How insulated bottle is made - material, manufacture, …
The bottle-making process first became automated in 1865 with the introduction of a pressing and blowing machine. The first fully automatic machine for making various types of glass bottles and jars did not appear until 1903, however, when an employee of a Toledo, Ohio, lamp-chimney company named Michael J. Owens put the Owens Bottle Machine into commercial use.
Phase Diagram - Industrial Metallurgists
Iron-Carbon Phase Diagram An example of a commonly used phase diagram is the iron-carbon phase diagram, which is used to understand the phases present in steel. The amount of carbon present in an iron-carbon alloy, in weight percent, is plotted on the x-axis and temperature is plotted on the y-axis.
