Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
Producing the long neck of a bottle required more research. His first commercial bottle making machine was produced from 1904 to 1908. [56] Although the machine replaced glassblowers, it created more jobs because it increased demand for bottles. [57] The uniformity in bottle size led to new types of bottles: beer bottles, milk bottles, and baby ...
A water bottle is a container that is used to hold liquids, mainly water, for the purpose of transporting a drink while travelling or while otherwise away from a supply of potable water. Water bottles are usually made of plastic , glass , metal, or some combination of those substances.
This lowered the cost of bulbs by 90%, making them much more available for people. [3] He formed the Owens Bottle Machine Company in 1903. His machines could produce glass bottles at a rate of 240 per minute, and reduce labor costs by 80%. [4] Owens and Libbey entered into a partnership and the company was renamed the Owens Bottle Company in 1919.
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
The platinum-group metals [a] (PGMs) are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6). [1] The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum.
Stanley's new bottle was announced in The Berkshire Courier on July 8, 1915. Soon after, he established the Stanley Insulating Company in Great Barrington, Massachusetts, and began mass production of the bottle under the Ferrostat, and later Supervac, labels. He acquired financial backing for the company from his friend William H. Walker, who ...
Iron is the outlier at 1538 °C (2800 °F), [21] making it far more difficult to melt in antiquity. Cultures developed ironworking proficiency at different rates; however, evidence from the Near East suggests that smelting was possible but impractical circa 1500 BC, and relatively commonplace across most of Eurasia by 500 BC.
