NS-72 Off-Color Glacier Blue

This is a off-batch of NS-072 Glacier Blue. This yield contains more cobalt, which in result, the glass is a more saturated blue & looks identical to NS-001 Cobalt. Although, this color contains copper, so make sure to work in an oxidizing flame to prevent red striking. When reduced, this color will yield some grey hazing as well as a red strike.
