Results :: Dark Periwinkle

Effetre Dark Periwinkle (EFF222) is a medium indigo opaque colour that is very soft.

Reducing Dark Periwinkle doesn't alter its colour.

Like it's lighter cousin Periwinkle, Dark Periwinkle can change to a greenish version of itself when silver is added to its surface. Reducing and encasing silver leaf on top of Dark Periwinkle was unexpectedly nice. Because the visible Dark periwinkle between the lacy silver bits fumes a deeper green-blue colour but doesn't do it evenly, there's a lot of pretty variation in the colour.

This colour is an average base for silver glass. My reducing silver glass looks pretty on top of its blueness, with the purplishness of the Dark Periwinkle countering the greenishness of the silver glass very nicely. In the rightmost bead, I got a decent starting strike to my TerraNova2 frit, and I like the contrast of its deep burgundy with the Dark Periwinkle. With a little more work, the colours here probably could have been beautiful :)

Dark Periwinkle is not a very reactive colour. Here, you can see it separating on tp of Copper Green. In the rightmost bead, it rises up in gentle halos around Tuxedo and Copper Green stringer dots and lines. Ivory and Peace separate slightly on top of it.

Here are some beads made with Dark Periwinkle:

Test Results :: Intense Blue

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.

Test Results :: Kryolith White

Lauscha Kryolith White (LAU380) is a stiff, white, opaque glass. I wanted to like this colour, because due to some online marketing of the glass on LE, I had in my head that it would have awesome opacity and would be pretty with silver. It turns out that both of these things are true, which is nice, but there is an absolute vacuum online about this colour's incompatibility. That seems like an important omission.

It doesn't matter that this colour is nice with silver or that it is great with silver glass and beautifully inert when used with other colours. It doesn't matter because anything you make with this White and any other glass colour will probably break within a week of you making it. And this problem doesn't just occur when you encase it. I made some tricolour dot beads with flowers and stripes and various other designs with this colour, Effetre Periwinkle, and CiM Lapis. With my magnifier, I can see tiny little incompatibility cracks wherever this colour meets something else. Interestingly enough, I can't see the cracks when I photograph the beads and view the full-resolution image at 100% zoom, so there's no point in posting them here.

Beads where I used this colour in tiny amounts on the surface of another colour and didn't layer anything on top of it have survived for a couple of months, but I don't know how to feel optimistic about their long-term chances given the magnitude of the problems I observed.

Like with Reichenbach White, this made me sad and disinclined to put a lot of effort into a write-up. But, I made these test beads, so you might as well see them.

Kryolith White does not change colour when you reduce it.

Kryolith White doesn't so much fume yellow with silver as it does turn the silver yellowish on top of it. There's a little yellowing of the base glass, but to a much lesser degree than with Peace, White, or Reichenbach White.

Here, you can see that Kryolith White makes a pretty base for silver glass, but I won't try this again because of the compatibility problem.

Copper Green, Opal Yellow, and Ivory all separate on top of Kryolith White. In spite of it being a stiff colour, on top of Opal Yellow and Ivory, Kryolith White spreads out quite a lot.

There's not much else to say about this. Kryolith White is a tease. It has behaviour and properties that we want and need in a white glass, but then also has the behaviour we can't tolerate in any glass colour that we're going to use in designs that contain more than one colour. I will probably stick to using the least expensive, most reliable opaque white glasses in my work: Effetre White and CiM Peace.
