Roman glass blowing techniques were adapted from conquered civizilations and were further developed and claimed as their own. With the invention of the blowing pipe technique, glass making was completely modernized and glass could be freely shaped by hand. Under the reign of the first Emperor Augustus (1st century BC) glass-making became an important industry in the Roman Empire. Glass bottles were popular and affordable, consequently used for oil, perfume, kohl and a whole range of other cosmetics, medicines and ointments. This beautiful glass was made by using sand, alkali, sodium carbonate, colouring agents (metals) and formed with burning seaweed and lime and was produced in a large range of colours, patterns and frequently complex techniques. It was an art, now lost, created by skilled craftsmen. It is believed, but not confirmed, that metals were used to affect the colour of the glass - copper to make turquoise to light blue, green, red or opaque red coloured glass. cobalt made the glass dark blue. Yellowish and purple glass was created by the use of manganese and antimony to make the glass opaque yellow or opaque white. Also iron was used to make a light blue, green, brown and black shades.
