NS-064 Lava is a bright intense opaque orange. It is very bright and well suited for stringer application and blown work. It is not terribly sensitive to flame chemistry but stay out of overly reducing flames. Lava however is heat sensitive so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the colour, but not necessary. Lava can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. A nice colour effect to try is a layer of NS-007 Ruby over NS-064 Lava.
