How can you make copper shavings?
Use a VERY coarse file, like a blacksmith file that you can get from a feed store.
What minerals are found in a nail file?
Emery is the mineral in a nail file
How do you make zinc acetate?
First find a source of zinc. If you live in the US, you can just file the copper layer off of a penny. Zinc can be ordered from United Nuclear. Then get some acetic acid, which is readily available as white vinegar. Place the zinc in the acetic acid and let it react. You can tell if it's reacting because it will produce hydrogen gas bubbles. If you're using a penny, don't worry about serious contamination, because copper reacts much more slowly than zinc. While it's reacting, you may see that a black layer is forming on top the zinc source. Just use sandpaper or a file to get it off, but it's not important. If you have zinc powder, you won't have to worry about this, because the reaction will happen much more quickly. Once it's done, let the solution evaporate, or boil it down for faster results. It will have a slight contamination of dark blue copper(II) acetate. It's not crucial to purify it, but it can be removed by placing more zinc into the solution. This will reduce copper(II) to copper metal, and oxidize zinc metal to zinc(II), forming more zinc acetate. It forms beautiful octahedral crystals. It burns teal in a flame, and can be used to color a fire. If you need extremely pure zinc acetate, you'd be better off buying it. But homemade zinc acetate is still cheap and useful.
Can a steel file scratch muscovite?
Yes it can.
What would reduce resistance in a copper wire?
Reduce the resistance:-- Use a shorter piece of wire.-- Use thicker wire.-- Cool the wire.Increase the resistance:-- Use a longer piece of wire.-- Use thinner wire.-- File a nick in the piece of wire you have.-- Stretch the wire.-- Heat the wire.

If you scratch a penny with an steel file, will the copper of the penny rub off on the file, or the steel (iron) of the file rub off on the penny?
The copper of the penny will rub off the file
What is the function of the file in the laboratory?
A triangular file is often used to stir chemicals, as well as to scratch glass tubing before breaking it.
What is the function of a triangular file in a laboratory?
Most commonly it's used to score small diameter glass tubing before breaking it so that it will break cleanly instead of shattering. Don't attempt to saw through the tubing with the file. If it won't break cleanly with a light score, you'll need to use a different technique such as scribing followed by thermal shock.

What is glass tubing and how it is used?
Glass tubing is exactly what it sounds like -- a tube made of glass. Glass tubing comes in all shapes in sizes, with tube diameters or just a millimeter or less up to very large tubes. It can be used for a number of things. I can be used to carry both liquid and gasses. With a triangular file, it is possible to break glass tubing into smaller pieces. Using a hot flame from a Bunsen burner, it is possible to bend glass tubing into other shapes.See the Web Links to the left for more information about how to use glass tubing.

What is harder a steel file can scratch a penknife blade or calcite scratches a copper coin?
the blade would be stronger because the copper would brake easier
What is the use of a triangular file?
The most common use of a triangular file in a chemistry laboratory is to score (scratch) and weaken small diameter glass tubing prior to breaking it. This makes the glass a) easier to break and b) more likely to break cleanly where the score is instead of randomly, leaving jagged edges. Pressure is applied on the OPPOSITE side of the score; remember to protect your hands with heavy gloves and/or a thick cloth.Large diameter tubing requires different methods; the "score and snap" technique tends not to work so well.

Can a rectangular file cut wood metal and plastic?
yes, it is possible although it seems like a bit of a stupid question to ask really as that is what a rectangular does, note the file is not for steel it can only be used on soft aluminum and soft metals such as copper. steel and iron would simply wear out the file and probably make sparks too.
