Yellow

Yellow 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, Yellow will yield a transparent golden yellow. If worked in a neutral to slightly reducing flame Yellow will start to darken and turn a semi opaque amber color. Because the strike can be easily controlled, Yellow can be used for sculpture, beads, and blown work without washing out or overpowering the work. Try layering Yellow over Ruby for a vibrant fuchsia color, and be sure to try it over Blue Exotic.

Available in Rod.
