Q:I have a copper canope above my fire but the copper has blue/green streaks. Standard brass/copper cleaner ( Brasso ) doesn't shift it. Any ideas ?: This won't be a neat fix but it will work. Get a can of Barkeeper's Friend. It's a powdered cleanser that is similar to scouring powder but not nearly as harsh and is wonderful on all metal! It's cheap and you can find it in a lot of grocery, hardware and discount stores. The cheapest place I've found it is WalMart. Dampen the canopy with a microfiber cloth and give it a good sprinkle. Take a sponge and work the product around an area evenly and walk away for about 10 minutes. Then come back and with the same damp sponge start polishing/scrubbing. Use a microfiber cloth to remove the dirty residue. Microfiber cloths wipe more thoroughly than anything else; otherwise you will be chasing smears for a week. I'd also suggest covering the stove with an old towel just to keep the mess from spreading. After you get the tarnish all off, take the wet microfiber cloth and really wipe the hood down and dry with a soft cloth to prevent spotting. If the copper is really tarnished, it's going to take a good deal of scrubbing but the Barkeeper's does work. I picked up a solid copper bowl at a sale and it was awful. Took several sessions with the cleanser to get it shiny but it looks wonderful now! Regular use will keep your canopy looking wonderful. I use the Barkeeper's on all my metals; stainless steel, copper, brass, silver and it works faster and more thoroughly than anything I've found. I also use it on my ceramic top range to clean those sneaky burned on spots. It's that gentle!

Q:We have pin holes forming in our copper pipes and we also have joints that are turning green. This is spring water and has been tested to be good, with ph in the 7.8-8.0 range. So my feeling is that it is so soft that it is acid. I need to know how to filter out the acid. Ionize or what do you recommend. jp: We have very soft, slightly alkaline water but we have had multiple pinhole leaks on the incoming cold water line. The pinhole leaks seem to get worse the closer the cold water pipe got to the water heater. When I changed out the water heater, I discovered that the plumber had used a cheap steel nipple on the cold water gate valve versus a brass nipple. Dissimilar metals (steel/copper) will generate a small voltage and cause electrolytic corrosion in the pipes. I also noted that the plumber must have been dunking the ends of the pipe in flux rather than applying the flux with a brush, the proper way to do it. The pipe joints were green and I found gobs of flux on the outside of the damaged pipe. When I looked inside the damaged pipe, I could see that the pinholes always occurred several inches downstream from a joint. It looked like there were remnants of flux on the inside of the damaged pipe. After I replaced the bad pipes and removed the steel nipple from the valve, we haven't had a pinhole leak for several years now.

Q:Why use copper tube for air conditioning refrigerant pipe?: Although the copper price is higher, but has the good thermal conductivity and the oxidation resistance, wantonly uses the copper tube generally.

Q:I am looking at getting one of these (I have risk factors for the hormonal Mirena IUD). Does anyone have any personal experience with the copper one? It seems like everyone I know has the Mirena instead.: I have the copper IUD and haven't had any problems with it. When I had it inserted it felt about the same as a pap smear. Had some mild cramping the rest of the day and the following day but Advil helped a lot. The copper IUD can cause you to have heavier periods and more cramping during your period, but since I have heavy periods to begin with I haven't really noticed any change. I also haven't had and more or less cramps than I used to, but everyone is different so everyone's body reacts differently. But I will say that, for me, it's been one of the best decisions I've made. Definitely worth talking to your doctor about.

Q:Refrigerator freezer room, the middle drawer, the back wall has 1cm copper tube naked leak, what's the matter? Why naked leak?: Bare for no reason, because the pipe from the back wall of the refrigerator, to connect to the top of each drawer evaporator coil, must be exposed, the low-end low-end refrigerator, there is no need for beautiful design occlusion or hidden.

Q:The materials one can use are a bunsen-burner, clay triangle, wooden splint/ triangle, crucible and cover.So by using only these materials how can one extract copper from copper carbonate?: Put the Copper carbonate in the crucible and heat it over the bunsen burner. The following reaction will happen: CuCO3 --heat-> CuO + CO2 you will see a change in color from blue/green to black. Now light your toothpick on fire and quickly put it in the crucible and put the cover on in such a way, that theres only a very little acces for air to enter he crucible. In that way you reduce the O2 in the crucible and when the wood burns it will form CO instead of CO2.....and it will burn at a slow rate. During the whole time you continue heating the crucible, and the following reaction will take place: CuO + CO ---> Cu + CO2 The copper is reduced to form its metallic form, and the carbon is oxidized from +2 in CO to +4 in CO2. Hope it helped!

Q:A copper wire at room temperature that is 1 mm thick and 30 cm long is connected to a 1 V battery. If all of the power goes into heating up the wire, find the temperature of the wire in 10s. (the density of copper is 8.9 g/cm3 and specific heat is 0.39 J/g·°C) I can't figure out this answer correctly. Thanks!!: ANZI said, ...T2=1925 'C Of course, if you try that experiment at home, the wire won't get anywhere near that hot. There are two reasons. One is the internal resistance of the battery. A real 1V battery would not be able to drive that many Amperes through the wire unless maybe it was around the size of an SUV. There would be less heat generated, and some of it would be generated within the battery itself. Reason number two is that the heat would not all build up in the wire. Much of it would be radiated away during the ten seconds that the current was applied.

Q:Can a Electrolysis be created by laying an insulated NM circuit wire on a Copper water pipe, in a residential home. I have some circuit wires in contact with the Copper water lines within the walls of my home. Just wondering if that could cause electrolysis, because the meaning of electrolysis states two uncommon metals coming in contact not an insulated wire in contact with copper water piping. And if there is another name for the type of electrolysis it causes that would be much appreciated, and where I can find the information. All of this because my electrician will not remove the wires from the copper tubing, and my plumber says it will cause electrolysis and ruin my anodeless rod inside the water heater, reducing the life of water heater.Well any information or websites that will help me prove the term electrolysis in reference to my situation will be much appreciated.: This Site Might Help You. RE: How is crude oil obtained? Please answer!!! Thank you! :)

Q:I know the price of copper has spiked. Has any mining operations resumed in the Keewanaw penisula due to this price rise?: with copper and other precious metals prices on the rise i expect to see many abandoned copper mines to be revived as long as prices stay where they are or higher. i believe the break even price of copper is 50 to 60 cents a pound.
