NS-063 Canary is a bright intense opaque lemon yellow. It is eye catching and is well suited for stringer application, and blown work. It is not terribly sensitive to flame chemistry but stay out of overly reducing flames. Canary 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. 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 NS-009 Yellow over NS-063 Canary. For additional information about the intense opaque colors refer to Northstar Newsletter 14.
