The pink cups shown here are made from an erbium formulation that we recently melted at Firehouse Glass for the first half of Fritz Dreisbach's visit before the GAS conference. The opaline cups I plan to make more of and the swan stem goblets are tricky to make. There are so many parts to them and each is an opportunity to wreck the overall form. On the other hand, they are a terrific learning tool for a glass blower.
