The discovery of glass
Natural glass has existed since the beginnings of the solar system, formed from the melted
rocks as a result of high temperature such as volcanic eruptions, lightning strikes or the impact
of meteorites, and then coolded solidify rapidly. Stone age people is believed to have used
cutting tools made of obsidian and tektites.
According to the Roman naturalist Pliny (Gaius Plinius Secundus; AD 23-79), Phoenician
merchants transporting stone actually discovered glass (or rather became aware of its existence
accidentally) in the region of Syria around 1000 BC. Pliny tells how the merchants, after landing,
rested cooking pots on blocks of nitrate placed by their fire. With the intense heat of the fire, the
blocks eventually melted and mixed with the sand of the beach to form an opaque liquid.
Roman Glassmaking
Romans to be the leaders in glassmaking with the use of the blowpipe. It was thought to be most
likely created by a Phoenician artist around 50 A.D.; Roman glassmakers got their chance to master it.
The blowpipe allowed them to create new shapes and forms of glass. Finally, their works need not be
exclusively objects of luxury and their production costs were diminished. Then Roman people could
buy glass objects such as cups within affordable price. So the Glass is familiar to ordinary peoples
daily life.
Iridescence
The enamel-like shell covering the vessels is very brittle and susceptible to flaking.
The outer shell breaks away, it exposes the flimsier individual silica films beneath and disrupts their
integrity: the coatings become patchy and variable in thickness.
To the human eye, the patches scatter light in such a way as to produce a brilliant peacock feather
look that we call iridescence.
The environment in which the glass vessels are stored today must remain moist or else the layers
of silica gel will dry out and crumble. All the weathering layers are fragile and tend to break away
if the glass vessel is handled too often.
