The value that is returned from a call to a function is the value of that function call. For example, with that function we can set a variable to the value that is returned using the following code (which would set result to 5). var result = num(3,3); The difference between functions and other variables is that the function has to be run in order to determine its value.
Slag glass, also known as marble glass or malachite, is a type of opaque, streaked pressed glass.ne of the first glass foundries to produce slag glass (although it was not called that at the time) was the Gateshead, England, firm of Sowerby, which patented its recipe for purple malachite glass in 1878.
Granulated blast furnace slag is used as a mineral admixture for Portland cement concrete. Granulated blast furnace slag and vitrified pelletized blast furnace slag are also used in the manufacture of blended hydraulic cements.wo types of blast furnace slag such air-cooled slag and granulated slag are being generated from the steel plants. In most cases, this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately 2.90 with its bulk density varying in the range of 1200 1300 kg/m3.
