it is a glass rod and it can be used for many many things
There is none. Glass is a mixture, not a pure substance and so does not have a chemical formula.
If the rod is made from pure iron it is not a mixture.
a glass rod is often used as a "Stir Stick" for mixing solutions or other materials as it is a tool that can be easily sterilized to prevent contamination in experiments. It also helpful when using acidic or basic chemicals which could potentially cause a reaction with standard metal stiring tools.

The Stirring rod is a long rod made of glass, but sometimes plastic, used to stir liquids. The rod is typically as thick as a pencil and between 6 and 12 inches long.

It's a short piece of cylindrical glass, usually about 12 cm long. It's used for stirring chemicals together. It's useful because glass is inert to most chemicals and won't contaminate anything.

Glass rods can be used to stir and displace liquids. Glass is often used because it does not react with many chemicals, especially acids.
A stirring rod is a glass rod, typically about 6 inches to 1 foot long and 1/8 to 1/4 inch in diameter that can be used to stir liquids in flasks or beakers.You can also use a stirring rod to help pour liquids without spilling. Because of surface tension, liquids tend to run down an object. So if you hold a glass rod vertically, with one end in the opening of the beaker or flask you are pouring into, and then hold the top end of the glass rod against the rim beaker you are pouring out of, the liquid will run down the rod and not spill. Be careful... it might take a little practice to get the proper technique!Sometimes, an attachment called a rubber policeman added to the end of the stirring rod. It is used to transfer residues of precipitates or solids from the inside or beakers, flasks or other glass surfaces. They are often made from rubber, but plastic ones can also be found.See the Web Links and Related Questions for more information and pictures.
