Roman glass was one of the most popular materials within the Roman Empire. The technique of glass-blowing revolutionised Roman glass technology from the 1st century AD. Glass items became so popular that other forms of Roman houseware became discontinued. Like in many cultures, coloured glass was used across the Roman Empire in jewellery and mosaics. Metal oxides were used to colour the naturally occurring aqua-hued glass. Amber tones were created with the addition of iron-sulfur, which was added to the silica and soda used to make Roman glass.
