The earliest bottles or vessels were made by ancient man. Ingredients were melted to make glass and then clay forms were dipped into the molten liquid. When the glass cooled off, the clay was chipped out of the inside leaving just the hollow glass vessel. This glass was very thin as the fire was not as hot as modern day furnaces. The blowpipe was invented around 1 B.C. Now, molten glass could be gathered on the end of the blow pipe and blown into the other end to create a hollow vessel.
Once made, bottles may suffer from internal stresses as a result of unequal, or too rapid cooling. An annealing oven, or ‘lehr’ is used to cool glass containers slowly to prevent stress and make the bottle stronger. When a glass bottle filled with liquid is dropped or subjected to shock, the water hammer effect may cause hydrodynamic stress, breaking the bottle.
Modern bottles, when moulded, will be given marks on the heel (bottom) of the bottle. These marks serve a variety of purposes, such as identifying the machine used in the production of the bottle (for quality control purposes).
