660516 Glass Alchemy Cobalt 6 Borosilicate Glass Rods.

Cobalt-6 was one of Glass Alchemy's early releases. The darkest of the Glass Alchemy cobalt colors we were faced with "how dark is too dark?" We had the millifiori maker and the stringer puller in mind when we developed this color. Now one of our most popular colors, it is used by many anytime they need a denser darker color. When drawn down to 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 color 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.   

Working Tip: Work in a neutral flame to avoid reduction. Also available as a frit. Size: Diameter 7mm, length 20". There is a 1/4 pound minimum per color. All Glass Alchemy rods are first quality.

ATTENTION: Due to the weight and length of the rods you may receive .30 pound vs .25 pound (as an example) when ordering. This will cause the cost to rise and the amount you expect to pay for your glass may change

If this is a problem, please let us know and we will “under weigh” your glass. This means instead of .25 pound you may receive .20 to .22 pound. Please be aware that it is almost impossible to pull exactly .25 pound. We will always try our best to get as close as possible to the weight that is ordered, but due to the factors stated, these weights may substantially increase the total cost of your order.
