Anotations

Scope note:

Refers to a type of glass that is blown from two colors combined in the molten state, creating streaks of various colors. It is often used to make windows, but may also be used to make vessels. It differs from "reamy glass" in that reamy glass generally contains white streaks and has the distinctive appearance of a colored liquid having been stirred into cream.
