NS-52 Teal is an intense fully opaque bright seafoam green. It is great for stringer applications and thin blown work. With the recent reformulations the C.O.E. is far improved and is perfectly safe to use in encased work. Be sure to run a thorough annealing cycle when Teal is heavily encased. NS-52 Teal is not sensitive to atmosphere but it is recommended to work in a neutral flame. It has no heat issues and can be worked hot and long. Try encasing Teal with NS-48 Light Blue Amber/Purple for a nice effect.
