Gunpowder\nIt seems strange that the origins of one of the most important inventions in the history of mankind remains shrouded in mystery. A weak form of gunpowder was used by the Chinese early in the 11th Century. In Europe by the early 1300s, propellant charges for cannons were composed of charcoal, saltpeter, and sulphur, the ingredients for gunpowder. From this time on, there was a continuous development of more efficient firearms and more effective gunpowder. Powder mills were usually state-run enterprises in Europe because of the military uses of gunpowder. Despite the fact that gunpowder has generally been applied to destructive purposes, its commercial and industrial applications have been far-reaching. Its development permitted the more economic exploitation of natural resources (for example, in mining and tunneling), than would have otherwise been possible with the crude tools available before the l9th Century. Gunpowder and the technologies associated with it are neutral. When used by Neo-Tech thinkers to overcome the difficult conditions presented by nature, gunpowder's explosive qualities have been a boon to mankind. But when used to arm soldiers for conquering and subduing other men, it has served in the destructive ways of neocheaters and politicians.

This sounds too much like someone's homework!\n\nThe period is far to wide to narrow down any of the categories you want info in.  Perhaps you should actually look it up in some books - you know, actually do some research!

go to your blacksmiths ( i recommen WH Blacksmiths) don't forget to take about a ton of iron ore with you this can be found in Mordor or just that massive mountain by your house boy, after you have mined there and taken the ore in a wheelbarrow to the blacksmiths (or public forge) smelt the iron in the forge until it becomes soft and creamy, use a small tea spoon and if it melts in the ore then its ready. Pour the contents onto a bracket of somesort (please search on yahoo for the proper name) and pour cold water over the mould to cool the ore and create a chemical reaction. Get a big hammer and whack the sword and shield in to shape, hammer it in the morning and hammer in the evening just hammer all over the "stuff". Once you have zen. You can now sharpen the sword on a wheel and one of those foot pedals that make the wheel spin, lots of sparks will fly off, so wear protective goggles and ask an adult to help you. Tie a piece of string to the shield as a handle (at this point you will probably be on the school bus trying to get everything perfect and finished so this will save time). Sorry I cannot help you make a flail, try Walmart. Hope this helped , I made a shield and sword for my sons "Narnia" playset.

Cancer did not exist in the middle ages, because there were no vaccines.\nSo middle age technology is far better than today's 'technology', because it wasn't based on profit'\n\nYou might find much useful information by reading this interesting report.\n\nCancer\nhttp://dgwa1.fortunecity.com/body/cancer.html

Also check out the " Four Peaks Amethyst Mine", its in Arizona. It will give you additional information which you are seeking.

Gold in antiquity was relatively easy to obtain geologically; however, 75% of all gold ever produced has been extracted since 1910.[2] It has been estimated that all the gold in the world that has ever been refined would form a single cube 20 m (66 ft) a side.\n\nInterestingly, the World Book Encyclopedia we had when I was a kid, copyright about 1960, said 44 ft cube.

Read a book called Guns, Germs, and Steel or get it on video if you're lazy.  Basically the author of this book explains how geographic and climactic factors favored agriculture in Europe as their society evolved, this gave them a head start towards modern society.  Africa's climate continues to be less favorable for agriculture and industry.  And in many places their social structure remains focused on survival rather than "progress".  Thats not the whole story, but its a big piece of the puzzle.

They are also soft metals.  Easy to mine, easy to smelt.

During the 12th and 13th century in Europe there was a radical change in the rate of new inventions, innovations in the ways of managing traditional means of production, and economic growth. The period saw major technological advances, including the invention of cannons, spectacles and artesian wells; and the cross-cultural introduction of gunpowder, silk, compass and astrolabe from the east. There were also great improvements with ships and upon the clock. The latter advances made possible the dawn of the Age of Exploration.

It's not that they only occur in concentrations such as veins, but that they can only be mined when they happen to be concentrated.  Metallic elements can also be found widely distributed through the rocks of the earth.  However, elements like gold make up such a small part of the earth's composition that when they are not concentrated, you would need to process so much rock to get a tiny amount of the metal that the cost of mining and processing would exceed the value of the ore.  In that case, there's no reason to try to mine it, since miners are in business to make money.  For gold, the concentration needs to be a few ounces gold per ton of ore to be economical - that's still not much gold, but it's a lot more than is present on average.  For every metal, the break-even point is different.\n\nNow, about how they end up in veins.  The uncommon elements in the earth can only make their own minerals when they get concentrated.  In the bulk of the earth, these uncommon elements get taken up into common minerals by substituting a few of their atoms for a few atoms of the more \ncommon elements in that mineral's structure.  For example, rubidium or strontium may substitute for calcium in plagioclase feldspars and in calcite and uranium may substitute for zirconium in zircon.  Many economically valuable elements like gold and silver are examples of "incompatible" elements, that is, they do not easily fit into common types of minerals.  They go in because they have to, but they wait until the last possible opportunity and they also take the first possible opportunity to \nleave.  \n\nTo use gold as an example, a granite intrusion that is cooling a \ncrystallizing may contain a tiny amount of gold.  All through the cooling melt, elements are coming together to make crystals, but none of the gold is, yet.  As the amount of liquid decreases, the relative amount of the gold in it goes up, so this is the first step in concentration.  The final bits of the granite to crystallize will be enriched in gold.  When the granite is finally solid, but still hot, ground water and water that used to be dissolved in the magma  will be circulating through cracks in the granite.  When that hot water encounters minerals containing the gold, the \nincompatibility of the gold will lead those minerals to break down more easily than their neighbors and release the gold into solution.  As the water moves away from the granite, it is now carrying the gold, which is even more concentrated than it was before.  The water begins to cool off and as it does minerals begin to precipitate. Again, gold will remain in the solution as long as possible, so it is often one of the last things to crystallize.  By then, it may be concentrated enough that it will grow its own crystals of pure gold (small cubes, octahedrons, and wire-like shapes) rather than trying to fit into other crystal structures.  These minerals are left behind in the cracks that the water was moving through, forming veins.  It is those veins that the miners then follow as they mine their ore (rocks containing the concentrated gold, silver, or other metals).

ore is mined, then heated very hot. the rock and metals separate. the slag is filtered off the top.

The Romans were master machine builders.\n\n"They lifted heavy stones using cranes that were worked by windlasses or treadmills or the backs of men, they dredged harbors, emptied lakes, and drained swamps"\n\nI expect that they used more than one technique.  Dragging scooping sleds over the bottom when it was smooth, dragging nets when less smooth.   I imagine some sort of conveyor belt or waterwheel would have been used as well.

It's been around for along time:\n\nTin (anglo-Saxon, tin, Latin stannum) is one of the earliest metals known and was used as a component of bronze from antiquity. Because of its hardening effect on copper, tin was used in bronze implements as early as 3,500 BC. Tin mining is believed to have started in Cornwall and Devon ( esp Dartmoor) in Classical times, and a thriving tin trade developed with the civilizations of the Mediterranean. However the pure metal was not used until about 600 BC.
