Goldenrod is a bright, saturated intense opaque dark yellow. It is well suited for stringer application and thin blown work. It is not terribly sensitive to flame chemistry but stay out of overly reducing flames. Goldenrod however is heat sensitive so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the color, but not necessary. NS63 Canary can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. For a nice color effect layer NS13 Amber, Purple over Goldenrod.
