Egyptian Glass  Item 1873

Check Box for engraving


The Egyptians could work glass with great skill by the time of Pharaoh Akhenaten (1352-1336 BC).

But how did they make glass from raw material requiring temperatures of 2012 to 2102 degrees Fahrenheit?

In 1996, researchers at Sheffield University reconstructed Kiln 3 of the 3,300 year old Amarna archeological complex.

A mixture of Amarna desert sand, seaweed ash and cobalt were used in the experiment.

Although lime is necessary to make a stable glass, none was added in the experiment because Amarna sand contains natural lime

The experimental firing reached a maximum temperature of 2102F and spent several hours at 2012F.

It was expected that this firing would produce a well reacted frit, but it in fact produced an ingot of transparent blue glass, free of gas bubbles and unmelted quartz!
