A recent post about hand-mixed colours got me inspired to try a combination of CiM Cirrus and Eff Cobalt.
Of course - I chose Cobalt blue - a colour which simply will not reproduce on the screen. Sigh.
However, I was really pleased with the result. The Cirrus lightened up the cobalt enough that it really is a wonderful blue in real life - a real "Noxema jar" blue.
It is encouraging enough that I'm going to try more of it.
If you want to mix your own colours - you can mix just enough for a single bead by starting as if you are making a twisty - layering one colour on another - without having to be particularly neat about it. Use the second colour rod as a handle - and heat the mass of glass - just like a twisty - but not quite as hot and soupy. Hot enough to move the glass though. Then start twisting, but NOT pulling, just twist it in the flame. If it gets saggy and drippy - take it out of the flame, double it back onto itself, and keep twisting and folding it. If you blend this a lot, you get a very homogenous colour - if you don't blend as long, you get a more streaky colour. You can see from the bead above - this was very close to being completely blended. You can then pull it out into a fat stringer for later use, or, my preferred method, disconnect one rod, grab a mandrel and wind the mass of molten, variegated, glass onto the mandrel - and shape from there.
This is especially good for those uber-dark colours, Rubino Oro, Leaky Pen, Black Currant, that don't display well on their own.
