Northstar Berry Gumbolt is a fully opaque saturated dark blue. It is well suited for stringer application and blown work. It is not susceptible to reduction and is not flame sensitive. For best results, keep it in a neutral flame. It is a great backing color for such colors as Northstar Irrid and Northstar Turquesa, and goes well with Northstar Canary.
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.
