Question

write short note on glass production​

Answer 1

The history of glass-making dates back to at least 3600 years ago in Mesopotamia. However, some claim they may have been producing copies of glass objects from Egypt. Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt.The earliest known glass objects, of the mid second millennium BC, were beads, perhaps initially created as the accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreousmaterial made by a process similar to glazing. 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 India may have begun in 1730 BC. In ancient China, though, glass-making seems to have had a late start compared to ceramics and metal work. From across the former Roman Empirearchaeologists have recovered glass objects that were used in domestic, industrial and funerary contexts. Anglo-Saxon glass has been found across England during archaeological excavations of both settlement and cemetery sites. Glass in the Anglo-Saxon period was used in the manufacture of a range of objects including vessels, beads, windows and was even used in jewelry.

Answer 2

Answer:

for glass production , mixture of sand , soda , lime and small quantity of magnesium oxide is heated in furnace . sand i.e silicon dioxide melts at 1700 degree Celsius . so so as to melt the mixture at low temperature , pieces of discards glass are added to it . due to this , mixture molts at 85 degree Celsius

Glass production involves two main methods – the float glass process that produces sheet glass, and glassblowing that produces bottles and other containers. It has been done in a variety of ways during the history of glass.
