Historical Context
Peacock Blue is a distinctive blue-green colour particularly associated with English glassmaking during the Napoleonic period.
During the late 18th century, British glassmakers relied heavily on cobalt imported from Saxony in Germany to produce the rich, deep blue glass commonly known as Bristol Blue.

However, the Napoleonic Wars (1803–1815), and particularly the Continental Blockade introduced in 1806, severely disrupted the supply of cobalt to Britain.
This shortage encouraged glassmakers to explore alternative colouring methods and is believed to have contributed to the increased use of lighter blue-green shades, including Peacock Blue, during the early 19th century.

These are rare glasses and wonderful examples from the period...the last example we had in this form and colour was in 2020.
