Fenton, Amberina Glassware Replacements

Fenton Glass Amberina patterns glassware replacements from Robbins Nest.

Amberina glass was first developed by Joseph Locke at the New England Glass Company, in the USA, and patented by Locke in 1883. It is "heat sensitive" glass, which shades in colour from amber at the bottom to red at the top. This colour shading is due to the effects of reheating the top part of the glass before allowing it to cool. Amberina glass contains a precipitate of colloidal gold (as does gold ruby glass), which is heat sensitive and turns red at the right temperature.
If the effect is reversed and the bottom part of a vessel is reheated rather than the top, the result is called "reverse amberina"- which is red at the bottom and amber at the top.
After 1888 Amberina glass was made by the Libbey Glass Company. It is still popular today and is made by contemporary glass works such as Boyd in the USA.
