My batch of CiM Glacier is so old, that some of the rods have the original tag name for it; “Blue Slate”. Although CiM went on to produce a different glass with a similar name (Blue Steel), which is an altogether different colour. Glacier is a solid cool pastel blue, that is soft and buttery to melt in the flame. I’ve never had it ping or crack even without pre-warming the end of a rod. Its a very forgiving glass as it is hard to burn and holds heat deep in its core, which makes it a good base for finicky designs.
I’ll confess that I’ve only recently fallen in love with Glacier, I thought it was such a “blah” colour for a long time. I didn’t think how this particular shade of non reactive, non streaky, just very plain blue was anything special. I was so very wrong. I’ve gone from hardly using Glacier to spending the last six months constantly using it.
Glacier completely loses any of it’s streakiness (not that my batches have much streakiness to them at all) when heated over a long period of time. It’s a very solid soft pastel blue colour that etches to perfection. (Yeah, I am in love with this glass). Glacier looks better etched. It is nice when it’s glossy, but the soft blue it becomes when etched is very hard to resist.
The beauty of CiM Glacier is in how well it mixes with Effetre pastels. When Glacier is superheated and swirled with Effetre Dark Ivory it still maintained it’s density and didn’t spread out as I expected a soft glass would. I had to really twist and twirl the two colours together to get some reaction. When superheating where Glacier and Ivory meet there is some frazzling, caramelising and mixing of the two colours. Although, if you do not superheat, you can keep a very sharp line between Glacier and any other opaque glass. I’ve personally fallen in love with the blend of Ivory, Glacier, Avocado and Copper Green.
When you pair Glacier with Effetre Violet Pastel a slight watercolour reaction occurs. Glacier will seep out over Violet Pastel in a way that looks remarkably like water paints. Moreover, Glacier in thin trails or stringer takes on a more lavender hue. It took me far too long to work this out, because I had pulled a bunch of Glacier stringer once and left them sitting in a jar with the purple stringers because I’d completely stopped paying attention that day. Much later I grabbed one of these “lavender” stringers and used them with Effetre Violet Pastel then when I was asked to repeat a bead, I couldn’t figure out what glass I’d used.
So, I went looking for a “lavender” glass that was giving me those lovely watercolour reactions and didn’t find one. If you look at the beads in the last photo, this is the reaction I’m talking about. A very thin layering of Glacier will look like pale lavender glass. Be mindful of this if you want blue trails or a slender tube bead to look more blue, you’re better off using a blue like CiM Zachary or CiM French Blue that doesn’t colour change when used in small quantities. Only recently did I put Glacier and Violet Pastel together again and there was the magic. I’ve gotten the same (but less intense) effect of layering Glacier stringer over other Effetre pastel purples and on CiM Gelly’s Sty as well. Etch the watercolour reaction sometime, it’s worth doing. Etching pulls out some striations.
However, CiM Cirrus and CiM Glacier do not play well together when Cirrus is used as a stringer design over Glacier, it will always devitrify. I haven’t noticed any other colours doing that over Glacier, it could be a quirk with Cirrus. It bears more investigation.
Glacier is a dependable blue that has a few little tricks waiting for you to discover. It fits so well with other soft muted colours and works equally well with fiery reds and yellows. It is a must have colour for your stash because it is so versatile.
