Northstar Bubblegum boro glass is a fully opaque flamingo pink. It is atmospherically stable so it can be worked in any flame without the color being affected. It is flame sensitive so heat it gently in a soft flame. Once it is heated Bubblegum will take a lot of heat without any boiling issues. Bubblegum is a great backing color and well suited for sculpture. Try it as a backing for NS-013 Amber/Purple, or NS-026 Double Amber/Purple.
