  information about glass and glass dropper bottles.
A little bit about glass.
The oldest records of glass are from 1700 BC in Mesopotamia, but Egyptian glassmakers began making pieces of jewelry as early as 3000 BC, as proven by the relics of a glass furnace dating back to about 1350 BC. The glass objects that have been found recently in Egypt and Mesopotamia share some similarities, but we don't know exactly when or where man began to make glass. Colored glass is made by adding minerals or salts. Below is a chart of common additives and the resulting color.
