Artist Description by Mike Shelbo:
"A stiff, dense translucent cobalt blue, Cobalt-6 is so dense in colour saturation that it seems black.
When drawn down into extremely thin threads, it will still remain a deep cobalt blue transparent. Keep Cobalt-6 in the outer region of your flame length, in a mix of gas that will not reduce the colour if used without encasement. Grey streaks or patches could develop from too much propane in your torch flame, so using a neutral flame is best.
Cobalt-6 can be sandwiched between clear and blown out very thin while still having an intensely deep cobalt blue colour. Light transmitting through Cobalt-6 when colour layer is thin enough is very rich and pleasing" - Mike Shelbo
