Techniques developed during this period include 'slumping' viscous (but not fully molten) glass over a mould in order to form a dish and 'millefiori' (meaning 'thousand flowers') technique, where canes of multi-colored glass were sliced and the slices arranged together and fused in a mould to create a mosaic-like effect.It was also during this period that colorless or decolored glass began to be prized and methods for achieving this effect were investigated more fully.Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded.But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt.However, the first unmistakable evidence in large quantities, dating from the 3rd century BC, has been uncovered from the archaeological site in Takshashila, Pakistan, with bangles, beads, small vessels, and tiles discovered in quantity.However, the earliest archaeological evidence for glass manufacture in China comes from the late Zhou Dynasty (1046 BC to 221 BC).A growth of the use of glass products occurred throughout the Roman world. With the discovery of clear glass (through the introduction of manganese dioxide), by glass blowers in Alexandria circa 100 AD, the Romans began to use glass for architectural purposes.

The earliest vessels were 'core-formed', produced by winding a ductile rope of glass round a shaped core of sand and clay over a metal rod, then fusing it with repeated reheatings.Core-formed vessels and beads were still widely produced, but other techniques came to the fore with experimentation and technological advancements.During the Hellenistic period many new techniques of glass production were introduced and glass began to be used to make larger pieces, notably table wares.Glass products remained a luxury until the disasters that overtook the late Bronze Age civilizations seemingly brought glass-making to a halt.Development of glass technology in South Asia may have begun in 1730 BC.Over the next 1,000 years, glass making and working continued and spread through southern Europe and beyond.
