I use 70% strength Nitric. You will need low heat to get the reaction going. Brown fumes will appear. YOU MUST NOT BREATH THESE! Place the silver-containing object into the acid and wait until it dissolves. Let the acid cool down. Place a copper bar into the acid. Don't use wire or sheet as pieces will break off and fall to the bottom of the container. You will see a carpet of Silver forming on the copper bar. Give the bar a shake every now and then. It wll fall to the bottom. Leave it for 24 hours. The spongy carpet left at the bottom is your silver. Pour off the acid carefully and wash your silver thoroughly in distilled water. You will have 99% pure Silver. Melt and enjoy!
You get an alloy that makes no sense at all. Mercury, silver, tin and copper combine to produce dental amalgam, which is used in fillings. Tin and lead are used in solder (or at least used to be - thanks to the Reduction of Hazardous Substances, or ROHS, laws, solder is now lead-free) because the melt temperature is fairly low, but high enough that the thing you soldered together won't fall apart if it overheats. Throw a little copper and antimony in there and you get babbitt, which is a perfect metal for engine bearings. Brass is copper and zinc. Bronze is copper and tin. Iron is typically alloyed with carbon (this is steel). Then you can coat the steel with other metals. Coating with zinc is galvanizing, done to protect against rusting. Drawing steel into wire then coating it with copper gives the perfect radio-frequency cable - as strong as steel, as conductive as copper. And silver, copper and gold alloy together to produce karat gold. There are good reasons to alloy every metal on this list. But all in the same product? No. You'd have a very expensive, not very strong, potentially hazardous metal.
The major applications of copper are in electrical wires, roofing, industrial machinery, and plumbing. Many investors now look at copper as one of the better ways to play the global industrial cycle.
TASC typically calls the color copper as part of the Fall/Winter season color palette, usually around once a year. Copper is often favored for its warm and rich tones that complement the autumn and winter fashion trends.
Gold jewelry is typically made of a mixture called an alloy, which combines gold with other metals like silver, copper, nickel, or zinc. The purity of gold in jewelry is measured in karats, with 24k being pure gold and lower karat values indicating a lesser gold content mixed with other metals for strength and durability.
A metal is a shiny element that conducts electricity and heat.

what age group is most likely to fall age 60,65,70,80
There is one group that silicon and oxygen fall into. Silicate is the name of the group that both fall under.
No. Peace dollar are made of mostly silver so they shouldn't stick to a magnet. If yours does it's a fake. Someone tried to use cheap metals to make one and then sell it for a profit. Don't fall for this!

I have a art of chokin plate, and it from Japan and its was my great grandmothers plate from late 80's its gold, silver and copper; and its the fall wheel barrel with flowers. The only thing is I don't know what it is worth or who made it. Please help.

Fungi will fall under a group of organisms that are known as microbes. The other organisms in this group include archea, bacteria, protists and viruses.
