Test Results :: Carnelian Opalino

Effetre Carnelian Opalino is such a beautiful colour of pink. I find it an easy glass to use, without significant boiling or shocking issues the way people fear with the Opalino colours. Each batch of Carnelian seems to be a bit different, with the most recent batch being beautifully rich in colour.

It's also among a small number of deep pinks that are not antagonistic towards Ivory, because colours like Opal Raspberry, Rubino Oro, Cranberry, and Sedona turn Ivory into a black mess. It's nice that there are a few pinks out there that can be used with Ivory without creating that problem.

Reducing has no real effect on the colour of Carnelian Opalino, but here when I reduced the bead, reintroducing it to the heat resulted in the colour striking.  Carnelian is a striking pink, and the more times you heat and cool it, the pinker it gets.

In these beads you can see that using silver with Carnelian turns it a bit orange, which is consistent with how I am accustomed to pinks behaving when silver is added. Reducing and encasing the silver made most of the orange go away.

Carnelian is a nice base for silver glass. My reducing silver glass pops on top of it colourwise, mostly because of the good contrast between the yellowed pink and the blue frit. In the rightmost bead, you can see that colour started to bloom early in my TerraNova2 frit, which is a good sign that this is a decent base colour for striking silver glass.

Copper Green separates on top of Carnelian, and when Carnelian is used on top of Copper Green, you can see light lines around the Carnelian as well as a fracturing of the Copper Green into little beads of dark turquoise. Neat.

Opal Yellow also separates on top of Carnelian, and on top of Opal Yellow, Carnelian looks a bit orange. I think this is because it is semi-opaque, and it's the result of the yellow peeking through the pinkness.

There are no real reactions to speak of with Carnelian and Tuxedo, Ivory, or Peace.

Here are some beads made with Carnelian.

Test Results :: Elphaba

CiM Elphaba is a beautiful spring green.  For the longest time I've shied away from brighter colours, but I've burst out of that self-imposed prison this year, and I'm hooked on this one. After some very minor encounters with the bright Effetre greens (Nile Green, Pea Green) I approached this colour thinking that it would be more aggressive with other colours, and streakier. I was pleasantly surprised!

Elphaba is a surprisingly soft colour. I'd rate its viscosity maybe a 1 or 2 on the scale where 0 is Effetre White and 10 is Effetre Black.

Here, you can see that reducing Elphaba in the bead on the right had no effect on the colour of it.

Silver causes a little bit of brown discolouration when it's used on top of Elphaba.

I don't really understand the things that happened when I reduced and encased the silver, because the brownness seems to have diminished, and really organized itself in a vertical line in the rightmost bead. Possibly that was a join line in my encasing, and so maybe it was all looking for somewhere to go and there was some space there before it melted in?  I just don't know, but it's one of those things that make me go "hmmm".

I'm not sure what to say here except that Elphaba doesn't really make a pretty or particularly effective base for silver glass.

Tuxedo makes Elphaba separate, and so you can see in both beads how wherever the two touch, the Elphaba develops a line. In the bead on the left, the result looks like a green outline to the tuxedo stringerwork that is faintly outlined in black. In the bead on the right, you can see a faint black line through the Elphaba stringer lines and faint black dots in the centre of the Elphaba dots.

Copper Green, Opal Yellow, and Ivory all spread quite a lot on top of Elphaba, and the Copper Green looks really Turquoise when it's used with Elphaba and even blushes a bit pink in places, but there's no trace of the dark patina that often develops on it.  Also, around the Copper Green stringer lines there's almost a fissure-like outline and you can see in the rightmost bead that the Elphaba has separated on top of the Copper Green.

Opal Yellow strikes odd pinkish grey in blotches when it's used on top of Elphaba, and around Elphaba dots and stringer lines. Peace goes a little weird in the same way on top of Elphaba, but so mildly that it's not very noticeable.

There are no real reactions of note with Ivory.

Here are some beads made with Elphaba. This colour has stolen my heart :)

Test Results :: Sky Blue Opalino

Effetre Sky Blue Opalino is a lovely pale blue semi-opaque colour. I used rods from two separate batches (bought eight years apart) and there was no variation to speak of between the two which was nice. It has a unique reaction profile, and I was able to do some pretty fun things with it. And since the Opalino colours are widely feared and reviled, it's not very expensive.  Win!

When I was using this colour on my 5L oxycon, I got a lot of sooting no matter how cool I tried to work and how neutral I tried to keep my flame. It was pretty frustrating. But, at the beginning of September I got a new 10L oxygen concentrator, and it has been a very happy experience discovering that not all of my problems are my own fault!

I don't find this colour particularly shocky, and I didn't have any trouble with boiling it, either.

Here, you can see that in the bead I reduced, some of the brightness has been stolen from the colour. There are two things at work here - the first is that repeatedly striking semi-opaque colours pretty much universally (with the exception of the pink opalinos, and ghee and possibly a few others that are striking colours) opacifies them and lightens the colour. But I do believe that reducing it has changed the colour slightly as well, making it tend a little purpler than in the unreduced beads.

Here's something that I did not expect. This is the first blue that I've tested that turns brown when it's used with silver. It did it both in the bead where the silver is on top of the colour, and the bead where the silver is reduced and encased on top of the colour, although reducing and encasing it resulted in a much lighter brown.

Silver also behaves a bit differently on top of Sky Blue Opalino than it does on   If we look back at one of my early tests of Vetrofond Pajama Blue, which is the colour closest to this one that I've tested (I think - there are really a lot of tests up here at this point), we see that the reactions are quite different. With Pajama Blue, the silver turned brown. In these beads, the colour change is in the Sky Blue Opalino.

In the bead on the left, you can see that the silver glass reduction frit has discoloured the base bead giving it a really interesting antiqued look.  Also, the reduction has deadened the colour of the Sky Blue Opalino, making it contrast better with the colours of the frit.  

In the rightmost bead, although I didn't get the colour very uniformly, I got some gorgeous colours from the TerraNova2 frit towards the bottom edge of the bead.  This tells me that this is a pretty friendly base colour for striking silver glass.

On top of Sky Blue Opalino, Tuxedo looks blue-ish.

Copper Green separates when it's used with Sky Blue Opalino, and when it's used on top, it gets a pinkish grey outline to its dots and stringer lines.

Using Sky Blue Opalino on top of Opal Yellow seems to have helped it to strike a pinkish colour. Opal Yellow and Peace both separate slightly on top of Sky Blue Opalino.

Sky Blue Opalino reacts with Ivory, and you can see that the Sky Blue stringerwork in the leftmost bead has turned a brownish colour, and the Ivory stringer lines and dots are ringed with a faint dark line in the bead on the right.

Here is a very small sample of the fun I am having with Sky Blue Opalino.
