Test Results :: Tardis

CiM Tardis (CiM552) is a gorgeous semi-opaque blue glass. In thin layers and if you don't strike it in the flame, it stays wonderfully translucent. My rods of this colour had great workability, not shocking, bubbling, or scumming in the flame.

Here, in the rightmost bead, you can see the Tardis beginning to opacify after giving it an extra blast of heat in a reduction flame. The reduction quality of the flame isn't important for this - repeated heating and cooling of this colour in a neutral flame has the same effect.

Here is Tardis with some other blues for reference. It's pictured with CiM Chalcedony, CiM Poseidon, Effetre Dark Periwinkle, Effetre Laguna, and CiM Electric Avenue. Ideally, I would have included a picture of CiM Atlantis in this picture to show how much bluer Tardis is than Atlantis, but I didn't have any so you'll have to just take my word for it.

CiM Tardis is most similar in colour to CiM Electric Avenue, but is somewhat more muted and a touch deeper in colour than CiM Electric Avenue. It also retains its translucency a little easier/better than Electric Avenue, although it, too, can opacify with repeated heating and cooling.

Silver dissipates on the surface of CiM Tardis. When the silver is reduced and encased, you can see that it has coated the bead in a uniform layer and takes on a snowy, bluish glow.

My reducing silver glass frit turned Tardis green, which was interesting but not at all what I was expecting. Because blue-on-blue is as interesting as a polar bear in a snowstorm, there's not much else to say about that bead.  My striking silver glass got off to a decent striking start on top of Tardis, which means to me that Tardis would be a decent (but not awesome) base for striking silver glass.

Tardis awesomely does not have negative blackening reactions with Ivory. Since many blues and greens do yucky things with Ivory, I always feel lucky when I find one that doesn't.

Copper Green, Opal Yellow, Ivory, and Peace all separate on top of Tardis.  In the rightmost bead, you can see that the Tardis inundates the Opal Yellow dots and stringer lines, making the edges look battered and intermittently pale blue. This happens to a lesser extent with Ivory and Peace.

Here are some other beads with CiM Tardis:
