611140 Northstar Ursa Borosilicate Glass Rods

Size: Diameter 5-7mm, length 20", weight per rod .07 lb. All Northstar rods are first quality.

Northstar says:  "Ursa is a response to our artists who have been asking for an opaque brown.  Due to environmental concerns, we have experimented with the alternatives to the industry standard cadmium based brown.  We have formulated NS-140 with a good working viscosity, as well as dense color saturation to help the artists explore this earth tone.  As with many opaque colors this glass can suffer from boiling issues if pushed too fast or hot"

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 “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.
