CiM Tester Feedback

  • Cotswold Blue is a unique addition to the 104 glass color palette.
Cotswold Blue melted with no issues or fussing and is a great addition to the 104 palette! – Trudi Doherty
As for the glass palette - Cotswold Blue seems to be relatively unique - it's darker than Quetzal, bluer than Sherwood or Elf, more muted and slightly lighter than Mermaid. Read more at Kandice's blog. – Kandice Seeber
I can't really decide if this is a green or a blue. Either way, green or blue, it is unique to the 104 palette. – Caroline Davis
I believe that CiM Cotswold is a colour that we have not seen in the 104 glass colour palette before. Oh, there are colours that might be a little darker or lighter, there is a translucent colour that is similar - but this hue of a rich, opaque greenish turquoise seems to me to be new.

"Copper Green, Ivory, and Opal Yellow all separate on top of Cotswold Blue. Cotswold Blue is such a streaky colour that it separates on top of everything. The only real reactions of note here were:
-Ivory and Cotswold Blue form a mutual dark line reaction
-The edges where Peace and Cotswold Blue meet get sort of fuzzy and translucent. You can see this in both beads." Read more at Melanie's blog.

"Glass Figa Charms!!!! I’ve wanted to make these for years. The 'turquoise' one is made from CiM glass’s color called 'Cotswold Blue' which is one of the most realistic turquoise colors I’ve ever worked with, it doesn’t reduce and keeps a beautiful clean creamy finish."

"I was concerned that other beadmakers had reported striations in the glass once it was worked, but I saw only minimal striations so I suggest working it in a cooler flame to keep these under control." Read more at Darlene's blog.

"I said there was something interesting going on with Cotswold. I said that it bubbled - big bubbles rising through it, not the fireworks sparkle like turquoise, and not the big bubbles of not sufficiently dried bead release. Just bubbles forming and rising to the surface and popping. And check this out - this greenish [by comparison] smear of Cotswold on the turquoise melange of background - did some interesting things."

"I can't really decide if this is a green or a blue. In the picture it is more green than Quetzal which is more green than Effetre Dark Sky. Either way, green or blue, it is unique to the 104 palette. The beginning of this rod I had no problem with shocking but towards the end of the rod I did have some shocking which is unusual."

"Cotswold Blue is another stunner of a colour, a delicious teal shade that sits in that special place exactly in the middle between blue and green. This glass gives a lot of striations - similar to those you see with CiM Mermaid and Quetzal. Cotswold Blue is not reactive with silver leaf at all. As you can see in this last picture, all that is left behind in the areas where silver leaf has been vapourised are the smallest droplets of silver and no colour change to the glass itself at all."

"While it does melt nicely without too much shocking, I got a lot of striations with this color. It separates a lot, even when encased. The larger the bead, the more striations under the encasing I saw. Left un-encased, there were lots of striation marks and lines as well. This can have design potential for some, but for me it's not as desirable. . . Cotswold also didn't bleed or spread a lot, which was nice. I had no problems encasing it. This means it will likely be a really nice color to use underneath bright transparent teal shades to deepen the color." Read more at Kandice's blog.

"Cotswold is a muted turquoise. The opaque glass reminds me of Quetzal, but with heavy gray undertones. The glass feathered nicely when paired with fine silver foil and a Lapis Ivory. No shocking or bubbling occurred during testing." Read more at Heather's blog.

"Cotswold Blue was very shocky. Now I am not a patient torcher [like straight into the flame with little warmup time for the rod]. So that might have been part of the problem. Once I got it going it was fine." Front strand shown here was etched.
Amy Hall
"Described by CiM as an opaque teal, my initial thought was that it was a bluer version of Celadon. As you can see it sits nicely with Duck Egg and Dirty Martini. When I added a thin strip of Dark Multicolour, I could see straight away how much this spread across the bead, and it has lighter green rings on each side. Thinking that it may have some spreading properties, I made a bead with Peace polkas but they didn't have the tell tale sinking dots. One to explore further…"

"Cotswold Blue melted smoothly with no shockiness or bubbles, and is reactive. It is a new color to the 104 palette. It is similar to Mermaid, but I did not get as many striations in the Cotswold Blue as with the Mermaid." From left to right: Cotswold Blue, Quetzal, Smurfy, Mermaid.
