Test Results :: Tahitian Pearl


Tahitian Pearl (CiM827) is a dark greyish purple that gets shiny in the flame while you're working it. As you'll see, I went into my relationship with Tahitian Pearl expecting it to be similar to Adamantium, but ultimately found it quite a bit more like Effetre Dark Silver Plum, only with more interesting variation in surface texture.


With repeated heating and cooling, the surface of Tahitian Pearl gets all shiny, wrinkly, and uneven. I was alarmed by this when I was making these two beads together on the same mandrel. Then, I reduced the bead on the right and thought that all of the neat surface finish had gone away and was alarmed by that.

And then I took the beads out of the kiln the next morning. It turns out, the wrinkly, textured shiny finish of the unreduced Tahitian Pearl is awesome, and reducing does not take away the surface finish, it just smooths it out. Also awesome.


At first, I thought Tahitian Pearl was like a shiny version of Adamantium. Then, I made this bead and realized that Tahitian Pearl is purple while Adamantium is not, and that silly first impression of mine popped like a soap bubble.


On top of Tahitian Pearl, silver disappears. When the silver is reduced and encased on top of Tahitian Pearl, it turns yellow. Ignore the peach and pink you see on the leftmost bead. This colour doesn't turn silver leaf pink the way Dark Silver Plum does. What you're seeing there is my hand and my T-Shirt in the shiny finish. Reflective!


Tahitian Pearl makes an interesting base colour for silver glass. I got neat colours and reactions from both frit treatments here without much effort.


Here, you can see that Tahitian Pearl separates on top of Tuxedo, but apart from that it seems not to be very reactive with other colours.

This bead was made with Tahitian Pearl and Raku Mottleshards.

Test Results :: Amethyst


Amethyst (CiM629) is a light purple transparent. It's pretty with silver, and makes a deeper pink when layered over a light pink like Desert Pink. It's not very reactive.


I always struggle with the lightest CiM transparent colours. I was a bit surprised to find that I had different problems with this one than I have had in the past with colours like Larkspur and Count von Count, because I didn't experience any bubbling with this one.

I did get strange 'snail trails' of pale semi-opacity through this colour while I was working it, though. This is similar to the challenges I had with CiM Experimental, CiM's newest Clear. And that makes sense, since Clear is probably how this colour starts out before the purpliness is added to it.


Silver loves being on top of Amethyst, crusting up in interesting ways on its surface. Amethyst does not discolour silver when you encase with it, and a layer of silver leaf reduced and encased on top of Amethyst turns an ethereal silvery blue.


Silver Glass on top of Amethyst is pretty.


Amethyst lightens up considerably when used in thin layers. It is not very reactive, so there's not much to say about these beads.

Here's a long bicone that includes some Amethyst.

Test Results :: Green Cave


Effetre Green Cave (EFF856) is a gorgeous, medium-dark green glass that some people seem to have been able to make turn blue with selective reheating. I haven't experimented much with that, but it's clear that nothing I did while making these test beads evoked blueness from it.


Reducing Green Cave seemed to make it a little darker. It's not very clear if this was because of the reduction flame or if this is a striking colour - I'd need to experiment with it a bit more before I could be sure.


Here are, side by side, the two different tonalities I have of Green Cave. I prefer the one on the left, but honestly I love both of them. It's so rare to have a dark green that doesn't do nasty things to Ivory, and I am going to enjoy every last crumb of it.


Green Cave reacts like Ivory when silver is added to it, which makes me wonder what silvered Green Cave stringer would be like. In the bead on the left you can see how the silver crusted up and looks misty and blue in places. When the silver is reduced and encased, it's less attractive, showing patches of brownish green and losing any lustre it had before the reduction/encasement.


Like Ivory, Green Cave makes a really interesting base colour for silver glass. My reduction frit got all kinds of interesting borders and fading, and I got dark outlines around my TerraNova2 frit and lots of initial, interesting colour. Like Ivory, Green Cave is very soft glass and the TerraNova2 frit migrated towards the centre of the bead as I was heating and shaping it.


Tuxedo makes Green Cave separate into lighter and darker versions of itself, both  when used on top of and underneath it.

Copper Green separates on top of Green Cave and develops a dark outline. When the Green Cave is on top of Copper Green, it also separates and gets a dark outline.

Opal Yellow gets a dark border with Green Cave, but only when the Opal Yellow is on top.

Ivory spreads out on top of Green Cave and the Green Cave separates underneath it.On top of Ivory, Green Cave separates but doesn't spread at all. If anything, the Green Cave lines look narrower on top of Ivory than on top of the other colours I tested it with.

Here are some other beads that include Green Cave.
