Northstar Turbo Cobalt is the most intense cobalt blue in the Northstar palette. It is great for stringer application and stretching out thin. If kept moderately thick, Turbo Cobalt is an excellent faux black. Because of it's intensity, Northstar Turbo Cobalt must be worked in a highly oxidizing flame to prevent graying. If however you are looking for a battleship grey, it can be achieved by working Turbo Cobalt in a heavily reducing flame. For a nice color combination, try layering Northstar Double Amber/Purple over Northstar Turbo Cobalt.
Size: Diameter 5-7mm, length 20", weight per rod .07 lb. All Northstar rods are first quality.
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 “underweigh” 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.
