660515 Glass Alchemy Cobalt 5 Borosilicate Glass Rods.
One of Glass Alchemy's most popular colors, Cobalt-5 provides the artist with a highly saturated, easy to work blue. Be sure to use a neutral flame with this color as it can be susceptible to over reduction that will leave grey patches or streaks. Cobalt-5 is great for stringers and blown work that will leave you with a true deep cobalt. Sandwich between clear layers and blow out thin for a vibrant and beautiful cobalt blue transparent.
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.
