Glass bottles and glass jars are found in many households worldwide. The first glass bottles were produced in Mesopotamia around 1500 B.C., and in the Roman Empire in around 1 AD. [ 1 ] America's glass bottle and glass jar industry was born in the early 1600s, when settlers in Jamestown built the first glass-melting furnace.

Laboratory glassware may be made from several types of glass, each with different capabilities and used for different purposes. Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion making it more resistant to thermal shock than most other glasses ...
Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.
