NS-063 Canary is a striking opaque lemon yellow. It is not very sensitive to flame chemistry, but it is still best to avoid over-reducing flames. Canary is heat-sensitive, however, so it must be handled carefully to avoid boiling, although it has less tendency to boil than Asian yellow, for example. Encasing with transparent is another method of masking the color, but not necessary.
