Yellow
Northstar Yellow boro glass is an eye catching striking transparent yellow. It can be struck in a kiln or in the flame. This is another good forgiving striking color for those starting out. If it is worked in an oxidizing environment, NS-009 Yellow will yield a transparent golden yellow. If worked in a neutral to slightly reducing flame NS-009 Yellow will start to darken and turn a semi opaque amber color. Because the strike can be easily controlled, NS-009 Yellow can be used for sculpture, beads, and blown work without washing out or overpowering the work.
