Glass Testing: CiM 551 Prussian Blue & 442 Prairie Grass Ltd. Runs

 New colors today! I have one brand new color in this post and one that was in the batch from last year that I hadn't had a chance to test until now.

First off, we have the new color, called Prussian Blue. This pretty deep opaque color is a kind of midnight blue in the rod, but because it has a lot of silver in it, Prussian Blue is reactive.  When left as a base, uncovered, Prussian Blue is very dark blue with some streaks of greyish green. This is a lot like Class M Planet, which does the same thing but is lighter in tone.

When you encase or layer Prussian Blue, the blue tones become brighter and the greens all but disappear. This color makes an excellent layering glass if you want some rich midnight, navy or cobalt blues.

Because this is a silver glass, it's not as smooth in consistency (it's slightly bumpy when pulled into stringer), and is slightly stiff, but seems to be able to take a good amount of heat. When left plain, Prussian Blue has lots of striations and streaks - some blue, some grey-green. But that goes away when you encase it.

I had no shocking issues with this color, and it didn't bleed or spread when encased or layered. Using it with a medium or light transparent blue will give you a gorgeous rich midnight blue.

Next we have Prairie Grass, a light opaque spring green that came out late last year. This pretty shade is really close to Elphaba - just a little bit lighter and a little bit more yellow (but not much!). I would say that both these colors can be used as a substitute for each-other.

Prairie Grass is really buttery and nice to work with. It does get striations when left as a base, and can bleed a tiny bit when encased, but not nearly as much as the Effetre greens do. It doesn't seem to spread much at all when layered. This color didn't shock when heated, and had no pitting or boiling issues.

Like most opaque greens, Prairie Grass lightens up a lot when encased in clear, and goes a little more yellowish. I loved using this color with just a bit of Effetre Light Emerald - makes a cheerful spring green.

The beads below were made with Prussian Blue and Prairie Grass, paired with Effetre Light Emerald and Effetre Light Blue.
