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.
