Northstar Yellow tube is an eye catching striking transparent yellow. It can be struck in a kiln or in the flame. This is another good forgiving striking colour for those starting out. If it is worked in an oxidizing environment, Yellow will yield a transparent golden yellow. If worked in a neutral to slightly reducing flame it will start to darken and turn a semi opaque amber colour. Because the strike can be easily controlled, #NST09 Yellow can be used for sculpture, beads, and blown work without washing out or overpowering the work.
