Amberina

Amberina is a type of two-toned glassware, which was originally made from 1883 to about 1900.

Amberina was patented by Joseph Locke of the New England Glass Company, and was produced extensively there.

The glass varies in colour from red to amber.

[2] Amberina is made of an amber glass containing some gold.

Its distinct colouring develops with applied reheating and cooling.
